Vulnerability from variot
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings. The Linux kernel is prone to a memory-corruption vulnerability. Local attackers can exploit this issue to execute arbitrary code in contexts of the application or corrupt the kernel memory. Failed exploit attempts can result in a denial-of-service condition. Linux kernel 3.0 through versions 3.14.3 are vulnerable. This BID is being retired as a duplicate of BID 67199. The NFSv4 implementation is one of the distributed file system protocols. The vulnerability is caused by the program not properly managing the access rights of the tty driver.
CVE-2014-2851
Incorrect reference counting in the ping_init_sock() function allows
denial of service or privilege escalation.
For the stable distribution (wheezy), these problems have been fixed in version 3.2.57-3+deb7u1. This update also fixes a regression in the isci driver and suspend problems with certain AMD CPUs (introduced in the updated kernel from the Wheezy 7.5 point release).
For the unstable distribution (sid), these problems will be fixed soon. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

- Relevant releases/architectures:
MRG Realtime for RHEL 6 Server v.2 - noarch, x86_64
-
A race condition leading to a use-after-free flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled the addition of fragments to the LRU (Last-Recently Used) list under certain conditions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system by sending a large amount of specially crafted fragmented packets to that system. (CVE-2014-0100, Important)
-
A race condition flaw, leading to heap-based buffer overflows, was found in the way the Linux kernel's N_TTY line discipline (LDISC) implementation handled concurrent processing of echo output and TTY write operations originating from user space when the underlying TTY driver was PTY. An unprivileged, local user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-0196, Important)
-
A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. (CVE-2014-1737, Important)
-
It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use this flaw to obtain information about the kernel heap arrangement. (CVE-2014-1738, Low)
Note: A local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system.
-
A use-after-free flaw was found in the way the ping_init_sock() function of the Linux kernel handled the group_info reference counter. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2851, Important)
-
It was found that a remote attacker could use a race condition flaw in the ath_tx_aggr_sleep() function to crash the system by creating large network traffic on the system's Atheros 9k wireless network adapter. (CVE-2014-2672, Moderate)
-
A NULL pointer dereference flaw was found in the rds_iw_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. (CVE-2014-2678, Moderate)
-
A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. (CVE-2014-2706, Moderate)
-
It was found that the try_to_unmap_cluster() function in the Linux kernel's Memory Managment subsystem did not properly handle page locking in certain cases, which could potentially trigger the BUG_ON() macro in the mlock_vma_page() function. A local, unprivileged user could use this flaw to crash the system. (CVE-2014-3122, Moderate)
Red Hat would like to thank Matthew Daley for reporting CVE-2014-1737 and CVE-2014-1738. The CVE-2014-0100 issue was discovered by Nikolay Aleksandrov of Red Hat.
Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.34 and correct these issues. The system must be rebooted for this update to take effect.
- Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258
To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.

This update also fixes the following bug:
- Prior to this update, a guest-provided value was used as the head length of the socket buffer allocated on the host. If the host was under heavy memory load and the guest-provided value was too large, the allocation could have failed, resulting in stalls and packet drops in the guest's Tx path. With this update, the guest-provided value has been limited to a reasonable size so that socket buffer allocations on the host succeed regardless of the memory load on the host, and guests can send packets without experiencing packet drops or stalls.

Red Hat Enterprise Linux Workstation Optional (v. ============================================================================ Ubuntu Security Notice USN-2260-1 June 27, 2014
linux-lts-trusty vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in the kernel.
Software Description: - linux-lts-trusty: Block storage devices (udeb)
Details:
A flaw was discovered in the Linux kernel's pseudo tty (pty) device. (CVE-2014-0196)
Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. (CVE-2014-1737)
A flaw was discovered in the handling of network packets when mergeable buffers are disabled for virtual machines in the Linux kernel. Guest OS users may exploit this flaw to cause a denial of service (host OS crash) or possibly gain privilege on the host OS. (CVE-2014-2568)
A flaw was discovered in the Linux kernel's ping sockets. (CVE-2014-2851)
Sasha Levin reported a bug in the Linux kernel's virtual memory management subsystem. (CVE-2014-3122)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.13.0-30-generic 3.13.0-30.54~precise2 linux-image-3.13.0-30-generic-lpae 3.13.0-30.54~precise2
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-server, linux-powerpc), a standard system upgrade will automatically perform this as well

\u0026 !OPOST\" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings. The Linux kernel is prone to a memory-corruption vulnerability. \nLocal attackers can exploit this issue to execute arbitrary code in contexts of the application or corrupt the kernel memory. Failed exploit attempts can result in a denial-of-service condition. \nLinux kernel 3.0 through versions 3.14.3 are vulnerable. \nThis BID is being retired as a duplicate of BID 67199. The NFSv4 implementation is one of the distributed file system protocols. The vulnerability is caused by the program not properly managing the access rights of the tty driver. \n\nCVE-2014-2851\n\n Incorrect reference counting in the ping_init_sock() function allows\n denial of service or privilege escalation. \n\nFor the stable distribution (wheezy), these problems have been fixed in\nversion 3.2.57-3+deb7u1. This update also fixes a regression in the isci\ndriver and suspend problems with certain AMD CPUs (introduced in the\nupdated kernel from the Wheezy 7.5 point release). \n\nFor the unstable distribution (sid), these problems will be fixed soon. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n=====================================================================\n Red Hat Security Advisory\n\nSynopsis: Important: kernel-rt security update\nAdvisory ID: RHSA-2014:0557-01\nProduct: Red Hat Enterprise MRG for RHEL-6\nAdvisory URL: https://rhn.redhat.com/errata/RHSA-2014-0557.html\nIssue date: 2014-05-27\nCVE Names: CVE-2014-0100 CVE-2014-0196 CVE-2014-1737 \n CVE-2014-1738 CVE-2014-2672 CVE-2014-2678 \n CVE-2014-2706 CVE-2014-2851 CVE-2014-3122 \n=====================================================================\n\n1. Summary:\n\nUpdated kernel-rt packages that fix multiple security issues are now\navailable for Red Hat Enterprise MRG 2.5. \n\nThe Red Hat Security Response Team has rated this update as having\nImportant security impact. Common Vulnerability Scoring System (CVSS) base\nscores, which give detailed severity ratings, are available for each\nvulnerability from the CVE links in the References section. \n\n2. Relevant releases/architectures:\n\nMRG Realtime for RHEL 6 Server v.2 - noarch, x86_64\n\n3. \n\n* A race condition leading to a use-after-free flaw was found in the way\nthe Linux kernel\u0027s TCP/IP protocol suite implementation handled the\naddition of fragments to the LRU (Last-Recently Used) list under certain\nconditions. A remote attacker could use this flaw to crash the system or,\npotentially, escalate their privileges on the system by sending a large\namount of specially crafted fragmented packets to that system. \n(CVE-2014-0100, Important)\n\n* A race condition flaw, leading to heap-based buffer overflows, was found\nin the way the Linux kernel\u0027s N_TTY line discipline (LDISC) implementation\nhandled concurrent processing of echo output and TTY write operations\noriginating from user space when the underlying TTY driver was PTY. \nAn unprivileged, local user could use this flaw to crash the system or,\npotentially, escalate their privileges on the system. (CVE-2014-0196,\nImportant)\n\n* A flaw was found in the way the Linux kernel\u0027s floppy driver handled user\nspace provided data in certain error code paths while processing FDRAWCMD\nIOCTL commands. \n(CVE-2014-1737, Important)\n\n* It was found that the Linux kernel\u0027s floppy driver leaked internal kernel\nmemory addresses to user space during the processing of the FDRAWCMD IOCTL\ncommand. A local user with write access to /dev/fdX could use this flaw to\nobtain information about the kernel heap arrangement. (CVE-2014-1738, Low)\n\nNote: A local user with write access to /dev/fdX could use these two flaws\n(CVE-2014-1737 in combination with CVE-2014-1738) to escalate their\nprivileges on the system. \n\n* A use-after-free flaw was found in the way the ping_init_sock() function\nof the Linux kernel handled the group_info reference counter. A local,\nunprivileged user could use this flaw to crash the system or, potentially,\nescalate their privileges on the system. (CVE-2014-2851, Important)\n\n* It was found that a remote attacker could use a race condition flaw in\nthe ath_tx_aggr_sleep() function to crash the system by creating large\nnetwork traffic on the system\u0027s Atheros 9k wireless network adapter. \n(CVE-2014-2672, Moderate)\n\n* A NULL pointer dereference flaw was found in the rds_iw_laddr_check()\nfunction in the Linux kernel\u0027s implementation of Reliable Datagram Sockets\n(RDS). A local, unprivileged user could use this flaw to crash the system. \n(CVE-2014-2678, Moderate)\n\n* A race condition flaw was found in the way the Linux kernel\u0027s mac80211\nsubsystem implementation handled synchronization between TX and STA wake-up\ncode paths. A remote attacker could use this flaw to crash the system. \n(CVE-2014-2706, Moderate)\n\n* It was found that the try_to_unmap_cluster() function in the Linux\nkernel\u0027s Memory Managment subsystem did not properly handle page locking in\ncertain cases, which could potentially trigger the BUG_ON() macro in the\nmlock_vma_page() function. A local, unprivileged user could use this flaw\nto crash the system. (CVE-2014-3122, Moderate)\n\nRed Hat would like to thank Matthew Daley for reporting CVE-2014-1737 and\nCVE-2014-1738. The CVE-2014-0100 issue was discovered by Nikolay\nAleksandrov of Red Hat. \n\nUsers are advised to upgrade to these updated packages, which upgrade the\nkernel-rt kernel to version kernel-rt-3.10.33-rt32.34 and correct these\nissues. The system must be rebooted for this update to take effect. \n\n4. Solution:\n\nBefore applying this update, make sure all previously released errata\nrelevant to your system have been applied. \n\nThis update is available via the Red Hat Network. Details on how to use the\nRed Hat Network to apply this update are available at\nhttps://access.redhat.com/site/articles/11258\n\nTo install kernel packages manually, use \"rpm -ivh [package]\". Do not use\n\"rpm -Uvh\" as that will remove the running kernel binaries from your\nsystem. You may use \"rpm -e\" to remove old kernels after determining that\nthe new kernel functions properly on your system. \n\n5.

If the host was under heavy\nmemory load and the guest-provided value was too large, the allocation\ncould have failed, resulting in stalls and packet drops in the guest\u0027s Tx\npath. With this update, the guest-provided value has been limited to a\nreasonable size so that socket buffer allocations on the host succeed\nregardless of the memory load on the host, and guests can send packets\nwithout experiencing packet drops or stalls.
