This leads to the file descriptor being inherited into the child process; the child process can then read from and write to it. This can leak sensitive information and also, if written to, be used to fill the disk or plant misinformation.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":[],"references":["http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00012.html","http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00018.html","http://www.openwall.com/lists/oss-security/2019/06/05/1","https://developers.yubico.com/pam-u2f/Release_Notes.html","https://github.com/Yubico/pam-u2f/commit/18b1914e32b74ff52000f10e97067e841e5fff62"],"products":["yubico:pam-u2f"],"source":"nvd","synced_at":"2026-10-19T20:57:00.690689396+00:00"},"epss":{"cve":"CVE-2019-12210","score":0.02056,"percentile":0.81293,"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).
