Attackers can supply a crafted file with a packet over 256 MB, overflowing the bit count so init_get_bits() fails unchecked and get_bits() crashes during MP4, Matroska, FLV or LATM remuxing.","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-252"],"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/aac_adtstoasc.c#L82","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/3b1cbb5e0f66b85d15f1d3527436520b3f4711ec","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-null-pointer-dereference-via-aac-adtstoasc-bitstream-filter","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/bsf/aac_adtstoasc.c#L82","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/3b1cbb5e0f66b85d15f1d3527436520b3f4711ec","tags":[]}],"hasPoc":true,"ai":null}
