{"id":"CVE-2017-14223","details":"In libavformat/asfdec_f.c in FFmpeg 3.3.3, a DoS in asf_build_simple_index() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted ASF file, which claims a large \"ict\" field in the header but does not contain sufficient backing data, is provided, the for loop would consume huge CPU and memory resources, since there is no EOF check inside the loop.","modified":"2026-08-17T05:25:47.802277Z","published":"2017-09-09T01:29:02.767Z","related":["openSUSE-SU-2024:10754-1"],"database_specific":{"unresolved_ranges":[{"vendor_product":"debian:debian_linux","cpes":["cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"8.0"},{"last_affected":"8.0"},{"introduced":"9.0"},{"last_affected":"9.0"}],"source":"CPE_STRING"}]},"references":[{"type":"ADVISORY","url":"http://www.debian.org/security/2017/dsa-3996"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/100703"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/02/msg00005.html"},{"type":"FIX","url":"https://github.com/FFmpeg/FFmpeg/commit/afc9c683ed9db01edb357bc8c19edad4282b3a97"}],"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-2017-14223.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/ffmpeg/ffmpeg","events":[{"introduced":"9079c70d2095643af6954001d0627445650b85a6"},{"last_affected":"9079c70d2095643af6954001d0627445650b85a6"},{"fixed":"afc9c683ed9db01edb357bc8c19edad4282b3a97"}],"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":{"vanir_signatures_modified":"2026-08-17T05:25:47Z","vanir_signatures":[{"id":"CVE-2017-14223-b2b0989d","signature_type":"Function","signature_version":"v1","source":"https://github.com/ffmpeg/ffmpeg/commit/afc9c683ed9db01edb357bc8c19edad4282b3a97","target":{"function":"asf_build_simple_index","file":"libavformat/asfdec_f.c"},"deprecated":false,"digest":{"function_hash":"298941566614919344677850767521217841045","length":1581}},{"source":"https://github.com/ffmpeg/ffmpeg/commit/afc9c683ed9db01edb357bc8c19edad4282b3a97","target":{"file":"libavformat/asfdec_f.c"},"deprecated":false,"digest":{"line_hashes":["87977252985728327265785999907427570066","81041191235438376294380721571413715694","214057754302444418590177466812680093676"],"threshold":0.9},"id":"CVE-2017-14223-d276890a","signature_type":"Line","signature_version":"v1"}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-14223.json"}}],"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"}]}
