Because of a missing authorization check on port binding, by guessing an instance_id a tenant may retrieve another tenant's metadata resulting in information disclosure. Only OpenStack setups running neutron-metadata-agent are affected. Icehouse (development branch) fix: https://review.openstack.org/61439 (neutron) https://review.openstack.org/61428 (nova) Havana fix: https://review.openstack.org/61442 (neutron) https://review.openstack.org/61435 (nova) Grizzly fix: https://review.openstack.org/61443 (neutron) https://review.openstack.org/61437 (nova) Notes: This fix will be included in the icehouse-2 development milestone and in a future 2013.2.1 release.

By generating EC2 credentials using a trust-scoped token, a trustee may retrieve a token not scoped to the trust, therefore elevating privileges to all of the trustor's roles. Only Keystone setups enabling EC2-style authentication are affected. Icehouse (development branch) fix: https://review.openstack.org/61419 Havana fix: https://review.openstack.org/61425 Notes: This fix will be included in the icehouse-2 development milestone and in a future 2013.2.1 release.
