Attackers can supply a crafted truncated Interplay C93 file so draw_n_color() writes uninitialized stack bytes into decoded frames, disclosing stack memory contents.","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/25715","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/c93.c#L198","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/ac0106851a4dac555c967421dfc96c0135183133","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-c93-decoder-uninitialized-stack-memory-disclosure","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/c93.c#L198","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/ac0106851a4dac555c967421dfc96c0135183133","tags":[]}],"hasPoc":true,"ai":null}
