The binary MP4Box in Gpac 1.0.1 has a double-free vulnerability in the avc_compute_poc function in av_parsers.c, which allows attackers to cause a denial of service, even code execution and escalation of privileges.

Weakness

The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
