OpenStack Security Advisory: 2013-030 CVE: CVE-2013-4497 Date: November 14, 2013 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.

The Havana release (2013.2) is not affected.

Grizzly fixes (will be included in a future stable point release): https://review.openstack.org/52987 https://review.openstack.org/52991
