GPAC has an unspecified vulnerability

A security vulnerability exists in GPAC Project Advanced Content, an open source multimedia framework, which stems from multiple exploitable integer overflow vulnerabilities in the MPEG-4 decoding functionality of Advanced Content. A specially crafted MPEG-4 file input could cause an integer overflow due to unchecked addition operations, which could be exploited by an attacker to cause a heap-based buffer overflow resulting in memory corruption.
