GHSA-M864-5788-G574

Vulnerability from github – Published: 2022-09-25 00:00 – Updated: 2022-09-27 00:00

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

Severity ?

7.8 (High)
