Description

The Asterisk project reports:

AST-2018-002 - By crafting an SDP message with an

invalid media format description Asterisk crashes when

using the pjsip channel driver because pjproject's sdp

parsing algorithm fails to catch the invalid media format

description.

AST-2018-003 - By crafting an SDP message body with

an invalid fmtp attribute Asterisk crashes when using the

pjsip channel driver because pjproject's fmtp retrieval

function fails to check if fmtp value is empty (set empty

if previously parsed as invalid).
