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

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.
