Attackers can supply crafted H.264 streams with malformed NAL units that repeatedly abandon pictures, leaking the bitstream_buffers table continuously and 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-401"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25231","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vdpau.c#L378","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/2c6cd8098844f2367f8ba0a3a483e405c8f76449","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/eac2bedcf6245552b39eed32b334851bc6a1b8fa","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-memory-leak-via-vdpau-hwaccel-bitstream-buffer-table","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/vdpau.c#L378","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/2c6cd8098844f2367f8ba0a3a483e405c8f76449","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/eac2bedcf6245552b39eed32b334851bc6a1b8fa","tags":[]}],"hasPoc":true,"ai":null}
