Attackers can supply a crafted JPEG XS stream, for example in MPEG-TS, with oversized headers to repeatedly leak decoder threads and buffers, exhausting memory.","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-401"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25416","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/libsvtjpegxsdec.c#L132","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/3aa561b0dd2054182fbb9548b4526e8500d52a52","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-resource-leak-in-libsvtjpegxs-jpeg-xs-decoder-wrapper","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/libsvtjpegxsdec.c#L132","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/3aa561b0dd2054182fbb9548b4526e8500d52a52","tags":[]}],"hasPoc":true,"ai":null}
