{"id":"UBUNTU-CVE-2017-14169","details":"In the mxf_read_primer_pack function in libavformat/mxfdec.c in FFmpeg 3.3.3 -\u003e 2.4, an integer signedness error might occur when a crafted file, which claims a large \"item_num\" field such as 0xffffffff, is provided. As a result, the variable \"item_num\" turns negative, bypassing the check for a large value.","modified":"2025-09-08T16:44:26Z","published":"2017-09-07T06:29:00Z","upstream":["CVE-2017-14169"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-14169"},{"type":"REPORT","url":"https://github.com/FFmpeg/FFmpeg/commit/9d00fb9d70ee8c0cc7002b89318c5be00f1bbdad"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-14169"}],"affected":[{"package":{"name":"ffmpeg","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/ffmpeg@7:2.8.14-0ubuntu0.16.04.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7:2.8.14-0ubuntu0.16.04.1"}]}],"versions":["7:2.7.2-1build1","7:2.8.1-1ubuntu1","7:2.8.2-1ubuntu1","7:2.8.3-1","7:2.8.4-1","7:2.8.4-1ubuntu1","7:2.8.4-1ubuntu2","7:2.8.4-1ubuntu3","7:2.8.4-1ubuntu4","7:2.8.6-1ubuntu1","7:2.8.6-1ubuntu2","7:2.8.8-0ubuntu0.16.04.1","7:2.8.10-0ubuntu0.16.04.1","7:2.8.11-0ubuntu0.16.04.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"ffmpeg"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libav-tools"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavcodec-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavcodec-extra"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavcodec-ffmpeg-extra56"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavcodec-ffmpeg56"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavdevice-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavdevice-ffmpeg56"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavfilter-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavfilter-ffmpeg5"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavformat-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavformat-ffmpeg56"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavresample-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavresample-ffmpeg2"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavutil-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libavutil-ffmpeg54"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libpostproc-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libpostproc-ffmpeg53"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libswresample-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libswresample-ffmpeg1"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libswscale-dev"},{"binary_version":"7:2.8.14-0ubuntu0.16.04.1","binary_name":"libswscale-ffmpeg3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-14169.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
