Christey" <coley@...us.mitre.org> CC: oss-security@...ts.openwall.com, Joshua Colp <jcolp@...ium.com> Subject: CVE Request -- Asterisk AST-2012-001 / Remote DoS while processing crypto line for media stream with non-existing RTP 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 module has been loaded and video support has not been enabled. A remote attacker could provide a specially-crafted media stream negotiation request, which once processed by Asterisk would lead to asterisk daemon crash by processing crypto line for such media stream.
