{"id":"UBUNTU-CVE-2017-14055","details":"In libavformat/mvdec.c in FFmpeg 3.3.3, a DoS in mv_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. When a crafted MV file, which claims a large \"nb_frames\" field in the header but does not contain sufficient backing data, is provided, the loop over the frames would consume huge CPU and memory resources, since there is no EOF check inside the loop.","modified":"2025-09-08T16:44:25Z","published":"2017-08-31T15:29:00Z","upstream":["CVE-2017-14055"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-14055"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-14055"}],"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_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","binary_version":"7:2.8.14-0ubuntu0.16.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-14055.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:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
