CVE-2021-21834 (GCVE-0-2021-21834)

Vulnerability from cvelistv5 – Published: 2021-08-25 18:19 – Updated: 2024-08-03 18:23

Summary

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 for the “co64” FOURCC 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.

Severity

8.8 (High)
