Last modified
CVE-2021-21835 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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 decoding the atom associated with the “csgp” FOURCC can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. EPSS estimates a 1.43% chance of exploitation in the next 30 days.
