{"id":"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":"2026-04-16T01:43:11.463042909Z","published":"2017-09-07T06:29:00.297Z","related":["openSUSE-SU-2024:10754-1"],"references":[{"type":"WEB","url":"http://www.securityfocus.com/bid/100706"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2019/01/msg00006.html"},{"type":"ADVISORY","url":"http://www.debian.org/security/2017/dsa-3996"},{"type":"ADVISORY","url":"https://github.com/FFmpeg/FFmpeg/commit/c24bcb553650b91e9eff15ef6e54ca73de2453b7"},{"type":"REPORT","url":"https://github.com/FFmpeg/FFmpeg/commit/c24bcb553650b91e9eff15ef6e54ca73de2453b7"},{"type":"FIX","url":"https://github.com/FFmpeg/FFmpeg/commit/c24bcb553650b91e9eff15ef6e54ca73de2453b7"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ffmpeg/ffmpeg","events":[{"introduced":"0"},{"fixed":"c24bcb553650b91e9eff15ef6e54ca73de2453b7"}]}],"versions":["N","n0.11-dev","n0.12-dev","n0.8","n1.1-dev","n1.2-dev","n1.3-dev","n2.0","n2.1-dev","n2.2-dev","n2.3-dev","n2.4-dev","n2.5-dev","n2.6-dev","n2.7-dev","n2.8-dev","n2.9-dev","n3.1-dev","n3.2-dev","n3.3-dev","n3.4-dev"],"database_specific":{"vanir_signatures":[{"digest":{"length":2647,"function_hash":"272674515123442855883014561025808090604"},"id":"CVE-2017-14171-352474f8","signature_version":"v1","deprecated":false,"source":"https://github.com/ffmpeg/ffmpeg/commit/c24bcb553650b91e9eff15ef6e54ca73de2453b7","signature_type":"Function","target":{"function":"nsv_parse_NSVf_header","file":"libavformat/nsvdec.c"}},{"digest":{"line_hashes":["163700682919203254672523376235181754336","313333650659292797870983492868699436327","104703890762874859995521295993227348633","77526834729182645364472304687455895246","57775010657314048499270854018607517522"],"threshold":0.9},"id":"CVE-2017-14171-942d45fb","signature_version":"v1","deprecated":false,"signature_type":"Line","source":"https://github.com/ffmpeg/ffmpeg/commit/c24bcb553650b91e9eff15ef6e54ca73de2453b7","target":{"file":"libavformat/nsvdec.c"}}],"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-14171.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"}]}
