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

- Ubuntu 14.04 LTS

Summary:

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

Software Description:
- linux: Linux kernel

Details:

Yevgeny Pats discovered that the session keyring implementation in the
Linux kernel did not properly reference count when joining an existing
session keyring. A local attacker 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 14.04 LTS:
linux-image-3.13.0-76-generic 3.13.0-76.120
linux-image-3.13.0-76-generic-lpae 3.13.0-76.120
linux-image-3.13.0-76-lowlatency 3.13.0-76.120
linux-image-3.13.0-76-powerpc-e500 3.13.0-76.120
linux-image-3.13.0-76-powerpc-e500mc 3.13.0-76.120
linux-image-3.13.0-76-powerpc-smp 3.13.0-76.120
linux-image-3.13.0-76-powerpc64-emb 3.13.0-76.120
linux-image-3.13.0-76-powerpc64-smp 3.13.0-76.120

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.
