This occurs because of file-descriptor mishandling, related to /proc/self/exe.","published":"2019-02-11T19:29:00.000Z","lastModified":"2026-06-17T02:38:08.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},"cwe":["CWE-78"],"affected":["docker/docker","linuxfoundation/runc","redhat/container development kit","redhat/openshift","redhat/enterprise linux","redhat/enterprise linux server","google/kubernetes engine","linuxcontainers/lxc","hp/onesphere","netapp/hci management node","netapp/solidfire","apache/mesos","opensuse/backports sle","opensuse/leap","d2iq/kubernetes engine","d2iq/dc\\/os","fedoraproject/fedora","canonical/ubuntu linux","microfocus/service management automation"],"epss":{"score":0.98452,"percentile":0.99919,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":2,"verified":false,"firstPublished":"2019-02-12","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":46369,"kind":"exploit","title":"runc < 1.0-rc6 (Docker < 18.09.2) - Container Breakout (2)","url":"https://www.exploit-db.com/exploits/46369","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux/local/46369.md","file":"exploits/linux/local/46369.md","published":"2019-02-13","added":"2019-02-14","updated":"2019-02-14","author":"embargo","type":"local","platform":"linux","port":null,"verified":false,"codes":["CVE-2019-5736"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://www.openwall.com/lists/oss-security/2019/02/13/3"},{"edbId":46359,"kind":"exploit","title":"runc < 1.0-rc6 (Docker < 18.09.2) - Container Breakout (1)","url":"https://www.exploit-db.com/exploits/46359","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux/local/46359.md","file":"exploits/linux/local/46359.md","published":"2019-02-12","added":"2019-02-12","updated":"2019-02-14","author":"feexd","type":"local","platform":"linux","port":null,"verified":false,"codes":["CVE-2019-5736"],"tags":"Local","aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://github.com/feexd/pocs/tree/a5aac58e0935a505c034b5f9e6cf35c1fc67471d/CVE-2019-5736"}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 98.5%, higher than 100% of all known CVEs.
