Attackers can supply a crafted H.264 packet with many slices of alternating picture order counts, forcing h264_queue_frame() to allocate tree nodes per slice and deny 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-770"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25569","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/bsf/dts2pts.c#L363","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/d8013c061725631261d7326c07d2af3a67fa4bc1","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-cpu-exhaustion-via-dts2pts-bitstream-filter","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/bsf/dts2pts.c#L363","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/d8013c061725631261d7326c07d2af3a67fa4bc1","tags":[]}],"hasPoc":true,"ai":null}
