When a crafted RL2 file, which claims a large \"frame_count\" field in the header but does not contain sufficient backing data, is provided, the loops (for offset and size tables) would consume huge CPU and memory resources, since there is no EOF check inside these loops.","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/100628","https://github.com/FFmpeg/FFmpeg/commit/96f24d1bee7fe7bac08e2b7c74db1a046c9dc0de","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-2017-14056","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).
