Description Laura Pardo 2018-02-22 18:06:54 UTC 
A flaw was discovered in Asterisk 13.x, 14.x, 15.x and 13.18. By crafting an SDP message with an invalid media format description Asterisk crashes with a segmentation fault when using the pjsip channel driver because pjproject's sdp parsing algorithm fails to catch the invalid media format description.
