USN-7122-1: Linux kernel vulnerability

Releases

• Ubuntu 14.04 ESM

Packages

• linux - Linux kernel

Details

A security issue was discovered in the Linux kernel.
An attacker could possibly use this to compromise the system.
This update corrects flaws in the following subsystems:

• x86 architecture;

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04

• linux-image-3.13.0-200-generic - 3.13.0-200.251
  Available with Ubuntu Pro
• linux-image-3.13.0-200-lowlatency - 3.13.0-200.251
  Available with Ubuntu Pro
• linux-image-generic - 3.13.0.200.210
  Available with Ubuntu Pro
• linux-image-generic-lts-trusty - 3.13.0.200.210
  Available with Ubuntu Pro
• linux-image-lowlatency - 3.13.0.200.210
  Available with Ubuntu Pro
• linux-image-server - 3.13.0.200.210
  Available with Ubuntu Pro
• linux-image-virtual - 3.13.0.200.210
  Available with Ubuntu Pro

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.
