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.
Upstream patch against the v1.8.x branch:
Upstream patch against the v1.10.x branch:
Could you allocate a CVE identifier for this?
Thank you && Regards, Jan.
