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. This issue is similar to GHSA-9pfh-r8x4-w26w. Possible buffer overread when parsing a certain STUN message. The vulnerability affects applications that uses STUN including PJNATH and PJSUA-LIB. The patch is available as commit in the master branch.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product reads data past the end, or before the beginning, of the intended buffer.
