Ubuntu Security Notice 1954-1 - It was discovered that libvirt used the pkcheck tool in an unsafe manner. A local attacker could possibly use this flaw to bypass polkit authentication. In Ubuntu, libvirt polkit authentication is not enabled by default. It was discovered that libvirt incorrectly handled certain memory stats requests. A remote attacker could use this issue to cause libvirt to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS, Ubuntu 12.10, and Ubuntu 13.04. Various other issues were also addressed.
