Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Details

A heap out-of-bounds memory write exists in FFMPEG since version 5.1. The size calculation in build_open_gop_key_points() goes through all entries in the loop and adds sc->ctts_data[i].count to sc->sample_offsets_count. This can lead to an integer overflow resulting in a small allocation with `av_calloc(). An attacker can cause remote code execution via a malicious mp4 file. We recommend upgrading past commit c953baa084607dd1d84c3bfcce3cf6a87c3e6e05
