libvirt vulnerability
==========================================================================

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

- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in libvirt.

Software Description:
- libvirt: Libvirt virtualization toolkit

Details:

USN-4047-1 fixed a vulnerability in libvirt. This update provides
the corresponding update for Ubuntu 14.04 ESM.

Original advisory details:

Matthias Gerstner and Ján Tomko discovered that libvirt incorrectly handled
certain API calls. An attacker could possibly use this issue to check for
arbitrary files, or execute arbitrary binaries. In the default
installation, attackers would be isolated by the libvirt AppArmor profile.

Update instructions:

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

Ubuntu 14.04 ESM:
libvirt-bin 1.2.2-0ubuntu13.1.28+esm1
libvirt0 1.2.2-0ubuntu13.1.28+esm1

After a standard system update you need to reboot your computer to make
all the necessary changes.
