Summary
The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n). Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd).

Summary
The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.

Summary
The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify. It is anticipated that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a certificate verification failure. The normal expected return value in this case would be 0. This issue also impacts the command line OpenSSL "ocsp" application. When verifying an ocsp response with the "-no_cert_checks" option the command line application will report that the verification is successful even though it has in fact failed. In this case the incorrect successful response will also be accompanied by error messages showing the failure and contradicting the apparently successful result. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).

"value": "The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify. It is anticipated that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a certificate verification failure. The normal expected return value in this case would be 0. This issue also impacts the command line OpenSSL \"ocsp\" application. When verifying an ocsp response with the \"-no_cert_checks\" option the command line application will report that the verification is successful even though it has in fact failed. In this case the incorrect successful response will also be accompanied by error messages showing the failure and contradicting the apparently successful result. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2)."

Summary
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.

Severity ?
EPSS score ?
Summary
In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780)

Summary
In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur.

Summary
In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure.

Summary
The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipient such that the modified data would still pass the MAC integrity check. Note that data sent from an OpenSSL 3.0 endpoint to a non-OpenSSL 3.0 endpoint will always be rejected by the recipient and the connection will fail at that point. Many application protocols require data to be sent from the client to the server first. Therefore, in such a case, only an OpenSSL 3.0 server would be impacted when talking to a non-OpenSSL 3.0 client. If both endpoints are OpenSSL 3.0 then the attacker could modify data being sent in both directions. In this case both clients and servers could be affected, regardless of the application protocol. Note that in the absence of an attacker this bug means that an OpenSSL 3.0 endpoint communicating with a non-OpenSSL 3.0 endpoint will fail to complete the handshake when using this ciphersuite. The confidentiality of data is not impacted by this issue, i.e. an attacker cannot decrypt data that has been encrypted using this ciphersuite - they can only modify it. In order for this attack to work both endpoints must legitimately negotiate the RC4-MD5 ciphersuite. This ciphersuite is not compiled by default in OpenSSL 3.0, and is not available within the default provider or the default ciphersuite list. This ciphersuite will never be used if TLSv1.3 has been negotiated. In order for an OpenSSL 3.0 endpoint to use this ciphersuite the following must have occurred: 1) OpenSSL must have been compiled with the (non-default) compile time option enable-weak-ssl-ciphers 2) OpenSSL must have had the legacy provider explicitly loaded (either through application code or via configuration) 3) The ciphersuite must have been explicitly added to the ciphersuite list 4) The libssl security level must have been set to 0 (default is 1) 5) A version of SSL/TLS below TLSv1.3 must have been negotiated 6) Both endpoints must negotiate the RC4-MD5 ciphersuite in preference to any others that both endpoints have in common Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).

Summary
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

Summary
scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows."

Summary
In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption.

Summary
The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. This function is used when decoding certificates or keys. If a long lived process periodically decodes certificates or keys its memory usage will expand without bounds and the process might be terminated by the operating system causing a denial of service. Also traversing the empty hash table entries will take increasingly more time. Typically such long lived processes might be TLS clients or TLS servers configured to accept client certificate authentication. The function was added in the OpenSSL 3.0 version thus older releases are not affected by the issue. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).

Summary
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free.

Vulnerability from fkie_nvd
Published
2019-12-23 19:15
Modified
2024-11-21 04:44
Severity ?
Summary
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.

An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed.

Summary
scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows."

Vulnerability from fkie_nvd

Severity ?
Summary
The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify. It is anticipated that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a certificate verification failure. The normal expected return value in this case would be 0. This issue also impacts the command line OpenSSL "ocsp" application. When verifying an ocsp response with the "-no_cert_checks" option the command line application will report that the verification is successful even though it has in fact failed. In this case the incorrect successful response will also be accompanied by error messages showing the failure and contradicting the apparently successful result. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).

Summary
In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption.

Summary
The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. This function is used when decoding certificates or keys. If a long lived process periodically decodes certificates or keys its memory usage will expand without bounds and the process might be terminated by the operating system causing a denial of service. Also traversing the empty hash table entries will take increasingly more time. Typically such long lived processes might be TLS clients or TLS servers configured to accept client certificate authentication. The function was added in the OpenSSL 3.0 version thus older releases are not affected by the issue. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).

"value": "The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. This function is used when decoding certificates or keys. If a long lived process periodically decodes certificates or keys its memory usage will expand without bounds and the process might be terminated by the operating system causing a denial of service. Also traversing the empty hash table entries will take increasingly more time. Typically such long lived processes might be TLS clients or TLS servers configured to accept client certificate authentication. The function was added in the OpenSSL 3.0 version thus older releases are not affected by the issue. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2)."

Summary
In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780)

Vulnerability from fkie_nvd
Published

Modified
2024-11-21 04:32
Severity ?
Summary
The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.

Summary
In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure.

Vulnerability from fkie_nvd

Severity ?
Summary
The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipient such that the modified data would still pass the MAC integrity check. Note that data sent from an OpenSSL 3.0 endpoint to a non-OpenSSL 3.0 endpoint will always be rejected by the recipient and the connection will fail at that point. Many application protocols require data to be sent from the client to the server first. Therefore, in such a case, only an OpenSSL 3.0 server would be impacted when talking to a non-OpenSSL 3.0 client. If both endpoints are OpenSSL 3.0 then the attacker could modify data being sent in both directions. In this case both clients and servers could be affected, regardless of the application protocol. Note that in the absence of an attacker this bug means that an OpenSSL 3.0 endpoint communicating with a non-OpenSSL 3.0 endpoint will fail to complete the handshake when using this ciphersuite. The confidentiality of data is not impacted by this issue, i.e. an attacker cannot decrypt data that has been encrypted using this ciphersuite - they can only modify it. In order for this attack to work both endpoints must legitimately negotiate the RC4-MD5 ciphersuite. This ciphersuite is not compiled by default in OpenSSL 3.0, and is not available within the default provider or the default ciphersuite list. This ciphersuite will never be used if TLSv1.3 has been negotiated. In order for an OpenSSL 3.0 endpoint to use this ciphersuite the following must have occurred: 1) OpenSSL must have been compiled with the (non-default) compile time option enable-weak-ssl-ciphers 2) OpenSSL must have had the legacy provider explicitly loaded (either through application code or via configuration) 3) The ciphersuite must have been explicitly added to the ciphersuite list 4) The libssl security level must have been set to 0 (default is 1) 5) A version of SSL/TLS below TLSv1.3 must have been negotiated 6) Both endpoints must negotiate the RC4-MD5 ciphersuite in preference to any others that both endpoints have in common Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).

Therefore, in such a case, only an OpenSSL 3.0 server would be impacted when talking to a non-OpenSSL 3.0 client. If both endpoints are OpenSSL 3.0 then the attacker could modify data being sent in both directions. In this case both clients and servers could be affected, regardless of the application protocol. Note that in the absence of an attacker this bug means that an OpenSSL 3.0 endpoint communicating with a non-OpenSSL 3.0 endpoint will fail to complete the handshake when using this ciphersuite. The confidentiality of data is not impacted by this issue, i.e. an attacker cannot decrypt data that has been encrypted using this ciphersuite - they can only modify it. In order for this attack to work both endpoints must legitimately negotiate the RC4-MD5 ciphersuite. This ciphersuite is not compiled by default in OpenSSL 3.0, and is not available within the default provider or the default ciphersuite list. This ciphersuite will never be used if TLSv1.3 has been negotiated. In order for an OpenSSL 3.0 endpoint to use this ciphersuite the following must have occurred: 1) OpenSSL must have been compiled with the (non-default) compile time option enable-weak-ssl-ciphers 2) OpenSSL must have had the legacy provider explicitly loaded (either through application code or via configuration) 3) The ciphersuite must have been explicitly added to the ciphersuite list 4) The libssl security level must have been set to 0 (default is 1) 5) A version of SSL/TLS below TLSv1.3 must have been negotiated 6) Both endpoints must negotiate the RC4-MD5 ciphersuite in preference to any others that both endpoints have in common Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2)."

"value": "La implementaci\u00f3n de OpenSSL versi\u00f3n 3.0 del cifrado RC4-MD5 usa incorrectamente los datos AAD como clave MAC. Esto hace que la clave MAC sea trivialmente predecible. Un atacante podr\u00eda aprovechar este problema llevando a cabo un ataque de intermediario para modificar los datos que son enviados desde un endpoint a un destinatario de OpenSSL versi\u00f3n 3.0 de forma que los datos modificados sigan pasando la comprobaci\u00f3n de integridad MAC. Tenga en cuenta que los datos enviados desde un endpoint OpenSSL versi\u00f3n 3.0 a un endpoint no OpenSSL versi\u00f3n 3.0 siempre ser\u00e1n rechazados por el destinatario y la conexi\u00f3n fallar\u00e1 en ese punto. Muchos protocolos de aplicaci\u00f3n requieren que los datos sean enviados primero desde el cliente al servidor. Por lo tanto, en tal caso, s\u00f3lo un servidor OpenSSL versi\u00f3n 3.0 estar\u00eda afectado cuando hablara con un cliente no OpenSSL versi\u00f3n 3.0. Si ambos endpoints son OpenSSL versi\u00f3n 3.0, el atacante podr\u00eda modificar los datos que son enviados en ambas direcciones. En este caso, tanto los clientes como los servidores podr\u00edan verse afectados, independientemente del protocolo de aplicaci\u00f3n. Tenga en cuenta que, en ausencia de un atacante, este fallo significa que un endpoint de OpenSSL 3.0 que sea comunicado con un endpoint que no sea de OpenSSL 3.0 no podr\u00e1 completar el apret\u00f3n de manos cuando sea usado este cifrado. La confidencialidad de los datos no est\u00e1 afectada por este problema, es decir, un atacante no puede descifrar los datos que han sido encriptados usando este cifrado, s\u00f3lo puede modificarlos. Para que este ataque funcione, ambos endpoints deben negociar leg\u00edtimamente el cifrado RC4-MD5. Este ciphersuite no est\u00e1 compilado por defecto en OpenSSL versi\u00f3n 3.0, y no est\u00e1 disponible en el proveedor por defecto o en la lista de ciphersuite por defecto. Esta ciphersuite nunca ser\u00e1 usado si ha sido negociado TLSv1.3. Para que un endpoint de OpenSSL versi\u00f3n 3.0 use esta ciphersuite debe haber ocurrido lo siguiente 1) OpenSSL debe haber sido compilado con la opci\u00f3n de tiempo de compilaci\u00f3n (no predeterminada) enable-weak-ssl-ciphers 2) OpenSSL debe tener el proveedor heredado cargado expl\u00edcitamente (ya sea a trav\u00e9s del c\u00f3digo de la aplicaci\u00f3n o por medio de la configuraci\u00f3n) 3) La ciphersuite debe haber sido a\u00f1adida expl\u00edcitamente a la lista de ciphersuite 4) El nivel de seguridad de libssl debe haber sido establecido en 0 (el valor predeterminado es 1) 5) Una versi\u00f3n de SSL/TLS inferior a TLSv1. 3 debe haber sido negociada 6) Ambos endpoints deben negociar el ciphersuite RC4-MD5 con preferencia a cualquier otro que ambos endpoints tengan en com\u00fan Corregido en OpenSSL versi\u00f3n 3.0.3 (Afectado 3.0.0,3.0.1,3.0.2)"

Severity ?
Summary
The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n). Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd).

- ========================================================================= Ubuntu Security Notice USN-5130-1 November 09, 2021
linux vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 ESM
Summary:
Several security issues were fixed in the Linux kernel. (CVE-2020-29660)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 ESM: linux-image-3.13.0-188-generic 3.13.0-188.239 linux-image-3.13.0-188-lowlatency 3.13.0-188.239 linux-image-generic 3.13.0.188.197 linux-image-lowlatency 3.13.0.188.197 linux-image-server 3.13.0.188.197 linux-image-virtual 3.13.0.188.197
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
CVE-2020-27815
A flaw was reported in the JFS filesystem code allowing a local
attacker with the ability to set extended attributes to cause a
denial of service.
CVE-2020-27825
Adam 'pi3' Zabrocki reported a use-after-free flaw in the ftrace
ring buffer resizing logic due to a race condition, which could
result in denial of service or information leak.
CVE-2020-27830
Shisong Qin reported a NULL pointer dereference flaw in the Speakup
screen reader core driver.
CVE-2020-28374
David Disseldorp discovered that the LIO SCSI target implementation
performed insufficient checking in certain XCOPY requests. An
attacker with access to a LUN and knowledge of Unit Serial Number
assignments can take advantage of this flaw to read and write to any
LIO backstore, regardless of the SCSI transport settings.
CVE-2020-29568 (XSA-349)
Michael Kurth and Pawel Wieczorkiewicz reported that frontends can
trigger OOM in backends by updating a watched path.
CVE-2020-29569 (XSA-350)
Olivier Benjamin and Pawel Wieczorkiewicz reported a use-after-free
flaw which can be triggered by a block frontend in Linux blkback. A
misbehaving guest can trigger a dom0 crash by continuously
connecting / disconnecting a block frontend. A local attacker can take advantage of
this flaw for memory corruption or privilege escalation.
CVE-2020-36158
A buffer overflow flaw was discovered in the mwifiex WiFi driver
which could result in denial of service or the execution of
arbitrary code via a long SSID value.
CVE-2021-3347
It was discovered that PI futexes have a kernel stack use-after-free
during fault handling. An unprivileged user could use this flaw to
crash the kernel (resulting in denial of service) or for privilege
escalation.
CVE-2021-20177
A flaw was discovered in the Linux implementation of string matching
within a packet. A privileged user (with root or CAP_NET_ADMIN) can
take advantage of this flaw to cause a kernel panic when inserting
iptables rules.
For the stable distribution (buster), these problems have been fixed in version 4.19.171-2.
We recommend that you upgrade your linux packages.

An\n attacker with access to a LUN and knowledge of Unit Serial Number\n assignments can take advantage of this flaw to read and write to any\n LIO backstore, regardless of the SCSI transport settings. \n\nCVE-2020-29568 (XSA-349)\n\n Michael Kurth and Pawel Wieczorkiewicz reported that frontends can\n trigger OOM in backends by updating a watched path. \n\nCVE-2020-29569 (XSA-350)\n\n Olivier Benjamin and Pawel Wieczorkiewicz reported a use-after-free\n flaw which can be triggered by a block frontend in Linux blkback. A\n misbehaving guest can trigger a dom0 crash by continuously\n connecting / disconnecting a block frontend. A local attacker can take advantage of\n this flaw for memory corruption or privilege escalation. \n\nCVE-2020-36158\n\n A buffer overflow flaw was discovered in the mwifiex WiFi driver\n which could result in denial of service or the execution of\n arbitrary code via a long SSID value. \n\nCVE-2021-3347\n\n It was discovered that PI futexes have a kernel stack use-after-free\n during fault handling. An unprivileged user could use this flaw to\n crash the kernel (resulting in denial of service) or for privilege\n escalation. \n\nCVE-2021-20177\n\n A flaw was discovered in the Linux implementation of string matching\n within a packet. A privileged user (with root or CAP_NET_ADMIN) can\n take advantage of this flaw to cause a kernel panic when inserting\n iptables rules. \n\nFor the stable distribution (buster), these problems have been fixed in\nversion 4.19.171-2. \n\nWe recommend that you upgrade your linux packages. \n\nFor the detailed security status of linux please refer to its security\ntracker page at:\nhttps://security-tracker.debian.org/tracker/linux\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nj3wO/r/1gut/bK/OJnjmOB9J5OXP+cHxYtrhPqXFy2Hzkgj1CRU=\n=u23W\n-----END PGP SIGNATURE-----\n",

- ========================================================================== Ubuntu Security Notice USN-4752-1 February 25, 2021
linux-oem-5.6 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-oem-5.6: Linux kernel for OEM systems
Details:
Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered that legacy pairing and secure-connections pairing authentication in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. A physically proximate attacker could use this to impersonate a previously paired Bluetooth device. (CVE-2020-10135)
Jay Shin discovered that the ext4 file system implementation in the Linux kernel did not properly handle directory access with broken indexing, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-14314)
It was discovered that the block layer implementation in the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-15436)
It was discovered that the serial port driver in the Linux kernel did not properly initialize a pointer in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2020-15437)
Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-24490)
It was discovered that the NFS client implementation in the Linux kernel did not properly perform bounds checking before copying security labels in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)
It was discovered that the Rados block device (rbd) driver in the Linux kernel did not properly perform privilege checks for access to rbd devices in some situations. A local attacker could use this to map or unmap rbd block devices. (CVE-2020-25284)
It was discovered that the block layer subsystem in the Linux kernel did not properly handle zero-length requests. A local attacker could use this to cause a denial of service. (CVE-2020-25641)
It was discovered that the HDLC PPP implementation in the Linux kernel did not properly validate input in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25643)
Kiyin (尹亮) discovered that the perf subsystem in the Linux kernel did not properly deallocate memory in some situations. A privileged attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2020-25704)
It was discovered that the KVM hypervisor in the Linux kernel did not properly handle interrupts in certain situations. A local attacker in a guest VM could possibly use this to cause a denial of service (host system crash). (CVE-2020-27152)
It was discovered that the jfs file system implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to possibly cause a denial of service (system crash). (CVE-2020-27815)
It was discovered that an information leak existed in the syscall implementation in the Linux kernel on 32 bit systems. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2020-28588)
It was discovered that the framebuffer implementation in the Linux kernel did not properly perform range checks in certain situations. A local attacker could use this to expose sensitive information (kernel memory). A local attacker could use this to gain unintended write access to read-only memory pages. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-29369)
Jann Horn discovered that the romfs file system in the Linux kernel did not properly validate file system meta-data, leading to an out-of-bounds read. An attacker could use this to construct a malicious romfs image that, when mounted, exposed sensitive information (kernel memory). (CVE-2020-29371)
Jann Horn discovered that the tty subsystem of the Linux kernel did not use consistent locking in some situations, leading to a read-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2020-29660)
Jann Horn discovered a race condition in the tty subsystem of the Linux kernel in the locking for the TIOCSPGRP ioctl(), leading to a use-after- free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-35508)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: linux-image-5.6.0-1048-oem 5.6.0-1048.52 linux-image-oem-20.04 5.6.0.1048.44
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

A\nphysically proximate attacker could use this to impersonate a previously\npaired Bluetooth device. (CVE-2020-10135)\n\nJay Shin discovered that the ext4 file system implementation in the Linux\nkernel did not properly handle directory access with broken indexing,\nleading to an out-of-bounds read vulnerability. A local attacker could use\nthis to cause a denial of service (system crash). (CVE-2020-14314)\n\nIt was discovered that the block layer implementation in the Linux kernel\ndid not properly perform reference counting in some situations, leading to\na use-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash). (CVE-2020-15436)\n\nIt was discovered that the serial port driver in the Linux kernel did not\nproperly initialize a pointer in some situations. A local attacker could\npossibly use this to cause a denial of service (system crash). \n(CVE-2020-15437)\n\nAndy Nguyen discovered that the Bluetooth HCI event packet parser in the\nLinux kernel did not properly handle event advertisements of certain sizes,\nleading to a heap-based buffer overflow. A physically proximate remote\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2020-24490)\n\nIt was discovered that the NFS client implementation in the Linux kernel\ndid not properly perform bounds checking before copying security labels in\nsome situations. A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. (CVE-2020-25212)\n\nIt was discovered that the Rados block device (rbd) driver in the Linux\nkernel did not properly perform privilege checks for access to rbd devices\nin some situations. A local attacker could use this to map or unmap rbd\nblock devices. (CVE-2020-25284)\n\nIt was discovered that the block layer subsystem in the Linux kernel did\nnot properly handle zero-length requests. A local attacker could use this\nto cause a denial of service. (CVE-2020-25641)\n\nIt was discovered that the HDLC PPP implementation in the Linux kernel did\nnot properly validate input in some situations. A local attacker could use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2020-25643)\n\nKiyin (\u5c39\u4eae) discovered that the perf subsystem in the Linux kernel did\nnot properly deallocate memory in some situations. A privileged attacker\ncould use this to cause a denial of service (kernel memory exhaustion). \n(CVE-2020-25704)\n\nIt was discovered that the KVM hypervisor in the Linux kernel did not\nproperly handle interrupts in certain situations. A local attacker in a\nguest VM could possibly use this to cause a denial of service (host system\ncrash). (CVE-2020-27152)\n\nIt was discovered that the jfs file system implementation in the Linux\nkernel contained an out-of-bounds read vulnerability. A local attacker\ncould use this to possibly cause a denial of service (system crash). \n(CVE-2020-27815)\n\nIt was discovered that an information leak existed in the syscall\nimplementation in the Linux kernel on 32 bit systems. A local attacker\ncould use this to expose sensitive information (kernel memory). \n(CVE-2020-28588)\n\nIt was discovered that the framebuffer implementation in the Linux kernel\ndid not properly perform range checks in certain situations. A local\nattacker could use this to expose sensitive information (kernel memory). A local attacker could use\nthis to gain unintended write access to read-only memory pages. A local attacker could use this to cause a\ndenial of service (system crash) or possibly expose sensitive information. \n(CVE-2020-29369)\n\nJann Horn discovered that the romfs file system in the Linux kernel did not\nproperly validate file system meta-data, leading to an out-of-bounds read. \nAn attacker could use this to construct a malicious romfs image that, when\nmounted, exposed sensitive information (kernel memory). (CVE-2020-29371)\n\nJann Horn discovered that the tty subsystem of the Linux kernel did not use\nconsistent locking in some situations, leading to a read-after-free\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly expose sensitive information (kernel memory). \n(CVE-2020-29660)\n\nJann Horn discovered a race condition in the tty subsystem of the Linux\nkernel in the locking for the TIOCSPGRP ioctl(), leading to a use-after-\nfree vulnerability. A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. \n(CVE-2020-35508)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 20.04 LTS:\n linux-image-5.6.0-1048-oem 5.6.0-1048.52\n linux-image-oem-20.04 5.6.0.1048.44\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. \n\nReferences:\n https://usn.ubuntu.com/4752-1\n CVE-2020-10135, CVE-2020-14314, CVE-2020-15436, CVE-2020-15437,\n CVE-2020-24490, CVE-2020-25212, CVE-2020-25284, CVE-2020-25641,\n CVE-2020-25643, CVE-2020-25704, CVE-2020-27152, CVE-2020-27815,\n CVE-2020-28588, CVE-2020-28915, CVE-2020-29368, CVE-2020-29369,\n CVE-2020-29371, CVE-2020-29660, CVE-2020-29661, CVE-2020-35508\n\nPackage Information:\n https://launchpad.net/ubuntu/+source/linux-oem-5.6/5.6.0-1048.52\n",

Matt Delco discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform bounds checking when handling coalesced MMIO write operations. A local attacker with write access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-14821)
Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel did not properly validate device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15117)
Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel improperly performed recursion while handling device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15118)
It was discovered that the Technisat DVB-S/S2 USB device driver in the Linux kernel contained a buffer overread. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-15505)
Brad Spengler discovered that a Spectre mitigation was improperly implemented in the ptrace susbsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information. (CVE-2019-15902)
It was discovered that the SMB networking file system implementation in the Linux kernel contained a buffer overread. An attacker could use this to expose sensitive information (kernel memory). (CVE-2019-15918)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 ESM: linux-image-4.15.0-1061-azure 4.15.0-1061.66~14.04.1 linux-image-azure 4.15.0.1061.47
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

"data": "There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Linux Kernel Contains a classic buffer overflow vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. =========================================================================\nUbuntu Security Notice USN-4162-2\nOctober 23, 2019\n\nlinux-azure vulnerabilities\n=========================================================================\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 14.04 ESM\n\nSummary:\n\nSeveral security issues were fixed in the Linux kernel. This update provides the corresponding updates for the Linux\nkernel for Microsoft Azure Cloud systems for Ubuntu 14.04 ESM. \n\nIt was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not\ndid not handle detach operations correctly, leading to a use-after-free\nvulnerability. (CVE-2019-14814,\nCVE-2019-14815, CVE-2019-14816)\n\nMatt Delco discovered that the KVM hypervisor implementation in the Linux\nkernel did not properly perform bounds checking when handling coalesced\nMMIO write operations. A local attacker with write access to /dev/kvm could\nuse this to cause a denial of service (system crash). (CVE-2019-14821)\n\nHui Peng and Mathias Payer discovered that the USB audio driver for the\nLinux kernel did not properly validate device meta data. A physically\nproximate attacker could use this to cause a denial of service (system\ncrash). (CVE-2019-15117)\n\nHui Peng and Mathias Payer discovered that the USB audio driver for the\nLinux kernel improperly performed recursion while handling device meta\ndata. A physically proximate attacker could use this to cause a denial of\nservice (system crash). (CVE-2019-15118)\n\nIt was discovered that the Technisat DVB-S/S2 USB device driver in the\nLinux kernel contained a buffer overread. A physically proximate attacker\ncould use this to cause a denial of service (system crash) or possibly\nexpose sensitive information. (CVE-2019-15505)\n\nBrad Spengler discovered that a Spectre mitigation was improperly\nimplemented in the ptrace susbsystem of the Linux kernel. A local attacker\ncould possibly use this to expose sensitive information. (CVE-2019-15902)\n\nIt was discovered that the SMB networking file system implementation in the\nLinux kernel contained a buffer overread. An attacker could use this to\nexpose sensitive information (kernel memory). (CVE-2019-15918)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 14.04 ESM:\n linux-image-4.15.0-1061-azure 4.15.0-1061.66~14.04.1\n linux-image-azure 4.15.0.1061.47\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA256\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: kernel security and bug fix update\nAdvisory ID: RHSA-2020:0374-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://access.redhat.com/errata/RHSA-2020:0374\nIssue date: 2020-02-04\nCVE Names: CVE-2019-14816 CVE-2019-14895 CVE-2019-14898 \n CVE-2019-14901 CVE-2019-17133 \n=====================================================================\n\n1.

Summary:
Several security issues were fixed in the kernel.
Software Description: - linux: Linux kernel
Details:
It was discovered that a race condition existed in the GFS2 file system in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2016-10905)
It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. (CVE-2018-20856)
It was discovered that the USB gadget Midi driver in the Linux kernel contained a double-free vulnerability when handling certain error conditions. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-20961)
It was discovered that the XFS file system in the Linux kernel did not properly handle mount failures in some situations. (CVE-2018-20976)
It was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not did not handle detach operations correctly, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-21008)
It was discovered that the Intel Wi-Fi device driver in the Linux kernel did not properly validate certain Tunneled Direct Link Setup (TDLS). A physically proximate attacker could use this to cause a denial of service (Wi-Fi disconnect). (CVE-2019-0136)
It was discovered that the Linux kernel on ARM processors allowed a tracing process to modify a syscall after a seccomp decision had been made on that syscall. A local attacker could possibly use this to bypass seccomp restrictions. (CVE-2019-2054)
It was discovered that an integer overflow existed in the Binder implementation of the Linux kernel, leading to a buffer overflow. A local attacker could use this to escalate privileges. (CVE-2019-2181)
It was discovered that the Marvell Wireless LAN device driver in the Linux kernel did not properly validate the BSS descriptor. (CVE-2019-10126)
It was discovered that the Bluetooth UART implementation in the Linux kernel did not properly check for missing tty operations. A local attacker could use this to cause a denial of service. (CVE-2019-10207)
Jonathan Looney discovered that an integer overflow existed in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service (system crash). (CVE-2019-11477)
Jonathan Looney discovered that the TCP retransmission queue implementation in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service. (CVE-2019-11478)
It was discovered that the ext4 file system implementation in the Linux kernel did not properly zero out memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-11833)
It was discovered that the PowerPC dlpar implementation in the Linux kernel did not properly check for allocation errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-12614)
It was discovered that the floppy driver in the Linux kernel did not properly validate meta data, leading to a buffer overread. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14283)
It was discovered that the floppy driver in the Linux kernel did not properly validate ioctl() calls, leading to a division-by-zero. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-14284)
Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. (CVE-2019-14814)
Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. (CVE-2019-14815)
Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. (CVE-2019-14816)
Matt Delco discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform bounds checking when handling coalesced MMIO write operations. A local attacker with write access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-14821)
Peter Pi discovered a buffer overflow in the virtio network backend (vhost_net) implementation in the Linux kernel. (CVE-2019-14835)

Installation instructions: +------------------------+
Upgrade the packages as root:
upgradepkg kernel-*.txz
If you are using an initrd, you'll need to rebuild it.
For a 32-bit SMP machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2):
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.199-smp | bash
For a 64-bit machine, or a 32-bit uniprocessor machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2):
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.199 | bash
Please note that "uniprocessor" has to do with the kernel you are running, not with the CPU. Most systems should run the SMP kernel (if they can) regardless of the number of cores the CPU has. If you aren't sure which kernel you are running, run "uname -a". If you see SMP there, you are running the SMP kernel and should use the 4.4.199-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 4.4.199 as the version.
If you are using lilo or elilo to boot the machine, you'll need to ensure that the machine is properly prepared before rebooting.
If using LILO: By default, lilo.conf contains an image= line that references a symlink that always points to the correct kernel. No editing should be required unless your machine uses a custom lilo.conf. If that is the case, be sure that the image= line references the correct kernel file. Either way, you'll need to run "lilo" as root to reinstall the boot loader.
If using elilo: Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish to use, and then run eliloconfig to update the EFI System Partition.

Please do not reply to this email address. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 19.04 for Ubuntu 18.04 LTS. Please note that the RDS protocol is blacklisted in Ubuntu by default. (CVE-2019-2181)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS: linux-image-5.0.0-1021-gcp 5.0.0-1021.21~18.04.1 linux-image-5.0.0-1023-azure 5.0.0-1023.24~18.04.1 linux-image-5.0.0-1023-gke 5.0.0-1023.23~18.04.2 linux-image-5.0.0-32-generic 5.0.0-32.34~18.04.2 linux-image-5.0.0-32-generic-lpae 5.0.0-32.34~18.04.2 linux-image-5.0.0-32-lowlatency 5.0.0-32.34~18.04.2 linux-image-azure 5.0.0.1023.33 linux-image-gcp 5.0.0.1021.26 linux-image-generic-hwe-18.04 5.0.0.32.89 linux-image-generic-lpae-hwe-18.04 5.0.0.32.89 linux-image-gke-5.0 5.0.0.1023.12 linux-image-lowlatency-hwe-18.04 5.0.0.32.89 linux-image-snapdragon-hwe-18.04 5.0.0.32.89 linux-image-virtual-hwe-18.04 5.0.0.32.89
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well. 8) - aarch64, noarch, ppc64le, s390x, x86_64

A local attacker could possibly use this to cause a\ndenial of service (system crash). (CVE-2016-10905)\n\nIt was discovered that a use-after-free error existed in the block layer\nsubsystem of the Linux kernel when certain failure conditions occurred. (CVE-2018-20856)\n\nIt was discovered that the USB gadget Midi driver in the Linux kernel\ncontained a double-free vulnerability when handling certain error\nconditions. A local attacker could use this to cause a denial of service\n(system crash). (CVE-2018-20961)\n\nIt was discovered that the XFS file system in the Linux kernel did not\nproperly handle mount failures in some situations. (CVE-2018-20976)\n\nIt was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not\ndid not handle detach operations correctly, leading to a use-after-free\nvulnerability. A physically proximate attacker could use this to cause a\ndenial of service (system crash) or possibly execute arbitrary code. \n(CVE-2018-21008)\n\nIt was discovered that the Intel Wi-Fi device driver in the Linux kernel\ndid not properly validate certain Tunneled Direct Link Setup (TDLS). A\nphysically proximate attacker could use this to cause a denial of service\n(Wi-Fi disconnect). (CVE-2019-0136)\n\nIt was discovered that the Linux kernel on ARM processors allowed a tracing\nprocess to modify a syscall after a seccomp decision had been made on that\nsyscall. A local attacker could possibly use this to bypass seccomp\nrestrictions. (CVE-2019-2054)\n\nIt was discovered that an integer overflow existed in the Binder\nimplementation of the Linux kernel, leading to a buffer overflow. A local\nattacker could use this to escalate privileges. (CVE-2019-2181)\n\nIt was discovered that the Marvell Wireless LAN device driver in the Linux\nkernel did not properly validate the BSS descriptor. (CVE-2019-10126)\n\nIt was discovered that the Bluetooth UART implementation in the Linux\nkernel did not properly check for missing tty operations. A local attacker\ncould use this to cause a denial of service. (CVE-2019-10207)\n\nJonathan Looney discovered that an integer overflow existed in the Linux\nkernel when handling TCP Selective Acknowledgments (SACKs). A remote\nattacker could use this to cause a denial of service (system crash). \n(CVE-2019-11477)\n\nJonathan Looney discovered that the TCP retransmission queue implementation\nin the Linux kernel could be fragmented when handling certain TCP Selective\nAcknowledgment (SACK) sequences. A remote attacker could use this to cause\na denial of service. (CVE-2019-11478)\n\nIt was discovered that the ext4 file system implementation in the Linux\nkernel did not properly zero out memory in some situations. A local\nattacker could use this to expose sensitive information (kernel memory). \n(CVE-2019-11833)\n\nIt was discovered that the PowerPC dlpar implementation in the Linux kernel\ndid not properly check for allocation errors in some situations. A local\nattacker could possibly use this to cause a denial of service (system\ncrash). (CVE-2019-12614)\n\nIt was discovered that the floppy driver in the Linux kernel did not\nproperly validate meta data, leading to a buffer overread. A local attacker\ncould use this to cause a denial of service (system crash). \n(CVE-2019-14283)\n\nIt was discovered that the floppy driver in the Linux kernel did not\nproperly validate ioctl() calls, leading to a division-by-zero. A local\nattacker could use this to cause a denial of service (system crash). \n(CVE-2019-14284)\n\nWen Huang discovered that the Marvell Wi-Fi device driver in the Linux\nkernel did not properly perform bounds checking, leading to a heap\noverflow. (CVE-2019-14814)\n\nWen Huang discovered that the Marvell Wi-Fi device driver in the Linux\nkernel did not properly perform bounds checking, leading to a heap\noverflow. (CVE-2019-14815)\n\nWen Huang discovered that the Marvell Wi-Fi device driver in the Linux\nkernel did not properly perform bounds checking, leading to a heap\noverflow. (CVE-2019-14816)\n\nMatt Delco discovered that the KVM hypervisor implementation in the Linux\nkernel did not properly perform bounds checking when handling coalesced\nMMIO write operations. A local attacker with write access to /dev/kvm could\nuse this to cause a denial of service (system crash).

Most systems should run the SMP kernel (if they can)\nregardless of the number of cores the CPU has. If you aren\u0027t sure which\nkernel you are running, run \"uname -a\". If you see SMP there, you are\nrunning the SMP kernel and should use the 4.4.199-smp version when running\nmkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit\nsystems should always use 4.4.199 as the version. \n\nIf you are using lilo or elilo to boot the machine, you\u0027ll need to ensure\nthat the machine is properly prepared before rebooting. \n\nIf using LILO:\nBy default, lilo.conf contains an image= line that references a symlink\nthat always points to the correct kernel. No editing should be required\nunless your machine uses a custom lilo.conf. If that is the case, be sure\nthat the image= line references the correct kernel file. Either way,\nyou\u0027ll need to run \"lilo\" as root to reinstall the boot loader. \n\nIf using elilo:\nEnsure that the /boot/vmlinuz symlink is pointing to the kernel you wish\nto use, and then run eliloconfig to update the EFI System Partition. \n\n\n+-----+\n\nSlackware Linux Security Team\nhttp://slackware.com/gpg-key\nsecurity@slackware.com\n\n+------------------------------------------------------------------------+\n| To leave the slackware-security mailing list: |\n+------------------------------------------------------------------------+\n| Send an email to majordomo@slackware.com with this text in the body of |\n| the email message: |\n| |\n| unsubscribe slackware-security |\n| |\n| You will get a confirmation message back containing instructions to |\n| complete the process.

Vulnerability from variot
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free. Linux Kernel Contains a race condition vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
[slackware-security] Slackware 14.2 kernel (SSA:2020-008-01)
New kernel packages are available for Slackware 14.2 to fix security issues.
Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/linux-4.4.208/: Upgraded. IPV6_MULTIPLE_TABLES n -> y +IPV6_SUBTREES y These updates fix various bugs and security issues. Be sure to upgrade your initrd after upgrading the kernel packages. If you use lilo to boot your machine, be sure lilo.conf points to the correct kernel and initrd and run lilo as root to update the bootloader. If you use elilo to boot your machine, you should run eliloconfig to copy the kernel and initrd to the EFI System Partition.

Installation instructions: +------------------------+
Upgrade the packages as root:
upgradepkg kernel-*.txz
If you are using an initrd, you'll need to rebuild it.
For a 32-bit SMP machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2):
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.208-smp | bash
For a 64-bit machine, or a 32-bit uniprocessor machine, use this command (substitute the appropriate kernel version if you are not running Slackware 14.2):
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 4.4.208 | bash
Please note that "uniprocessor" has to do with the kernel you are running, not with the CPU. Most systems should run the SMP kernel (if they can) regardless of the number of cores the CPU has. If you aren't sure which kernel you are running, run "uname -a". If you see SMP there, you are running the SMP kernel and should use the 4.4.208-smp version when running mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit systems should always use 4.4.208 as the version.
If you are using lilo or elilo to boot the machine, you'll need to ensure that the machine is properly prepared before rebooting.
If using LILO: By default, lilo.conf contains an image= line that references a symlink that always points to the correct kernel. No editing should be required unless your machine uses a custom lilo.conf. If that is the case, be sure that the image= line references the correct kernel file. Either way, you'll need to run "lilo" as root to reinstall the boot loader.
If using elilo: Ensure that the /boot/vmlinuz symlink is pointing to the kernel you wish to use, and then run eliloconfig to update the EFI System Partition.

It was discovered that the Atheros 802.11ac wireless USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15099)
It was discovered that the HSA Linux kernel driver for AMD GPU devices did not properly check for errors in certain situations, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service. (CVE-2019-16229)
It was discovered that the Marvell 8xxx Libertas WLAN device driver in the Linux kernel did not properly check for errors in certain situations, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service. An attacker with write access to /dev/video0 on a system with the vivid module loaded could possibly use this to gain administrative privileges. (CVE-2019-18683)
It was discovered that the Renesas Digital Radio Interface (DRIF) driver in the Linux kernel did not properly initialize data. A local attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2019-18786)
It was discovered that the Afatech AF9005 DVB-T USB device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-18809)
It was discovered that the btrfs file system in the Linux kernel did not properly validate metadata, leading to a NULL pointer dereference. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19057)
It was discovered that the crypto subsystem in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19062)

It was discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle ioctl requests to get emulated CPUID features. An attacker with access to /dev/kvm could use this to cause a denial of service (system crash). An attacker could use this to specially craft an ext4 file system that, when mounted, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-19767)
Gao Chuan discovered that the SAS Class driver in the Linux kernel contained a race condition that could lead to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-19965)
It was discovered that the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly deallocate memory in certain error conditions. An attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-20096)
Mitchell Frank discovered that the Wi-Fi implementation in the Linux kernel when used as an access point would send IAPP location updates for stations before client authentication had completed. A physically proximate attacker could use this to cause a denial of service. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-7053)
It was discovered that the B2C2 FlexCop USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15291)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 ESM: linux-image-4.15.0-1069-azure 4.15.0-1069.74~14.04.1 linux-image-azure 4.15.0.1069.55
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

"data": "An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free. Linux Kernel Contains a race condition vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. \n-----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n[slackware-security] Slackware 14.2 kernel (SSA:2020-008-01)\n\nNew kernel packages are available for Slackware 14.2 to fix security issues. \n\n\nHere are the details from the Slackware 14.2 ChangeLog:\n+--------------------------+\npatches/packages/linux-4.4.208/*: Upgraded. \n IPV6_MULTIPLE_TABLES n -\u003e y\n +IPV6_SUBTREES y\n These updates fix various bugs and security issues. \n Be sure to upgrade your initrd after upgrading the kernel packages. \n If you use lilo to boot your machine, be sure lilo.conf points to the correct\n kernel and initrd and run lilo as root to update the bootloader. \n If you use elilo to boot your machine, you should run eliloconfig to copy the\n kernel and initrd to the EFI System Partition. \n For more information, see:\n Fixed in 4.4.203:\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19524\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-15917\n Fixed in 4.4.204:\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-18660\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-15291\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-18683\n Fixed in 4.4.206:\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-12614\n Fixed in 4.4.207:\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19227\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19062\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19338\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19332\n Fixed in 4.4.208:\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19057\n https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-19063\n (* Security fix *)\n+--------------------------+\n\n\nWhere to find the new packages:\n+-----------------------------+\n\nThanks to the friendly folks at the OSU Open Source Lab\n(http://osuosl.org) for donating FTP and rsync hosting\nto the Slackware project!

Most systems should run the SMP kernel (if they can)\nregardless of the number of cores the CPU has. If you aren\u0027t sure which\nkernel you are running, run \"uname -a\". If you see SMP there, you are\nrunning the SMP kernel and should use the 4.4.208-smp version when running\nmkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit\nsystems should always use 4.4.208 as the version. \n\nIf you are using lilo or elilo to boot the machine, you\u0027ll need to ensure\nthat the machine is properly prepared before rebooting. \n\nIf using LILO:\nBy default, lilo.conf contains an image= line that references a symlink\nthat always points to the correct kernel. No editing should be required\nunless your machine uses a custom lilo.conf. If that is the case, be sure\nthat the image= line references the correct kernel file. Either way,\nyou\u0027ll need to run \"lilo\" as root to reinstall the boot loader. \n\nIf using elilo:\nEnsure that the /boot/vmlinuz symlink is pointing to the kernel you wish\nto use, and then run eliloconfig to update the EFI System Partition. \n\n\n+-----+\n\nSlackware Linux Security Team\nhttp://slackware.com/gpg-key\nsecurity@slackware.com\n\n+------------------------------------------------------------------------+\n| To leave the slackware-security mailing list: |\n+------------------------------------------------------------------------+\n| Send an email to majordomo@slackware.com with this text in the body of |\n| the email message: |\n| |\n| unsubscribe slackware-security |\n| |\n| You will get a confirmation message back containing instructions to |\n| complete the process.

A locking inconsistency issue was discovered in the tty subsystem of the Linux kernel through 5.9.13. drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c may allow a read-after-free attack against TIOCGSID, aka CID-c8bcd9c5be24. Vendors must CID-c8bcd9c5be24 It is published as.Information may be obtained. Bugs fixed (https://bugzilla.redhat.com/):
2030932 - CVE-2021-44228 log4j-core: Remote code execution in Log4j 2.x when logs contain an attacker-controlled string value
- ========================================================================== Ubuntu Security Notice USN-4752-1 February 25, 2021
linux-oem-5.6 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-oem-5.6: Linux kernel for OEM systems
Details:
Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered that legacy pairing and secure-connections pairing authentication in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. A physically proximate attacker could use this to impersonate a previously paired Bluetooth device. (CVE-2020-10135)
Jay Shin discovered that the ext4 file system implementation in the Linux kernel did not properly handle directory access with broken indexing, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-14314)
It was discovered that the block layer implementation in the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-15436)
It was discovered that the serial port driver in the Linux kernel did not properly initialize a pointer in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2020-15437)
Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-24490)
It was discovered that the NFS client implementation in the Linux kernel did not properly perform bounds checking before copying security labels in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)
It was discovered that the Rados block device (rbd) driver in the Linux kernel did not properly perform privilege checks for access to rbd devices in some situations. A local attacker could use this to map or unmap rbd block devices. A local attacker could use this to cause a denial of service. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. A privileged attacker could use this to cause a denial of service (kernel memory exhaustion). A local attacker in a guest VM could possibly use this to cause a denial of service (host system crash). A local attacker could use this to possibly cause a denial of service (system crash). A local attacker could use this to expose sensitive information (kernel memory). (CVE-2020-28588)
It was discovered that the framebuffer implementation in the Linux kernel did not properly perform range checks in certain situations. A local attacker could use this to expose sensitive information (kernel memory). A local attacker could use this to gain unintended write access to read-only memory pages. (CVE-2020-29368)
Jann Horn discovered that the mmap implementation in the Linux kernel contained a race condition when handling munmap() operations, leading to a read-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-29369)
Jann Horn discovered that the romfs file system in the Linux kernel did not properly validate file system meta-data, leading to an out-of-bounds read. An attacker could use this to construct a malicious romfs image that, when mounted, exposed sensitive information (kernel memory). A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-29661)
It was discovered that a race condition existed that caused the Linux kernel to not properly restrict exit signal delivery. A local attacker could possibly use this to send signals to arbitrary processes. (CVE-2020-35508)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: linux-image-5.6.0-1048-oem 5.6.0-1048.52 linux-image-oem-20.04 5.6.0.1048.44
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
CVE-2020-27825
Adam 'pi3' Zabrocki reported a use-after-free flaw in the ftrace
ring buffer resizing logic due to a race condition, which could
result in denial of service or information leak.
CVE-2020-27830
Shisong Qin reported a NULL pointer dereference flaw in the Speakup
screen reader core driver.
CVE-2020-28374
David Disseldorp discovered that the LIO SCSI target implementation
performed insufficient checking in certain XCOPY requests. An
attacker with access to a LUN and knowledge of Unit Serial Number
assignments can take advantage of this flaw to read and write to any
LIO backstore, regardless of the SCSI transport settings.
CVE-2020-29568 (XSA-349)
Michael Kurth and Pawel Wieczorkiewicz reported that frontends can
trigger OOM in backends by updating a watched path. A
misbehaving guest can trigger a dom0 crash by continuously
connecting / disconnecting a block frontend.
CVE-2020-36158
A buffer overflow flaw was discovered in the mwifiex WiFi driver
which could result in denial of service or the execution of
arbitrary code via a long SSID value. A privileged user (with root or CAP_NET_ADMIN) can
take advantage of this flaw to cause a kernel panic when inserting
iptables rules.
For the stable distribution (buster), these problems have been fixed in version 4.19.171-2.
We recommend that you upgrade your linux packages.

Bugs fixed (https://bugzilla.redhat.com/):\n\n2030932 - CVE-2021-44228 log4j-core: Remote code execution in Log4j 2.x when logs contain an attacker-controlled string value\n\n5. ==========================================================================\nUbuntu Security Notice USN-4752-1\nFebruary 25, 2021\n\nlinux-oem-5.6 vulnerabilities\n==========================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 20.04 LTS\n\nSummary:\n\nSeveral security issues were fixed in the Linux kernel. \n\nSoftware Description:\n- linux-oem-5.6: Linux kernel for OEM systems\n\nDetails:\n\nDaniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered\nthat legacy pairing and secure-connections pairing authentication in the\nBluetooth protocol could allow an unauthenticated user to complete\nauthentication without pairing credentials via adjacent access. A\nphysically proximate attacker could use this to impersonate a previously\npaired Bluetooth device. (CVE-2020-10135)\n\nJay Shin discovered that the ext4 file system implementation in the Linux\nkernel did not properly handle directory access with broken indexing,\nleading to an out-of-bounds read vulnerability. A local attacker could use\nthis to cause a denial of service (system crash). (CVE-2020-14314)\n\nIt was discovered that the block layer implementation in the Linux kernel\ndid not properly perform reference counting in some situations, leading to\na use-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash). (CVE-2020-15436)\n\nIt was discovered that the serial port driver in the Linux kernel did not\nproperly initialize a pointer in some situations. A local attacker could\npossibly use this to cause a denial of service (system crash). \n(CVE-2020-15437)\n\nAndy Nguyen discovered that the Bluetooth HCI event packet parser in the\nLinux kernel did not properly handle event advertisements of certain sizes,\nleading to a heap-based buffer overflow. A physically proximate remote\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2020-24490)\n\nIt was discovered that the NFS client implementation in the Linux kernel\ndid not properly perform bounds checking before copying security labels in\nsome situations. A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. (CVE-2020-25212)\n\nIt was discovered that the Rados block device (rbd) driver in the Linux\nkernel did not properly perform privilege checks for access to rbd devices\nin some situations. A local attacker could use this to map or unmap rbd\nblock devices. A local attacker could use this\nto cause a denial of service. A local attacker could use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. A privileged attacker\ncould use this to cause a denial of service (kernel memory exhaustion). A local attacker in a\nguest VM could possibly use this to cause a denial of service (host system\ncrash). A local attacker\ncould use this to possibly cause a denial of service (system crash). A local attacker\ncould use this to expose sensitive information (kernel memory). \n(CVE-2020-28588)\n\nIt was discovered that the framebuffer implementation in the Linux kernel\ndid not properly perform range checks in certain situations. A local\nattacker could use this to expose sensitive information (kernel memory). A local attacker could use\nthis to gain unintended write access to read-only memory pages. \n(CVE-2020-29368)\n\nJann Horn discovered that the mmap implementation in the Linux kernel\ncontained a race condition when handling munmap() operations, leading to a\nread-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash) or possibly expose sensitive information. \n(CVE-2020-29369)\n\nJann Horn discovered that the romfs file system in the Linux kernel did not\nproperly validate file system meta-data, leading to an out-of-bounds read. \nAn attacker could use this to construct a malicious romfs image that, when\nmounted, exposed sensitive information (kernel memory). A local attacker could use this to cause a denial of service\n(system crash) or possibly expose sensitive information (kernel memory). A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. (CVE-2020-29661)\n\nIt was discovered that a race condition existed that caused the Linux\nkernel to not properly restrict exit signal delivery. A local attacker\ncould possibly use this to send signals to arbitrary processes. \n(CVE-2020-35508)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 20.04 LTS:\n linux-image-5.6.0-1048-oem 5.6.0-1048.52\n linux-image-oem-20.04 5.6.0.1048.44\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. \n\nReferences:\n https://usn.ubuntu.com/4752-1\n CVE-2020-10135, CVE-2020-14314, CVE-2020-15436, CVE-2020-15437,\n CVE-2020-24490, CVE-2020-25212, CVE-2020-25284, CVE-2020-25641,\n CVE-2020-25643, CVE-2020-25704, CVE-2020-27152, CVE-2020-27815,\n CVE-2020-28588, CVE-2020-28915, CVE-2020-29368, CVE-2020-29369,\n CVE-2020-29371, CVE-2020-29660, CVE-2020-29661, CVE-2020-35508\n\nPackage Information:\n https://launchpad.net/ubuntu/+source/linux-oem-5.6/5.6.0-1048.52\n.

An\n attacker with access to a LUN and knowledge of Unit Serial Number\n assignments can take advantage of this flaw to read and write to any\n LIO backstore, regardless of the SCSI transport settings. \n\nCVE-2020-29568 (XSA-349)\n\n Michael Kurth and Pawel Wieczorkiewicz reported that frontends can\n trigger OOM in backends by updating a watched path. A\n misbehaving guest can trigger a dom0 crash by continuously\n connecting / disconnecting a block frontend. \n\nCVE-2020-36158\n\n A buffer overflow flaw was discovered in the mwifiex WiFi driver\n which could result in denial of service or the execution of\n arbitrary code via a long SSID value. A privileged user (with root or CAP_NET_ADMIN) can\n take advantage of this flaw to cause a kernel panic when inserting\n iptables rules. \n\nFor the stable distribution (buster), these problems have been fixed in\nversion 4.19.171-2. \n\nWe recommend that you upgrade your linux packages. \n\nFor the detailed security status of linux please refer to its security\ntracker page at:\nhttps://security-tracker.debian.org/tracker/linux\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nj3wO/r/1gut/bK/OJnjmOB9J5OXP+cHxYtrhPqXFy2Hzkgj1CRU=\n=u23W\n-----END PGP SIGNATURE-----\n",

- ========================================================================== Ubuntu Security Notice USN-4752-1 February 25, 2021
linux-oem-5.6 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux-oem-5.6: Linux kernel for OEM systems
Details:
Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered that legacy pairing and secure-connections pairing authentication in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. A physically proximate attacker could use this to impersonate a previously paired Bluetooth device. (CVE-2020-10135)
Jay Shin discovered that the ext4 file system implementation in the Linux kernel did not properly handle directory access with broken indexing, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-14314)
It was discovered that the block layer implementation in the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-15436)
It was discovered that the serial port driver in the Linux kernel did not properly initialize a pointer in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2020-15437)
Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-24490)
It was discovered that the NFS client implementation in the Linux kernel did not properly perform bounds checking before copying security labels in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)
It was discovered that the Rados block device (rbd) driver in the Linux kernel did not properly perform privilege checks for access to rbd devices in some situations. A local attacker could use this to map or unmap rbd block devices. (CVE-2020-25284)
It was discovered that the block layer subsystem in the Linux kernel did not properly handle zero-length requests. A local attacker could use this to cause a denial of service. (CVE-2020-25641)
It was discovered that the HDLC PPP implementation in the Linux kernel did not properly validate input in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-25643)
Kiyin (尹亮) discovered that the perf subsystem in the Linux kernel did not properly deallocate memory in some situations. A privileged attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2020-25704)
It was discovered that the KVM hypervisor in the Linux kernel did not properly handle interrupts in certain situations. A local attacker in a guest VM could possibly use this to cause a denial of service (host system crash). (CVE-2020-27152)
It was discovered that the jfs file system implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to possibly cause a denial of service (system crash). (CVE-2020-27815)
It was discovered that an information leak existed in the syscall implementation in the Linux kernel on 32 bit systems. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2020-28588)
It was discovered that the framebuffer implementation in the Linux kernel did not properly perform range checks in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2020-28915)
Jann Horn discovered a race condition in the copy-on-write implementation in the Linux kernel when handling hugepages. A local attacker could use this to gain unintended write access to read-only memory pages. (CVE-2020-29368)
Jann Horn discovered that the mmap implementation in the Linux kernel contained a race condition when handling munmap() operations, leading to a read-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-29369)
Jann Horn discovered that the romfs file system in the Linux kernel did not properly validate file system meta-data, leading to an out-of-bounds read. An attacker could use this to construct a malicious romfs image that, when mounted, exposed sensitive information (kernel memory). (CVE-2020-29371)
Jann Horn discovered that the tty subsystem of the Linux kernel did not use consistent locking in some situations, leading to a read-after-free vulnerability. (CVE-2020-29660)
Jann Horn discovered a race condition in the tty subsystem of the Linux kernel in the locking for the TIOCSPGRP ioctl(), leading to a use-after- free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-29661)
It was discovered that a race condition existed that caused the Linux kernel to not properly restrict exit signal delivery. A local attacker could possibly use this to send signals to arbitrary processes. (CVE-2020-35508)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: linux-image-5.6.0-1048-oem 5.6.0-1048.52 linux-image-oem-20.04 5.6.0.1048.44
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.

A\nphysically proximate attacker could use this to impersonate a previously\npaired Bluetooth device. (CVE-2020-10135)\n\nJay Shin discovered that the ext4 file system implementation in the Linux\nkernel did not properly handle directory access with broken indexing,\nleading to an out-of-bounds read vulnerability. A local attacker could use\nthis to cause a denial of service (system crash). (CVE-2020-14314)\n\nIt was discovered that the block layer implementation in the Linux kernel\ndid not properly perform reference counting in some situations, leading to\na use-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash). (CVE-2020-15436)\n\nIt was discovered that the serial port driver in the Linux kernel did not\nproperly initialize a pointer in some situations. A local attacker could\npossibly use this to cause a denial of service (system crash). \n(CVE-2020-15437)\n\nAndy Nguyen discovered that the Bluetooth HCI event packet parser in the\nLinux kernel did not properly handle event advertisements of certain sizes,\nleading to a heap-based buffer overflow. A physically proximate remote\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2020-24490)\n\nIt was discovered that the NFS client implementation in the Linux kernel\ndid not properly perform bounds checking before copying security labels in\nsome situations. A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. (CVE-2020-25212)\n\nIt was discovered that the Rados block device (rbd) driver in the Linux\nkernel did not properly perform privilege checks for access to rbd devices\nin some situations. A local attacker could use this to map or unmap rbd\nblock devices. (CVE-2020-25284)\n\nIt was discovered that the block layer subsystem in the Linux kernel did\nnot properly handle zero-length requests. A local attacker could use this\nto cause a denial of service. (CVE-2020-25641)\n\nIt was discovered that the HDLC PPP implementation in the Linux kernel did\nnot properly validate input in some situations. A local attacker could use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2020-25643)\n\nKiyin (\u5c39\u4eae) discovered that the perf subsystem in the Linux kernel did\nnot properly deallocate memory in some situations. A privileged attacker\ncould use this to cause a denial of service (kernel memory exhaustion). \n(CVE-2020-25704)\n\nIt was discovered that the KVM hypervisor in the Linux kernel did not\nproperly handle interrupts in certain situations. A local attacker in a\nguest VM could possibly use this to cause a denial of service (host system\ncrash). (CVE-2020-27152)\n\nIt was discovered that the jfs file system implementation in the Linux\nkernel contained an out-of-bounds read vulnerability. A local attacker\ncould use this to possibly cause a denial of service (system crash). \n(CVE-2020-27815)\n\nIt was discovered that an information leak existed in the syscall\nimplementation in the Linux kernel on 32 bit systems. A local attacker\ncould use this to expose sensitive information (kernel memory). \n(CVE-2020-28588)\n\nIt was discovered that the framebuffer implementation in the Linux kernel\ndid not properly perform range checks in certain situations. A local\nattacker could use this to expose sensitive information (kernel memory). \n(CVE-2020-28915)\n\nJann Horn discovered a race condition in the copy-on-write implementation\nin the Linux kernel when handling hugepages. A local attacker could use\nthis to gain unintended write access to read-only memory pages. \n(CVE-2020-29368)\n\nJann Horn discovered that the mmap implementation in the Linux kernel\ncontained a race condition when handling munmap() operations, leading to a\nread-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash) or possibly expose sensitive information. \n(CVE-2020-29369)\n\nJann Horn discovered that the romfs file system in the Linux kernel did not\nproperly validate file system meta-data, leading to an out-of-bounds read. \nAn attacker could use this to construct a malicious romfs image that, when\nmounted, exposed sensitive information (kernel memory). (CVE-2020-29371)\n\nJann Horn discovered that the tty subsystem of the Linux kernel did not use\nconsistent locking in some situations, leading to a read-after-free\nvulnerability. \n(CVE-2020-29660)\n\nJann Horn discovered a race condition in the tty subsystem of the Linux\nkernel in the locking for the TIOCSPGRP ioctl(), leading to a use-after-\nfree vulnerability. A local attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. (CVE-2020-29661)\n\nIt was discovered that a race condition existed that caused the Linux\nkernel to not properly restrict exit signal delivery. A local attacker\ncould possibly use this to send signals to arbitrary processes. \n(CVE-2020-35508)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 20.04 LTS:\n linux-image-5.6.0-1048-oem 5.6.0-1048.52\n linux-image-oem-20.04 5.6.0.1048.44\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nATTENTION: Due to an unavoidable ABI change the kernel updates have\nbeen given a new version number, which requires you to recompile and\nreinstall all third party kernel modules you might have installed. \nUnless you manually uninstalled the standard kernel metapackages\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,\nlinux-powerpc), a standard system upgrade will automatically perform\nthis as well. \n\nReferences:\n https://usn.ubuntu.com/4752-1\n CVE-2020-10135, CVE-2020-14314, CVE-2020-15436, CVE-2020-15437,\n CVE-2020-24490, CVE-2020-25212, CVE-2020-25284, CVE-2020-25641,\n CVE-2020-25643, CVE-2020-25704, CVE-2020-27152, CVE-2020-27815,\n CVE-2020-28588, CVE-2020-28915, CVE-2020-29368, CVE-2020-29369,\n CVE-2020-29371, CVE-2020-29660, CVE-2020-29661, CVE-2020-35508\n\nPackage Information:\n https://launchpad.net/ubuntu/+source/linux-oem-5.6/5.6.0-1048.52\n",
