Attackers can supply a Westwood VQA file omitting or truncating the CBF0/CBFZ codebook chunk, causing vqa_decode_frame() to render frames from leftover heap bytes visible in decoded output.","cvssScore":3.3,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","cwes":["CWE-908"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24670","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vqavideo.c#L186","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/f9df3577ac40aaee06f82f05eab8249cbab3cd33","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-heap-memory-disclosure-via-vqa-video-decoder","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vqavideo.c#L186","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/f9df3577ac40aaee06f82f05eab8249cbab3cd33","tags":[]}],"hasPoc":true,"ai":null}
