An exploitable integer overflow vulnerability exists within the MPEG-4
decoding functionality of the GPAC Project on Advanced Content library
v1.0.1. A specially crafted MPEG-4 input when reading an atom using the
‘sbgp’ FOURCC code can cause an integer overflow due to unchecked
arithmetic resulting in a heap-based buffer overflow that causes memory
corruption. An attacker can convince a user to open a video to trigger this
vulnerability.
