Attackers can supply 24-bit 48 or 96 kHz audio whose length leaves a short final frame, causing the loop counter to wrap and crash the transcoding process.","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-125"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25694","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/pcm-dvdenc.c#L120","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/cfe6a6cd7de59341a70ebe6a2d477f3281aec834","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-out-of-bounds-read-via-pcm-dvd-encoder","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/pcm-dvdenc.c#L120","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/cfe6a6cd7de59341a70ebe6a2d477f3281aec834","tags":[]}],"hasPoc":true,"ai":null}
