CVE-2021-21850

Priority
Description
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 can cause an integer overflow when
the library encounters an atom using the “trun” FOURCC code 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.
