Out-of-bounds Write

CVE-2022-2566

High
7.8/10

Summary

A heap out-of-bounds memory write exists in FFMPEG. 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. This issue affects versions 5.1 and 5.2-dev
