Attackers can supply crafted input whose resolution grows mid-stream, transcoded to OpenEXR with RLE compression, to write pointers past the scanline array and crash the application.","published":"2026-11-09T20:18:12.367","modified":"2026-11-09T20:18:12.367","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/9b99973b2bbecee0b7e1e57035b95498b42f54a6","label":"FFmpeg/FFmpeg@9b99973"},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25682"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/exrenc.c#L226"},{"type":"WEB","url":"https://github.com/FFmpeg/FFmpeg/commit/9b99973b2bbecee0b7e1e57035b95498b42f54a6"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-heap-buffer-overflow-in-exr-encoder-rle-path"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-09T20:18:12.367"}}
