Attackers can supply a crafted VVC (H.266) stream that repeatedly replaces parameter sets, steadily growing memory use and causing denial of service.","cvssScore":3.3,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","cwes":["CWE-401"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25088","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vvc/refs.c#L133","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/a13e27336a61a3452e1ab8b4bb132c4174c67498","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-vvc-decoder-memory-leak-via-alloc-frame","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vvc/refs.c#L133","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/a13e27336a61a3452e1ab8b4bb132c4174c67498","tags":[]}],"hasPoc":true,"ai":null}
