Ubuntu Security Notice 2867-1 - It was discovered that libvirt incorrectly handled the firewall rules on bridge networks when the daemon was restarted. This could result in an unintended firewall configuration. This issue only applied to Ubuntu 12.04 LTS. Peter Krempa discovered that libvirt incorrectly handled locking when certain ACL checks failed. A local attacker could use this issue to cause libvirt to stop responding, resulting in a denial of service. This issue only applied to Ubuntu 14.04 LTS. Various other issues were also addressed.
