Attackers can supply a crafted FLIC file whose RLE and delta chunks write pixel data past frame storage, corrupting heap memory to crash applications or possibly execute code.","published":"2026-11-09T19:17:02.490","modified":"2026-11-09T19:17:02.490","cvss":{"score":7,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/FFmpeg/FFmpeg/commit/27f612b306eb04f81138173f705df9a9b055b01d","label":"FFmpeg/FFmpeg@27f612b"},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25702"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/flicvideo.c#L63"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg/commit/27f612b306eb04f81138173f705df9a9b055b01d"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-heap-buffer-overflow-via-flic-decoder-check-pixel-ptr"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-09T19:17:02.490"}}
