Denial Of Service (DoS)

gpac:bullseye is vulnerable to denial of service. Multiple exploitable integer overflow vulnerabilities exist within the MPEG-4 decoding functionality of the GPAC Project on Advanced Content library. A specially crafted MPEG-4 input in “stsz” decoder 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.
