| Doc Text: |
A flaw was found in PJSIP, a free and open-source multimedia communication library. An attacker could exploit a heap buffer underflow vulnerability by sending specially crafted, malformed H.264 bitstreams without NAL unit start codes. This unchecked pointer arithmetic can cause the packetizer to read from memory before the allocated buffer, leading to a denial of service.
