Attackers can supply a crafted HEVC or AV1 input with a nonzero frame rate numerator and zero denominator to the dovi_rpu bitstream filter or libx265, libaom, or libsvtav1 encoders, causing denial of service.","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-369"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25408","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/dovi_rpuenc.c#L187","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/ab28d57ba2ec07b41b4a60ed8806b13a39ec86fe","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-division-by-zero-via-dovi-configure-ext-in-dovi-rpuenc-c","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/dovi_rpuenc.c#L187","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/ab28d57ba2ec07b41b4a60ed8806b13a39ec86fe","tags":[]}],"hasPoc":true,"ai":null}
