USN-3144-1: Linux kernel vulnerability

Releases

• Ubuntu 12.04

Packages

• linux - Linux kernel

Details

Marco Grassi discovered that the driver for Areca RAID Controllers in the
Linux kernel did not properly validate control messages. A local attacker
could use this to cause a denial of service (system crash) or possibly gain
privileges.

Update instructions

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

Ubuntu 12.04

• linux-image-powerpc-smp - 3.2.0.116.132
• linux-image-3.2.0-116-generic - 3.2.0-116.158
• linux-image-3.2.0-116-virtual - 3.2.0-116.158
• linux-image-3.2.0-116-generic-pae - 3.2.0-116.158
• linux-image-generic - 3.2.0.116.132
• linux-image-generic-pae - 3.2.0.116.132
• linux-image-highbank - 3.2.0.116.132
• linux-image-3.2.0-116-powerpc64-smp - 3.2.0-116.158
• linux-image-virtual - 3.2.0.116.132
• linux-image-powerpc64-smp - 3.2.0.116.132
• linux-image-3.2.0-116-highbank - 3.2.0-116.158
• linux-image-3.2.0-116-omap - 3.2.0-116.158
• linux-image-3.2.0-116-powerpc-smp - 3.2.0-116.158
• linux-image-omap - 3.2.0.116.132

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.
