This can result in an integer underflow. Note, this requires ICE or WebRTC support to be in use with a malicious remote party. AST-2022-005 - When acting as a UAC, and when placing an outgoing call to a target that then forks Asterisk may experience undefined behavior (crashes, hangs, etc) after a dialog set is prematurely freed. AST-2022-006 - If an incoming SIP message contains a malformed multi-part body an out of bounds read access may occur, which can result in undefined behavior. Note, its currently uncertain if there is any externally exploitable vector within Asterisk for this issue, but providing this as a security issue out of caution.
