From ${URL} : OpenStack Security Advisory: 2013-008 CVE: CVE-2013-1838 Date: March 14, 2013 Title: Nova DoS by allocating all Fixed IPs Reporter: Vish Ishaya (Nebula) Products: Nova Affects: All versions Description: Vish Ishaya reported a vulnerability in Nova where there is no quota for Fixed IPs. Previously the instance quota acted as a proxy for a Fixed IP quota, but if your configuration allows an instance to consume more than one Fixed IP via an extension such as multinic then this is no longer true. Running out of Fixed IPs would result in not being able to spawn new instances.
