Attackers can supply short audio streams under eight frames for RoQ DPCM transcoding, causing DPCM-quantized uninitialized heap data from frame_buffer to leak into output packets.","cvssScore":3.3,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","cwes":["CWE-908"],"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/roqaudioenc.c#L156","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/f71410e0288f0c40ae2fb5e5a4d7428763d08a71","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-roq-dpcm-encoder-uninitialized-heap-memory-disclosure","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/roqaudioenc.c#L156","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/f71410e0288f0c40ae2fb5e5a4d7428763d08a71","tags":[]}],"hasPoc":true,"ai":null}
