libvirt vulnerabilities

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

- Ubuntu 12.10
- Ubuntu 12.04 LTS


libvirt could be made to crash or run programs if it received specially
crafted network traffic.

Software Description:
- libvirt: Libvirt virtualization toolkit


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)

Update instructions:

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

Ubuntu 12.10:
  libvirt-bin                     0.9.13-0ubuntu12.2
  libvirt0                        0.9.13-0ubuntu12.2

Ubuntu 12.04 LTS:
  libvirt-bin                     0.9.8-2ubuntu17.7
  libvirt0                        0.9.8-2ubuntu17.7

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

  CVE-2012-4423, CVE-2013-0170
