Critical

Base vector

AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions FFMPEG versions 5.1 and later

Description A heap out-of-bounds memory write exists in the build open gop key points() function due to an integer overflow. This occurs when the size calculation adds sc->ctts data[i].count to sc->sample offsets count, potentially resulting in a small allocation with av calloc(). An attacker can cause remote code execution via a malicious mp4 file.

Recommendations For FFMPEG versions 5.1 and later, upgrade past commit c953baa084607dd1d84c3bfcce3cf6a87c3e6e05 to resolve the issue. As a temporary workaround, consider restricting access to malicious mp4 files to minimize the risk of exploitation.
