When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","score":7.3},"cwes":["CWE-20"],"references":["https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14866","https://lists.debian.org/debian-lts-announce/2023/06/msg00007.html","https://lists.gnu.org/archive/html/bug-cpio/2019-08/msg00003.html","https://lists.gnu.org/archive/html/bug-cpio/2019-11/msg00000.html","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14866"],"products":["gnu:cpio","redhat:enterprise_linux"],"source":"nvd","synced_at":"2026-10-19T21:01:01.339895972+00:00"},"epss":{"cve":"CVE-2019-14866","score":0.00686,"percentile":0.52668,"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).
