Title
PJSIP vulnerable to heap buffer overflow when decoding STUN message
Summary
PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. Buffer overread is possible when parsing a specially crafted STUN message with unknown attribute. The vulnerability affects applications that uses STUN including PJNATH and PJSUA-LIB. The patch is available as a commit in the master branch (2.13.1).
