Attackers can supply a crafted VP9 stream with invalid tile sizes decoded with slice threading to leak packet buffers and units, exhausting memory in the decoding application.","cvssScore":4.7,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/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/25232","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vp9.c#L1766","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/bcce3232016695f5e482867519c45727a0a2a2c9","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-8.0-through-9.0.2-memory-leak-in-vp9-decoder-via-vp9-decode-frame","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vp9.c#L1766","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/bcce3232016695f5e482867519c45727a0a2a2c9","tags":[]}],"hasPoc":true,"ai":null}
