{"id":"GHSA-gp4j-w3vj-7299","summary":"Information Exposure in RunC","details":"RunC allowed additional container processes via 'runc exec' to be ptraced by the pid 1 of the container.  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.","aliases":["CVE-2016-9962","GO-2022-0835"],"modified":"2026-07-17T21:09:48.918080146Z","published":"2021-12-20T18:21:43Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2021-05-20T16:22:33Z","nvd_published_at":null,"cwe_ids":["CWE-200"],"severity":"MODERATE"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2016-9962"},{"type":"WEB","url":"https://github.com/opencontainers/runc/commit/50a19c6ff828c58e5dab13830bd3dacde268afe5"},{"type":"WEB","url":"https://github.com/opencontainers/runc/commit/5d93fed3d27f1e2bab58bad13b180a7a81d0b378"},{"type":"WEB","url":"https://access.redhat.com/security/vulnerabilities/cve-2016-9962"},{"type":"WEB","url":"https://bugzilla.suse.com/show_bug.cgi?id=1012568#c6"},{"type":"WEB","url":"https://github.com/docker/docker/releases/tag/v1.12.6"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BQAXJMMLRU7DD2IMG47SR2K4BOFFG7FZ"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/FINGBFMIXBG6B6ZWYH3TMRP5V3PDBNXR"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/UVM7FCOQMPKOFLDTUYSS4ES76DDM56VP"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/WUQ3MQNEL5IBZZLMLR72Q4YDCL2SCKRK"},{"type":"WEB","url":"https://security.gentoo.org/glsa/201701-34"},{"type":"WEB","url":"https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-9962"},{"type":"WEB","url":"http://rhn.redhat.com/errata/RHSA-2017-0116.html"},{"type":"WEB","url":"http://rhn.redhat.com/errata/RHSA-2017-0123.html"},{"type":"WEB","url":"http://rhn.redhat.com/errata/RHSA-2017-0127.html"},{"type":"WEB","url":"http://seclists.org/fulldisclosure/2017/Jan/21"},{"type":"WEB","url":"http://seclists.org/fulldisclosure/2017/Jan/29"},{"type":"WEB","url":"http://www.securityfocus.com/archive/1/540001/100/0/threaded"},{"type":"WEB","url":"http://www.securityfocus.com/bid/95361"}],"affected":[{"package":{"name":"github.com/opencontainers/runc","ecosystem":"Go","purl":"pkg:golang/github.com/opencontainers/runc"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.0.0-rc3"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 1.0.0-rc2","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/12/GHSA-gp4j-w3vj-7299/GHSA-gp4j-w3vj-7299.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
