Details:
William Liu and Jamie Hill-Daniel discovered that the file system context
functionality in the Linux kernel contained an integer underflow
vulnerability, leading to an out-of-bounds write. A local attacker could
use this to cause a denial of service (system crash) or execute arbitrary
code.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:

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.
