Attackers can supply crafted Dolby Vision HEVC or AV1 files that leak one RPU allocation per encoded frame during libx265 transcoding, causing unbounded memory growth and denial of service.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-401"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25416","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/libx265.c#L880","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/8dc4af2bbbd0d650e299a3d327bd48c775120e11","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-memory-leak-via-libx265-dolby-vision-rpu-payloads","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/libx265.c#L880","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/8dc4af2bbbd0d650e299a3d327bd48c775120e11","tags":[]}],"hasPoc":true,"ai":null}
