=========================================================================Ubuntu Security Notice USN-2928-1
March 14, 2016

linux vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

The system could be made to crash or run programs as an administrator by
someone with physical access.

Software Description:
- 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 LTS:
  linux-image-3.2.0-101-generic   3.2.0-101.141
  linux-image-3.2.0-101-generic-pae  3.2.0-101.141
  linux-image-3.2.0-101-highbank  3.2.0-101.141
  linux-image-3.2.0-101-omap      3.2.0-101.141
  linux-image-3.2.0-101-powerpc-smp  3.2.0-101.141
  linux-image-3.2.0-101-powerpc64-smp  3.2.0-101.141
  linux-image-3.2.0-101-virtual   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.
