This allows the main processes of the container, if running as root, to gain access to file-descriptors of these new processes during the initialization and can lead to container escapes or modification of runC state before the process is fully placed inside the container.","published":"2017-01-31T22:59:01.783Z","modified":"2026-08-27T08:18:24.459092Z","cvss":{"score":6.4,"severity":"MEDIUM","vector":"CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/opencontainers/runc","fixedVersion":"1.0.0-rc3"}],"fix":{"url":"https://github.com/opencontainers/runc/commit/50a19c6ff828c58e5dab13830bd3dacde268afe5","label":"opencontainers/runc@50a19c6"},"references":[{"type":"WEB","url":"http://www.securityfocus.com/archive/1/540001/100/0/threaded"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BQAXJMMLRU7DD2IMG47SR2K4BOFFG7FZ/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FINGBFMIXBG6B6ZWYH3TMRP5V3PDBNXR/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UVM7FCOQMPKOFLDTUYSS4ES76DDM56VP/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WUQ3MQNEL5IBZZLMLR72Q4YDCL2SCKRK/"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2017-0116.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2017-0123.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2017-0127.html"},{"type":"ADVISORY","url":"http://seclists.org/fulldisclosure/2017/Jan/21"},{"type":"ADVISORY","url":"http://seclists.org/fulldisclosure/2017/Jan/29"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/95361"},{"type":"ADVISORY","url":"https://access.redhat.com/security/vulnerabilities/cve-2016-9962"},{"type":"ADVISORY","url":"https://github.com/docker/docker/releases/tag/v1.12.6"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201701-34"},{"type":"REPORT","url":"https://bugzilla.suse.com/show_bug.cgi?id=1012568#c6"},{"type":"FIX","url":"https://github.com/opencontainers/runc/commit/50a19c6ff828c58e5dab13830bd3dacde268afe5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T08:18:24.459092Z"}}
