Attackers can set TileWidth or TileLength near INT_MAX so the tile loop never runs, outputting a frame exposing uninitialized or stale heap memory.","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-190"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24999","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/tiff.c#L1007","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/a9c070e52fecb7fb247db829130899db07953823","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-integer-overflow-via-dng-decode-tiles-in-libavcodec-tiff-c","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/tiff.c#L1007","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/a9c070e52fecb7fb247db829130899db07953823","tags":[]}],"hasPoc":true,"ai":null}
