{"id":"ALPINE-CVE-2017-14171","details":"In libavformat/nsvdec.c in FFmpeg 2.4 and 3.3.3, a DoS in nsv_parse_NSVf_header() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted NSV file, which claims a large \"table_entries_used\" field in the header but does not contain sufficient backing data, is provided, the loop over 'table_entries_used' would consume huge CPU resources, since there is no EOF check inside the loop.","modified":"2025-11-19T06:08:52.525701Z","published":"2017-09-07T06:29:00.297Z","upstream":["CVE-2017-14171"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2017-14171"}],"affected":[{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.4","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.11-r0"}]}],"versions":["0.10-r0","0.10-r1","0.10-r2","0.10.2-r0","0.11-r0","0.11.1-r0","0.11.1-r1","0.11.2-r1","0.5-r0","0.6-r0","0.6-r1","0.6-r2","0.6.1-r0","0.6.1-r1","0.6.2-r0","0.6.2-r1","0.6.2-r2","0.6.3-r0","0.6.3-r1","0.6.3-r2","0.8-r0","0.8.1-r0","0.8.2-r0","0.8.3-r0","0.8.4-r0","0.8.5-r0","0.8.5-r1","0.8.6-r0","0.8.7-r0","0.9-r0","0.9.1-r0","1.0-r0","1.0-r1","1.0-r2","1.0.1-r0","1.0.1-r1","1.1-r1","1.1.2-r1","1.1.2-r2","1.1.2-r3","1.1.3-r0","1.1.4-r0","1.2-r0","1.2-r1","1.2.1-r0","1.2.2-r0","1.2.4-r0","2.0.2-r0","2.1-r0","2.1.1-r0","2.1.3-r0","2.1.4-r0","2.2-r0","2.2.2-r0","2.2.3-r0","2.2.4-r0","2.2.4-r1","2.2.4-r2","2.2.4-r3","2.3-r0","2.3.1-r0","2.3.2-r0","2.3.3-r0","2.3.4-r0","2.3.4-r1","2.3.4-r2","2.3.5-r0","2.5.1-r0","2.5.2-r0","2.5.2-r1","2.5.3-r0","2.5.4-r0","2.6.1-r0","2.6.2-r0","2.6.2-r1","2.6.2-r2","2.6.3-r0","2.7-r0","2.7.1-r0","2.7.1-r1","2.7.2-r0","2.8-r0","2.8-r1","2.8-r2","2.8.1-r0","2.8.2-r0","2.8.2-r1","2.8.3-r0","2.8.5-r0","3.0.1-r0","3.0.2-r0","3.0.2-r1","3.0.7-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14171.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.5","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.11-r0"}]}],"versions":["0.10-r0","0.10-r1","0.10-r2","0.10.2-r0","0.11-r0","0.11.1-r0","0.11.1-r1","0.11.2-r1","0.5-r0","0.6-r0","0.6-r1","0.6-r2","0.6.1-r0","0.6.1-r1","0.6.2-r0","0.6.2-r1","0.6.2-r2","0.6.3-r0","0.6.3-r1","0.6.3-r2","0.8-r0","0.8.1-r0","0.8.2-r0","0.8.3-r0","0.8.4-r0","0.8.5-r0","0.8.5-r1","0.8.6-r0","0.8.7-r0","0.9-r0","0.9.1-r0","1.0-r0","1.0-r1","1.0-r2","1.0.1-r0","1.0.1-r1","1.1-r1","1.1.2-r1","1.1.2-r2","1.1.2-r3","1.1.3-r0","1.1.4-r0","1.2-r0","1.2-r1","1.2.1-r0","1.2.2-r0","1.2.4-r0","2.0.2-r0","2.1-r0","2.1.1-r0","2.1.3-r0","2.1.4-r0","2.2-r0","2.2.2-r0","2.2.3-r0","2.2.4-r0","2.2.4-r1","2.2.4-r2","2.2.4-r3","2.3-r0","2.3.1-r0","2.3.2-r0","2.3.3-r0","2.3.4-r0","2.3.4-r1","2.3.4-r2","2.3.5-r0","2.5.1-r0","2.5.2-r0","2.5.2-r1","2.5.3-r0","2.5.4-r0","2.6.1-r0","2.6.2-r0","2.6.2-r1","2.6.2-r2","2.6.3-r0","2.7-r0","2.7.1-r0","2.7.1-r1","2.7.2-r0","2.8-r0","2.8-r1","2.8-r2","2.8.1-r0","2.8.2-r0","2.8.2-r1","2.8.3-r0","2.8.5-r0","3.0.1-r0","3.0.2-r0","3.0.2-r1","3.1-r0","3.1.1-r0","3.1.2-r0","3.1.3-r0","3.1.4-r0","3.1.6-r0","3.1.7-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14171.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.6","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.8-r0"}]}],"versions":["0.10-r0","0.10-r1","0.10-r2","0.10.2-r0","0.11-r0","0.11.1-r0","0.11.1-r1","0.11.2-r1","0.5-r0","0.6-r0","0.6-r1","0.6-r2","0.6.1-r0","0.6.1-r1","0.6.2-r0","0.6.2-r1","0.6.2-r2","0.6.3-r0","0.6.3-r1","0.6.3-r2","0.8-r0","0.8.1-r0","0.8.2-r0","0.8.3-r0","0.8.4-r0","0.8.5-r0","0.8.5-r1","0.8.6-r0","0.8.7-r0","0.9-r0","0.9.1-r0","1.0-r0","1.0-r1","1.0-r2","1.0.1-r0","1.0.1-r1","1.1-r1","1.1.2-r1","1.1.2-r2","1.1.2-r3","1.1.3-r0","1.1.4-r0","1.2-r0","1.2-r1","1.2.1-r0","1.2.2-r0","1.2.4-r0","2.0.2-r0","2.1-r0","2.1.1-r0","2.1.3-r0","2.1.4-r0","2.2-r0","2.2.2-r0","2.2.3-r0","2.2.4-r0","2.2.4-r1","2.2.4-r2","2.2.4-r3","2.3-r0","2.3.1-r0","2.3.2-r0","2.3.3-r0","2.3.4-r0","2.3.4-r1","2.3.4-r2","2.3.5-r0","2.5.1-r0","2.5.2-r0","2.5.2-r1","2.5.3-r0","2.5.4-r0","2.6.1-r0","2.6.2-r0","2.6.2-r1","2.6.2-r2","2.6.3-r0","2.7-r0","2.7.1-r0","2.7.1-r1","2.7.2-r0","2.8-r0","2.8-r1","2.8-r2","2.8.1-r0","2.8.2-r0","2.8.2-r1","2.8.3-r0","2.8.5-r0","3.0.1-r0","3.0.2-r0","3.0.2-r1","3.1-r0","3.1.1-r0","3.1.2-r0","3.1.3-r0","3.1.4-r0","3.1.6-r0","3.2.2-r0","3.2.2-r1","3.2.4-r0","3.2.4-r1","3.2.6-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2017-14171.json"}},{"package":{"name":"ffmpeg","ecosystem":"Alpine:v3.7","purl":"pkg:apk/alpine/ffmpeg?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.4-r0"}]}],"versions":["0.10-r0","0.10-r1","0.10-r2","0.10.2-r0","0.11-r0","0.11.1-r0","0.11.1-r1","0.11.2-r1","0.5-r0","0.6-r0","0.6-r1","0.6-r2","0.6.1-r0","0.6.1-r1","0.6.2-r0","0.6.2-r1","0.6.2-r2","0.6.3-r0","0.6.3-r1","0.6.3-r2","0.8-r0","0.8.1-r0","0.8.2-r0","0.8.3-r0","0.8.4-r0","0.8.5-r0","0.8.5-r1","0.8.6-r0","0.8.7-r0","0.9-r0","0.9.1-r0","1.0-r0","1.0-r1","1.0-r2","1.0.1-r0","1.0.1-r1","1.1-r1","1.1.2-r1","1.1.2-r2","1.1.2-r3","1.1.3-r0","1.1.4-r0","1.
