Ubuntu Security Notice USN-3151-3
December 05, 2016

linux-snapdragon vulnerability
==========================================================================

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

- Ubuntu 16.04 LTS

Summary:

The system could be made to crash or run programs as an administrator.

Software Description:
- linux-snapdragon: Linux kernel for Snapdragon Processors

Details:

Philip Pettersson discovered a race condition in the af_packet
implementation in the Linux kernel. A local unprivileged attacker could use
this to cause a denial of service (system crash) or run arbitrary code with
administrative privileges.

Update instructions:

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

Ubuntu 16.04 LTS:
linux-image-4.4.0-1039-snapdragon 4.4.0-1039.43
linux-image-snapdragon 4.4.0.1039.31

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.
