USN-1313-1: Linux Kernel (Oneiric backport) vulnerability
Ubuntu Security Notice USN-1313-1
19th December, 2011
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Several security issues were fixed in the kernel.
- linux-lts-backport-oneiric - Linux kernel backport from Oneiric
Nick Bowler discovered the kernel GHASH message digest algorithm
incorrectly handled error conditions. A local attacker could exploit this
to cause a kernel oops.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 10.04 LTS:
- linux-image-3.0.0-14-generic 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-generic-pae 3.0.0-14.23~lucid1
- linux-image-3.0.0-14-virtual 3.0.0-14.23~lucid1
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.
