Summary
In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash.

Vulnerability from variot
In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash. Dnsmasq versions 2.77 and earlier contains multiple vulnerabilities. dnsmasq Contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Multiple Siemens SCALANCE Products are prone to the following security vulnerabilities: 1. A buffer-overflow vulnerability 2. Multiple denial-of-service vulnerabilities Attackers can exploit these issues to execute arbitrary code within the context of affected device or cause a denial-of-service condition. This BID is being retired as a duplicate of BID 101085 Dnsmasq VU#973527 Multiple Security Vulnerabilities

var-201602-0391
Vulnerability from variot
The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 does not properly limit CNAME resolution, which allows remote attackers to cause a denial of service (worker process resource consumption) via vectors related to arbitrary name resolution. nginx is prone to multiple denial-of-service vulnerabilities. Attackers can exploit these issues to cause denial-of-service conditions. There is a security vulnerability in the resolver of nginx versions prior to 1.8.1 and versions 1.9.x prior to 1.9.10. The vulnerability stems from the fact that the program does not limit CNAME resolution. These only affect nginx if the "resolver" directive is used in a configuration file.
For the oldstable distribution (wheezy), these problems have been fixed in version 1.2.1-2.2+wheezy4.
For the stable distribution (jessie), these problems have been fixed in version 1.6.2-5+deb8u1.
For the testing distribution (stretch), these problems have been fixed in version 1.9.10-1.
For the unstable distribution (sid), these problems have been fixed in version 1.9.10-1.
We recommend that you upgrade your nginx packages. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

- Description:
Nginx is a web and proxy server with a focus on high concurrency, performance, and low memory usage.
The following packages have been upgraded to a newer upstream version: rh-nginx18-nginx (1.8.1).
Security Fix(es):
-
A NULL pointer dereference flaw was found in the nginx code responsible for saving client request body to a temporary file. A remote attacker could send a specially crafted request that would cause nginx worker process to crash. (CVE-2016-4450)
-
It was discovered that nginx could perform an out of bound read and dereference an invalid pointer when resolving CNAME DNS records. An attacker able to manipulate DNS responses received by nginx could use this flaw to cause a worker process to crash if nginx enabled the resolver in its configuration. (CVE-2016-0742)
-
A use-after-free flaw was found in the way nginx resolved certain CNAME DNS records. (CVE-2016-0746)
-
It was discovered that nginx did not limit recursion when resolving CNAME DNS records. (CVE-2016-0747)
-
Solution:
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
The rh-nginx18-nginx service must be restarted for this update to take effect.

"data": "The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 does not properly limit CNAME resolution, which allows remote attackers to cause a denial of service (worker process resource consumption) via vectors related to arbitrary name resolution. nginx is prone to multiple denial-of-service vulnerabilities. \nAttackers can exploit these issues to cause denial-of-service conditions. There is a security vulnerability in the resolver of nginx versions prior to 1.8.1 and versions 1.9.x prior to 1.9.10. The vulnerability stems from the fact that the program does not limit CNAME resolution. These only affect nginx if\nthe \"resolver\" directive is used in a configuration file. \n\nFor the oldstable distribution (wheezy), these problems have been fixed\nin version 1.2.1-2.2+wheezy4. \n\nFor the stable distribution (jessie), these problems have been fixed in\nversion 1.6.2-5+deb8u1. \n\nFor the testing distribution (stretch), these problems have been fixed\nin version 1.9.10-1. \n\nFor the unstable distribution (sid), these problems have been fixed in\nversion 1.9.10-1. \n\nWe recommend that you upgrade your nginx packages. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Moderate: rh-nginx18-nginx security update\nAdvisory ID: RHSA-2016:1425-01\nProduct: Red Hat Software Collections\nAdvisory URL: https://access.redhat.com/errata/RHSA-2016:1425\nIssue date: 2016-07-14\nCVE Names: CVE-2016-0742 CVE-2016-0746 CVE-2016-0747 \n CVE-2016-4450 \n=====================================================================\n\n1. Summary:\n\nAn update for rh-nginx18-nginx is now available for Red Hat Software\nCollections. \n\nRed Hat Product Security has rated this update as having a security impact\nof Moderate. A Common Vulnerability Scoring System (CVSS) base score, which\ngives a detailed severity rating, is available for each vulnerability from\nthe CVE link(s) in the References section. \n\n2.

Description:\n\nNginx is a web and proxy server with a focus on high concurrency,\nperformance, and low memory usage. \n\nThe following packages have been upgraded to a newer upstream version:\nrh-nginx18-nginx (1.8.1). \n\nSecurity Fix(es):\n\n* A NULL pointer dereference flaw was found in the nginx code responsible\nfor saving client request body to a temporary file. A remote attacker could\nsend a specially crafted request that would cause nginx worker process to\ncrash. (CVE-2016-4450)\n\n* It was discovered that nginx could perform an out of bound read and\ndereference an invalid pointer when resolving CNAME DNS records. An\nattacker able to manipulate DNS responses received by nginx could use this\nflaw to cause a worker process to crash if nginx enabled the resolver in\nits configuration. (CVE-2016-0742)\n\n* A use-after-free flaw was found in the way nginx resolved certain CNAME\nDNS records. \n(CVE-2016-0746)\n\n* It was discovered that nginx did not limit recursion when resolving CNAME\nDNS records. \n(CVE-2016-0747)\n\n4. Solution:\n\nFor details on how to apply this update, which includes the changes\ndescribed in this advisory, refer to:\n\nhttps://access.redhat.com/articles/11258\n\nThe rh-nginx18-nginx service must be restarted for this update to take\neffect. \n\n5.

Vulnerability from variot
dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests. Dnsmasq versions 2.77 and earlier contains multiple vulnerabilities. dnsmasq Contains an information disclosure vulnerability.Information may be obtained. Attackers can exploit these issues to execute arbitrary code within the context of the affected application, bypass the ASLR, gain sensitive information, or cause a denial-of-service condition. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
===================================================================== Red Hat Security Advisory
Synopsis: Critical: dnsmasq security update Advisory ID: RHSA-2017:2836-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2836 Issue date: 2017-10-02 CVE Names: CVE-2017-14491 CVE-2017-14492 CVE-2017-14493 CVE-2017-14494 CVE-2017-14495 CVE-2017-14496 =====================================================================
- Summary:
An update for dnsmasq is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
- Relevant releases/architectures:
Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64
- Description:
The dnsmasq packages contain Dnsmasq, a lightweight DNS (Domain Name Server) forwarder and DHCP (Dynamic Host Configuration Protocol) server.
Security Fix(es):
-
A heap buffer overflow was found in dnsmasq in the code responsible for building DNS replies. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. (CVE-2017-14491)
-
A heap buffer overflow was discovered in dnsmasq in the IPv6 router advertisement (RA) handling code. An attacker on the local network segment could send crafted RAs to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. This issue only affected configurations using one of these options: enable-ra, ra-only, slaac, ra-names, ra-advrouter, or ra-stateless. (CVE-2017-14492)
-
A stack buffer overflow was found in dnsmasq in the DHCPv6 code. An attacker on the local network could send a crafted DHCPv6 request to dnsmasq which would cause it to a crash or, potentially, execute arbitrary code. (CVE-2017-14493)
-
An information leak was found in dnsmasq in the DHCPv6 relay code. An attacker on the local network could send crafted DHCPv6 packets to dnsmasq causing it to forward the contents of process memory, potentially leaking sensitive data. (CVE-2017-14494)
-
A memory exhaustion flaw was found in dnsmasq in the EDNS0 code. An attacker could send crafted DNS packets which would trigger memory allocations which would never be freed, leading to unbounded memory consumption and eventually a crash. This issue only affected configurations using one of the options: add-mac, add-cpe-id, or add-subnet. (CVE-2017-14495)
-
An integer underflow flaw leading to a buffer over-read was found in dnsmasq in the EDNS0 code. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash. This issue only affected configurations using one of the options: add-mac, add-cpe-id, or add-subnet. (CVE-2017-14496)
Red Hat would like to thank Felix Wilhelm (Google Security Team), Fermin J. Serna (Google Security Team), Gabriel Campana (Google Security Team), Kevin Hamacher (Google Security Team), and Ron Bowes (Google Security Team) for reporting these issues.

Summary:\n\nAn update for dnsmasq is now available for Red Hat Enterprise Linux 7. \n\nRed Hat Product Security has rated this update as having a security impact\nof Critical. A Common Vulnerability Scoring System (CVSS) base score, which\ngives a detailed severity rating, is available for each vulnerability from\nthe CVE link(s) in the References section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux Client (v. 7) - x86_64\nRed Hat Enterprise Linux Client Optional (v. 7) - x86_64\nRed Hat Enterprise Linux ComputeNode (v. 7) - x86_64\nRed Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64\nRed Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64\nRed Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64\nRed Hat Enterprise Linux Workstation (v. 7) - x86_64\nRed Hat Enterprise Linux Workstation Optional (v. 7) - x86_64\n\n3. Description:\n\nThe dnsmasq packages contain Dnsmasq, a lightweight DNS (Domain Name\nServer) forwarder and DHCP (Dynamic Host Configuration Protocol) server. \n\nSecurity Fix(es):\n\n* A heap buffer overflow was found in dnsmasq in the code responsible for\nbuilding DNS replies. An attacker could send crafted DNS packets to dnsmasq\nwhich would cause it to crash or, potentially, execute arbitrary code. \n(CVE-2017-14491)\n\n* A heap buffer overflow was discovered in dnsmasq in the IPv6 router\nadvertisement (RA) handling code. An attacker on the local network segment\ncould send crafted RAs to dnsmasq which would cause it to crash or,\npotentially, execute arbitrary code. This issue only affected\nconfigurations using one of these options: enable-ra, ra-only, slaac,\nra-names, ra-advrouter, or ra-stateless. (CVE-2017-14492)\n\n* A stack buffer overflow was found in dnsmasq in the DHCPv6 code. An\nattacker on the local network could send a crafted DHCPv6 request to\ndnsmasq which would cause it to a crash or, potentially, execute arbitrary\ncode. (CVE-2017-14493)\n\n* An information leak was found in dnsmasq in the DHCPv6 relay code. An\nattacker on the local network could send crafted DHCPv6 packets to dnsmasq\ncausing it to forward the contents of process memory, potentially leaking\nsensitive data. (CVE-2017-14494)\n\n* A memory exhaustion flaw was found in dnsmasq in the EDNS0 code. An\nattacker could send crafted DNS packets which would trigger memory\nallocations which would never be freed, leading to unbounded memory\nconsumption and eventually a crash. This issue only affected configurations\nusing one of the options: add-mac, add-cpe-id, or add-subnet. \n(CVE-2017-14495)\n\n* An integer underflow flaw leading to a buffer over-read was found in\ndnsmasq in the EDNS0 code. An attacker could send crafted DNS packets to\ndnsmasq which would cause it to crash. This issue only affected\nconfigurations using one of the options: add-mac, add-cpe-id, or\nadd-subnet. (CVE-2017-14496)\n\nRed Hat would like to thank Felix Wilhelm (Google Security Team), Fermin J. \nSerna (Google Security Team), Gabriel Campana (Google Security Team), Kevin\nHamacher (Google Security Team), and Ron Bowes (Google Security Team) for\nreporting these issues. \n\n4.

Vulnerability from variot
Use-after-free vulnerability in the resolver in nginx 0.6.18 through 1.8.0 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (worker process crash) or possibly have unspecified other impact via a crafted DNS response related to CNAME response processing. Supplementary information : CWE Vulnerability type by CWE-416: Use-after-free ( Use of freed memory ) Has been identified. nginx is prone to multiple denial-of-service vulnerabilities. Attackers can exploit these issues to cause denial-of-service conditions. There is a use-after-free vulnerability in the resolver of nginx versions prior to 1.8.1 and versions 1.9.x prior to 1.9.10. These only affect nginx if the "resolver" directive is used in a configuration file.
For the oldstable distribution (wheezy), these problems have been fixed in version 1.2.1-2.2+wheezy4.
For the stable distribution (jessie), these problems have been fixed in version 1.6.2-5+deb8u1.
For the testing distribution (stretch), these problems have been fixed in version 1.9.10-1.
For the unstable distribution (sid), these problems have been fixed in version 1.9.10-1.
We recommend that you upgrade your nginx packages. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

"data": "Use-after-free vulnerability in the resolver in nginx 0.6.18 through 1.8.0 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (worker process crash) or possibly have unspecified other impact via a crafted DNS response related to CNAME response processing. Supplementary information : CWE Vulnerability type by CWE-416: Use-after-free ( Use of freed memory ) Has been identified. nginx is prone to multiple denial-of-service vulnerabilities. \nAttackers can exploit these issues to cause denial-of-service conditions. There is a use-after-free vulnerability in the resolver of nginx versions prior to 1.8.1 and versions 1.9.x prior to 1.9.10. These only affect nginx if\nthe \"resolver\" directive is used in a configuration file. \n\nFor the oldstable distribution (wheezy), these problems have been fixed\nin version 1.2.1-2.2+wheezy4. \n\nFor the stable distribution (jessie), these problems have been fixed in\nversion 1.6.2-5+deb8u1. \n\nFor the testing distribution (stretch), these problems have been fixed\nin version 1.9.10-1. \n\nFor the unstable distribution (sid), these problems have been fixed in\nversion 1.9.10-1. \n\nWe recommend that you upgrade your nginx packages. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Moderate: rh-nginx18-nginx security update\nAdvisory ID: RHSA-2016:1425-01\nProduct: Red Hat Software Collections\nAdvisory URL: https://access.redhat.com/errata/RHSA-2016:1425\nIssue date: 2016-07-14\nCVE Names: CVE-2016-0742 CVE-2016-0746 CVE-2016-0747 \n CVE-2016-4450 \n=====================================================================\n\n1.

Description:\n\nNginx is a web and proxy server with a focus on high concurrency,\nperformance, and low memory usage. \n\nThe following packages have been upgraded to a newer upstream version:\nrh-nginx18-nginx (1.8.1). \n\nSecurity Fix(es):\n\n* A NULL pointer dereference flaw was found in the nginx code responsible\nfor saving client request body to a temporary file. (CVE-2016-4450)\n\n* It was discovered that nginx could perform an out of bound read and\ndereference an invalid pointer when resolving CNAME DNS records. (CVE-2016-0742)\n\n* A use-after-free flaw was found in the way nginx resolved certain CNAME\nDNS records. \n(CVE-2016-0746)\n\n* It was discovered that nginx did not limit recursion when resolving CNAME\nDNS records. \n(CVE-2016-0747)\n\n4. Solution:\n\nFor details on how to apply this update, which includes the changes\ndescribed in this advisory, refer to:\n\nhttps://access.redhat.com/articles/11258\n\nThe rh-nginx18-nginx service must be restarted for this update to take\neffect. \n\n5.

Vulnerability from variot
Integer underflow in the add_pseudoheader function in dnsmasq before 2.78 , when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service via a crafted DNS request. Dnsmasq versions 2.77 and earlier contains multiple vulnerabilities. dnsmasq Contains an integer underflow vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Multiple Siemens SCALANCE Products are prone to the following security vulnerabilities: 1. A buffer-overflow vulnerability 2. Multiple denial-of-service vulnerabilities Attackers can exploit these issues to execute arbitrary code within the context of affected device or cause a denial-of-service condition. This BID is being retired as a duplicate of BID 101085 Dnsmasq VU#973527 Multiple Security Vulnerabilities. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
===================================================================== Red Hat Security Advisory
Synopsis: Critical: dnsmasq security update Advisory ID: RHSA-2017:2836-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2836 Issue date: 2017-10-02 CVE Names: CVE-2017-14491 CVE-2017-14492 CVE-2017-14493 CVE-2017-14494 CVE-2017-14495 CVE-2017-14496 =====================================================================
- Summary:
An update for dnsmasq is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
- Relevant releases/architectures:
Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64
- Description:
The dnsmasq packages contain Dnsmasq, a lightweight DNS (Domain Name Server) forwarder and DHCP (Dynamic Host Configuration Protocol) server.
Security Fix(es):
-
A heap buffer overflow was found in dnsmasq in the code responsible for building DNS replies. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. (CVE-2017-14491)
-
A heap buffer overflow was discovered in dnsmasq in the IPv6 router advertisement (RA) handling code. This issue only affected configurations using one of these options: enable-ra, ra-only, slaac, ra-names, ra-advrouter, or ra-stateless. (CVE-2017-14492)
-
A stack buffer overflow was found in dnsmasq in the DHCPv6 code. (CVE-2017-14493)
-
An information leak was found in dnsmasq in the DHCPv6 relay code. An attacker on the local network could send crafted DHCPv6 packets to dnsmasq causing it to forward the contents of process memory, potentially leaking sensitive data. (CVE-2017-14494)
-
A memory exhaustion flaw was found in dnsmasq in the EDNS0 code. An attacker could send crafted DNS packets which would trigger memory allocations which would never be freed, leading to unbounded memory consumption and eventually a crash. This issue only affected configurations using one of the options: add-mac, add-cpe-id, or add-subnet. (CVE-2017-14495)
-
An integer underflow flaw leading to a buffer over-read was found in dnsmasq in the EDNS0 code. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash. This issue only affected configurations using one of the options: add-mac, add-cpe-id, or add-subnet. (CVE-2017-14496)
Red Hat would like to thank Felix Wilhelm (Google Security Team), Fermin J. Serna (Google Security Team), Gabriel Campana (Google Security Team), Kevin Hamacher (Google Security Team), and Ron Bowes (Google Security Team) for reporting these issues.

Multiple Siemens SCALANCE Products are prone to the following security vulnerabilities:\n1. A buffer-overflow vulnerability\n2. Multiple denial-of-service vulnerabilities\nAttackers can exploit these issues to execute arbitrary code within the context of affected device or cause a denial-of-service condition. \nThis BID is being retired as a duplicate of BID 101085 Dnsmasq VU#973527 Multiple Security Vulnerabilities. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Critical: dnsmasq security update\nAdvisory ID: RHSA-2017:2836-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://access.redhat.com/errata/RHSA-2017:2836\nIssue date: 2017-10-02\nCVE Names: CVE-2017-14491 CVE-2017-14492 CVE-2017-14493 \n CVE-2017-14494 CVE-2017-14495 CVE-2017-14496 \n=====================================================================\n\n1. Summary:\n\nAn update for dnsmasq is now available for Red Hat Enterprise Linux 7. \n\nRed Hat Product Security has rated this update as having a security impact\nof Critical. A Common Vulnerability Scoring System (CVSS) base score, which\ngives a detailed severity rating, is available for each vulnerability from\nthe CVE link(s) in the References section. \n\n2. Relevant releases/architectures:\n\nRed Hat Enterprise Linux Client (v. 7) - x86_64\nRed Hat Enterprise Linux Client Optional (v. 7) - x86_64\nRed Hat Enterprise Linux ComputeNode (v. 7) - x86_64\nRed Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64\nRed Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64\nRed Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64\nRed Hat Enterprise Linux Workstation (v. 7) - x86_64\nRed Hat Enterprise Linux Workstation Optional (v. 7) - x86_64\n\n3. Description:\n\nThe dnsmasq packages contain Dnsmasq, a lightweight DNS (Domain Name\nServer) forwarder and DHCP (Dynamic Host Configuration Protocol) server. \n\nSecurity Fix(es):\n\n* A heap buffer overflow was found in dnsmasq in the code responsible for\nbuilding DNS replies. An attacker could send crafted DNS packets to dnsmasq\nwhich would cause it to crash or, potentially, execute arbitrary code. \n(CVE-2017-14491)\n\n* A heap buffer overflow was discovered in dnsmasq in the IPv6 router\nadvertisement (RA) handling code. This issue only affected\nconfigurations using one of these options: enable-ra, ra-only, slaac,\nra-names, ra-advrouter, or ra-stateless. (CVE-2017-14492)\n\n* A stack buffer overflow was found in dnsmasq in the DHCPv6 code. (CVE-2017-14493)\n\n* An information leak was found in dnsmasq in the DHCPv6 relay code. An\nattacker on the local network could send crafted DHCPv6 packets to dnsmasq\ncausing it to forward the contents of process memory, potentially leaking\nsensitive data. (CVE-2017-14494)\n\n* A memory exhaustion flaw was found in dnsmasq in the EDNS0 code. An\nattacker could send crafted DNS packets which would trigger memory\nallocations which would never be freed, leading to unbounded memory\nconsumption and eventually a crash. This issue only affected configurations\nusing one of the options: add-mac, add-cpe-id, or add-subnet. \n(CVE-2017-14495)\n\n* An integer underflow flaw leading to a buffer over-read was found in\ndnsmasq in the EDNS0 code. An attacker could send crafted DNS packets to\ndnsmasq which would cause it to crash. This issue only affected\nconfigurations using one of the options: add-mac, add-cpe-id, or\nadd-subnet. (CVE-2017-14496)\n\nRed Hat would like to thank Felix Wilhelm (Google Security Team), Fermin J. \nSerna (Google Security Team), Gabriel Campana (Google Security Team), Kevin\nHamacher (Google Security Team), and Ron Bowes (Google Security Team) for\nreporting these issues. \n\n4.

Vulnerability from variot
The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (invalid pointer dereference and worker process crash) via a crafted UDP DNS response. Supplementary information : CWE Vulnerability type by CWE-476: NULL Pointer Dereference (NULL Pointer dereference ) Has been identified. nginx is prone to multiple denial-of-service vulnerabilities. Attackers can exploit these issues to cause denial-of-service conditions. There are security vulnerabilities in the resolver of nginx versions prior to 1.8.1 and versions 1.9.x prior to 1.9.10. These only affect nginx if the "resolver" directive is used in a configuration file.
For the oldstable distribution (wheezy), these problems have been fixed in version 1.2.1-2.2+wheezy4.
For the stable distribution (jessie), these problems have been fixed in version 1.6.2-5+deb8u1.
For the testing distribution (stretch), these problems have been fixed in version 1.9.10-1.
For the unstable distribution (sid), these problems have been fixed in version 1.9.10-1.
We recommend that you upgrade your nginx packages. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

"data": "The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (invalid pointer dereference and worker process crash) via a crafted UDP DNS response. Supplementary information : CWE Vulnerability type by CWE-476: NULL Pointer Dereference (NULL Pointer dereference ) Has been identified. nginx is prone to multiple denial-of-service vulnerabilities. \nAttackers can exploit these issues to cause denial-of-service conditions. There are security vulnerabilities in the resolver of nginx versions prior to 1.8.1 and versions 1.9.x prior to 1.9.10. These only affect nginx if\nthe \"resolver\" directive is used in a configuration file. \n\nFor the oldstable distribution (wheezy), these problems have been fixed\nin version 1.2.1-2.2+wheezy4. \n\nFor the stable distribution (jessie), these problems have been fixed in\nversion 1.6.2-5+deb8u1. \n\nFor the testing distribution (stretch), these problems have been fixed\nin version 1.9.10-1. \n\nFor the unstable distribution (sid), these problems have been fixed in\nversion 1.9.10-1. \n\nWe recommend that you upgrade your nginx packages. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Moderate: rh-nginx18-nginx security update\nAdvisory ID: RHSA-2016:1425-01\nProduct: Red Hat Software Collections\nAdvisory URL: https://access.redhat.com/errata/RHSA-2016:1425\nIssue date: 2016-07-14\nCVE Names: CVE-2016-0742 CVE-2016-0746 CVE-2016-0747 \n CVE-2016-4450 \n=====================================================================\n\n1.

var-201605-0213
Vulnerability from variot
The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 2.9.3 do not properly keep track of the recursion depth, which allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a crafted XML document containing a large number of nested entity references. libxml2 is prone to a stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Attackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause a denial-of-service condition. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
===================================================================== Red Hat Security Advisory
Synopsis: Important: libxml2 security update Advisory ID: RHSA-2016:1292-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2016:1292 Issue date: 2016-06-23 CVE Names: CVE-2016-1762 CVE-2016-1833 CVE-2016-1834 CVE-2016-1835 CVE-2016-1836 CVE-2016-1837 CVE-2016-1838 CVE-2016-1839 CVE-2016-1840 CVE-2016-3627 CVE-2016-3705 CVE-2016-4447 CVE-2016-4448 CVE-2016-4449 =====================================================================
- Summary:
An update for libxml2 is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
- Relevant releases/architectures:
Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64
- Description:
The libxml2 library is a development toolbox providing the implementation of various XML standards.
Security Fix(es):
A heap-based buffer overflow flaw was found in the way libxml2 parsed certain crafted XML input. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or execute arbitrary code with the permissions of the user running the application. (CVE-2016-1834, CVE-2016-1840)
Multiple denial of service flaws were found in libxml2. A remote attacker could provide a specially crafted XML file that, when processed by an application using libxml2, could cause that application to crash. (CVE-2016-1762, CVE-2016-1833, CVE-2016-1835, CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, CVE-2016-1839, CVE-2016-3627, CVE-2016-3705, CVE-2016-4447, CVE-2016-4448, CVE-2016-4449)
- Solution:
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258

"data": "The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 2.9.3 do not properly keep track of the recursion depth, which allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a crafted XML document containing a large number of nested entity references. libxml2 is prone to a stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. \nAttackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause a denial-of-service condition. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: libxml2 security update\nAdvisory ID: RHSA-2016:1292-01\nProduct: Red Hat Enterprise Linux\nAdvisory URL: https://access.redhat.com/errata/RHSA-2016:1292\nIssue date: 2016-06-23\nCVE Names: CVE-2016-1762 CVE-2016-1833 CVE-2016-1834 \n CVE-2016-1835 CVE-2016-1836 CVE-2016-1837 \n CVE-2016-1838 CVE-2016-1839 CVE-2016-1840 \n CVE-2016-3627 CVE-2016-3705 CVE-2016-4447 \n CVE-2016-4448 CVE-2016-4449 \n=====================================================================\n\n1.

Description:\n\nThe libxml2 library is a development toolbox providing the implementation\nof various XML standards. \n\nSecurity Fix(es):\n\nA heap-based buffer overflow flaw was found in the way libxml2 parsed\ncertain crafted XML input. A remote attacker could provide a specially\ncrafted XML file that, when opened in an application linked against\nlibxml2, would cause the application to crash or execute arbitrary code\nwith the permissions of the user running the application. (CVE-2016-1834,\nCVE-2016-1840)\n\nMultiple denial of service flaws were found in libxml2. A remote attacker\ncould provide a specially crafted XML file that, when processed by an\napplication using libxml2, could cause that application to crash. \n(CVE-2016-1762, CVE-2016-1833, CVE-2016-1835, CVE-2016-1836, CVE-2016-1837,\nCVE-2016-1838, CVE-2016-1839, CVE-2016-3627, CVE-2016-3705, CVE-2016-4447,\nCVE-2016-4448, CVE-2016-4449)\n\n4.

Severity ?
Summary
The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet.

Vulnerability from fkie_nvd
Published

Modified
2024-11-21 03:11
Severity ?
Summary
In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash.
