USN-2233-1: Linux kernel vulnerabilities

5 June 2014

linux vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 10.04 LTS

Summary

Several security issues were fixed in the kernel.

Software Description

  • linux - Linux kernel

Details

Pinkie Pie discovered a flaw in the Linux kernel’s futex subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrative privileges. (CVE-2014-3153)

Dmitry Vyukov reported a flaw in the Linux kernel’s handling of IPv6 UDP Fragmentation Offload (UFO) processing. A remote attacker could leverage this flaw to cause a denial of service (system crash). (CVE-2013-4387)

Hannes Frederic Sowa discovered a flaw in the Linux kernel’s UDP Fragmentation Offload (UFO). An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2013-4470)

A flaw was discovered in the Linux kernel’s IPC reference counting. An unprivileged local user could exploit this flaw to cause a denial of service (OOM system crash). (CVE-2013-4483)

halfdog reported an error in the AMD K7 and K8 platform support in the Linux kernel. An unprivileged local user could exploit this flaw on AMD based systems to cause a denial of service (task kill) or possibly gain privileges via a crafted application. (CVE-2014-1438)

Sasha Levin reported a bug in the Linux kernel’s virtual memory management subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash). (CVE-2014-3122)

linux-image-2.6.32-61-virtual - 2.6.32-61.124

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. 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.
