c2ea3b31-9d75-11e7-bb13-001999f8d30b	asterisk -- RTP/RTCP information leak The Asterisk project reports: This is a follow up advisory to AST-2017-005. Insufficient RTCP packet validation could allow reading stale buffer contents and when combined with the "nat" and "symmetric_rtp" options allow redirecting where Asterisk sends the next RTCP report. The RTP stream qualification to learn the source address of media always accepted the first RTP packet as the new source and allowed what AST-2017-005 was mitigating. The intent was to qualify a series of packets before accepting the new source address. The RTP/RTCP stack will now validate RTCP packets before processing them.
