It was discovered that a NULL pointer dereference existed in the keyring

subsystem of the Linux kernel. A local attacker could use this to cause a

denial of service (system crash). (CVE-2017-2647)

It was discovered that a race condition existed in the raw MIDI driver for

Update Instructions

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

Ubuntu 12.04 ESM:
  linux-image-3.13.0-164-generic  3.13.0-164.214~precise1
  linux-image-3.13.0-164-generic-lpae  3.13.0-164.214~precise1
  linux-image-generic-lpae-lts-trusty  3.13.0.164.154
  linux-image-generic-lts-trusty  3.13.0.164.154

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.
