Ubuntu 10.04 LTS: USN-1313-1 Moderate: Linux Kernel Issue

Revise your Ubuntu 10.04 LTS installation to address vulnerabilities affecting the linux-lts-backport-oneiric kernel.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-lts-backport-oneiric: Linux kernel backport from Oneiric

Details:

Nick Bowler discovered the kernel GHASH message digest algorithm

incorrectly handled error conditions. A local attacker could exploit this

to cause a kernel oops.

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-3.0.0-14-generic    3.0.0-14.23~lucid1
  linux-image-3.0.0-14-generic-pae  3.0.0-14.23~lucid1
  linux-image-3.0.0-14-server     3.0.0-14.23~lucid1
  linux-image-3.0.0-14-virtual    3.0.0-14.23~lucid1

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.
