Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Wenlong Huang discovered that libvirt incorrectly handled certain RPC
calls. A remote attacker could exploit this and cause libvirt to
crash, resulting in a denial of service. This issue only affected
Ubuntu 12.04 LTS. (CVE-2012-4423)

Tingting Zheng discovered that libvirt incorrectly handled cleanup
under certain error conditions. A remote attacker could exploit this
and cause libvirt to crash, resulting in a denial of service, or
possibly execute arbitrary code. (CVE-2013-0170).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Update the affected libvirt-bin and / or libvirt0 packages.
