{"id":"CVE-2017-14054","details":"In libavformat/rmdec.c in FFmpeg 3.3.3, a DoS in ivr_read_header() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted IVR file, which claims a large \"len\" field in the header but does not contain sufficient backing data, is provided, the first type==4 loop would consume huge CPU resources, since there is no EOF check inside the loop.","modified":"2026-08-17T05:25:46.468822Z","published":"2017-08-31T15:29:00.247Z","related":["openSUSE-SU-2024:10754-1"],"references":[{"type":"WEB","url":"http://www.securityfocus.com/bid/100627"},{"type":"ADVISORY","url":"http://www.debian.org/security/2017/dsa-3996"},{"type":"FIX","url":"https://github.com/FFmpeg/FFmpeg/commit/124eb202e70678539544f6268efc98131f19fa49"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.ffmpeg.org/ffmpeg.git","events":[{"introduced":"9079c70d2095643af6954001d0627445650b85a6"},{"last_affected":"9079c70d2095643af6954001d0627445650b85a6"}],"database_specific":{"cpe":"cpe:2.3:a:ffmpeg:ffmpeg:3.3.3:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.3.3"},{"last_affected":"3.3.3"}],"source":"CPE_STRING"}}],"versions":["3.3.3","n3.3.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-14054.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/ffmpeg/ffmpeg","events":[{"introduced":"9079c70d2095643af6954001d0627445650b85a6"},{"last_affected":"9079c70d2095643af6954001d0627445650b85a6"},{"fixed":"124eb202e70678539544f6268efc98131f19fa49"}],"database_specific":{"cpe":"cpe:2.3:a:ffmpeg:ffmpeg:3.3.3:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.3.3"},{"last_affected":"3.3.3"}],"source":["CPE_STRING","REFERENCES"]}}],"versions":["3.3.3","n3.3.3"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-14054.json","vanir_signatures_modified":"2026-08-17T05:25:46Z","vanir_signatures":[{"deprecated":false,"digest":{"line_hashes":["234032054447535025478726622637781525984","123352030564568524941742042316477844946","117292502487100815111164887830115694020","167331368778348808159532095529755586265","213900236681013805180364471646869887864"],"threshold":0.9},"id":"CVE-2017-14054-0fa15e86","signature_type":"Line","signature_version":"v1","source":"https://github.com/ffmpeg/ffmpeg/commit/124eb202e70678539544f6268efc98131f19fa49","target":{"file":"libavformat/rmdec.c"}},{"target":{"file":"libavformat/rmdec.c","function":"ivr_read_header"},"deprecated":false,"digest":{"function_hash":"131383091143261345982428874803280954829","length":3843},"id":"CVE-2017-14054-afe9400b","signature_type":"Function","signature_version":"v1","source":"https://github.com/ffmpeg/ffmpeg/commit/124eb202e70678539544f6268efc98131f19fa49"}]}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
