FreeBSD : asterisk -- RTP/RTCP information leak (c2ea3b31-9d75-11e7-bb13-001999f8d30b)

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

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
