CVE-2012-0885 was already assigned to AST-2012-001 based on a request from the upstream vendor. They probably updated their advisory since your initial request:

Hello Kurt, Steve, vendors, a denial of service flaw was found in the way asterisk processed certain requests to negotiate secure video stream, when the res_srtp Asterisk modulehas been loaded and video support has not been enabled. A remote attacker couldprovide a specially-crafted media stream negotiation request, which onceprocessed by Asterisk would lead to asterisk daemon crash by processing cryptoline for such media stream.
