========================================================================== Ubuntu Security Notice USN-2366-1 September 30, 2014
A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in libvirt.
Software Description: - libvirt: Libvirt virtualization toolkit
Daniel P. Berrange and Richard Jones discovered that libvirt incorrectly handled XML documents containing XML external entity declarations. An attacker could use this issue to cause libvirtd to crash, resulting in a denial of service on all affected releases, or possibly read arbitrary files if fine grained access control was enabled on Ubuntu 14.04 LTS. (CVE-2014-0179, CVE-2014-5177)
Luyao Huang discovered that libvirt incorrectly handled certain blkiotune queries. An attacker could use this issue to cause libvirtd to crash, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-3633)
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: libvirt-bin 1.2.2-0ubuntu13.1.5 libvirt0 1.2.2-0ubuntu13.1.5
Ubuntu 12.04 LTS: libvirt-bin 0.9.8-2ubuntu17.20 libvirt0 0.9.8-2ubuntu17.20
Ubuntu 10.04 LTS: libvirt-bin 0.7.5-5ubuntu27.25 libvirt0 0.7.5-5ubuntu27.25
After a standard system update you need to reboot your computer to make all the necessary changes.
