NVD Description

Note: Versions mentioned in the description apply only to the upstream gpac package and not the gpac package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

Multiple exploitable integer overflow vulnerabilities exist within the MPEG-4 decoding functionality of the GPAC Project on Advanced Content library v1.0.1. A specially crafted MPEG-4 input can cause an integer overflow due to unchecked addition 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.
