In versions 2.16 and below, there is a critical Heap-based Buffer Overflow vulnerability in PJSIP&#8217;s H.264 unpacketizer. The bug occurs when processing malformed SRTP packets, where the unpacketizer reads a 2-byte NAL unit size field without validating that both bytes are within the payload buffer bounds. The vulnerability affects applications that receive video using H.264.
