When a crafted MV file, which claims a large \"nb_frames\" field in the header but does not contain sufficient backing data, is provided, the loop over the frames would consume huge CPU and memory 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/100626","https://github.com/FFmpeg/FFmpeg/commit/4f05e2e2dc1a89f38cd9f0960a6561083d714f1e","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-2017-14055","score":0.01822,"percentile":0.78766,"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).
