USN-2928-1: Linux kernel vulnerability

Releases

• Ubuntu 12.04

Packages

• linux - Linux kernel

Details

Andrey Konovalov discovered that the ALSA USB MIDI driver incorrectly
performed a double-free. A local attacker with physical access could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code with administrative privileges.

Update instructions

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

Ubuntu 12.04

• linux-image-3.2.0-101-omap - 3.2.0-101.141
• linux-image-3.2.0-101-powerpc64-smp - 3.2.0-101.141
• linux-image-3.2.0-101-highbank - 3.2.0-101.141
• linux-image-3.2.0-101-powerpc-smp - 3.2.0-101.141
• linux-image-3.2.0-101-generic - 3.2.0-101.141
• linux-image-3.2.0-101-virtual - 3.2.0-101.141
• linux-image-3.2.0-101-generic-pae - 3.2.0-101.141

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.
