Finalized impact description being used in advisory (also covers bug 1202266):
----
Title: XenAPI security groups not kept through migrate or resize
Reporter: Chris Behrens (Rackspace) and Vangelis Tasoulas
Products: Nova
Affects: All supported versions prior to Havana
Description:
Chris Behrens with Rackspace and Vangelis Tasoulas reported a set of vulnerabilities in OpenStack Nova's XenAPI hypervisor backend. When migrating or resizing an instance, including live migration, existing security groups may not be reapplied after the operation completes. This can lead to unintentional network exposure for virtual machines. Only setups using the XenAPI backend are affected.
