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.","cvssScore":7,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25702","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/flicvideo.c#L63","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/27f612b306eb04f81138173f705df9a9b055b01d","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-heap-buffer-overflow-via-flic-decoder-check-pixel-ptr","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/flicvideo.c#L63","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/27f612b306eb04f81138173f705df9a9b055b01d","tags":[]}],"hasPoc":true,"ai":null}
