VUL-0: CVE-2017-15672: ffmpeg: out-of-array read in slice counting
Last modified: 2021-09-11 02:37:31 UTC
CVE-2017-15672 Affected package: ffmpeg Affected versions: <= 3.3.4 FFmpeg could read out of bounds of buffer when it parsing an craft mp4 file. While ffmpeg calculating “bytestream_end” in ff_init_range_encoder() of libavcodec/rangecoder.c, it uses a small “buf_size”. But when using this structure in read_header() of libavcodec/ffv1dec.c, It will minus a bigger “trailer” than “buf_size” to read “size” through AV_RB24(). So it reads the front memory of “bytestream”, and get an error “size”. The issue was fixed with the following commit: http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=c20f4fcb74da2d0432c7b54499bb98f48236b904 Regards Reported by Zhibin Hu and Yihan Lian from Qihoo 360 GearTeam References: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-15672 http://seclists.org/oss-sec/2017/q4/189 http://people.canonical.com/~ubuntu-security/cve/2017/CVE-2017-15672.html http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-15672
