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.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-834"],"references":["http://www.debian.org/security/2017/dsa-3996","http://www.securityfocus.com/bid/100706","https://github.com/FFmpeg/FFmpeg/commit/c24bcb553650b91e9eff15ef6e54ca73de2453b7","https://lists.debian.org/debian-lts-announce/2019/01/msg00006.html","http://www.debian.org/security/2017/dsa-3996"],"products":["ffmpeg:ffmpeg"],"source":"nvd","synced_at":"2026-10-19T20:46:01.145313090+00:00"},"epss":{"cve":"CVE-2017-14171","score":0.01768,"percentile":0.78112,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
