{"id":"CVE-2019-5736","details":"runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.","modified":"2026-05-08T04:37:57.714416Z","published":"2019-02-11T19:29:00.297Z","related":["ALSA-2019:0975","CGA-6f3p-hv3h-6gmw","SUSE-SU-2019:0362-1","SUSE-SU-2019:0385-1","SUSE-SU-2019:0495-1","SUSE-SU-2019:0573-1","SUSE-SU-2019:1234-1","SUSE-SU-2019:1234-2","SUSE-SU-2019:2117-1","SUSE-SU-2019:2119-1","SUSE-SU-2021:1458-1","openSUSE-SU-2019:0170-1","openSUSE-SU-2019:0208-1","openSUSE-SU-2019:0252-1","openSUSE-SU-2019:0295-1","openSUSE-SU-2019:1227-1","openSUSE-SU-2019:1275-1","openSUSE-SU-2019:1444-1","openSUSE-SU-2019:1499-1","openSUSE-SU-2019:1506-1","openSUSE-SU-2019:2021-1","openSUSE-SU-2019:2245-1","openSUSE-SU-2019:2286-1","openSUSE-SU-2024:10693-1","openSUSE-SU-2024:10762-1","openSUSE-SU-2024:11030-1","openSUSE-SU-2024:11358-1"],"database_specific":{"unresolved_ranges":[{"cpe":"cpe:2.3:a:apache:mesos:*:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"introduced":"1.4.0"},{"fixed":"1.4.3"},{"introduced":"1.5.0"},{"fixed":"1.5.3"},{"introduced":"1.6.0"},{"fixed":"1.6.2"},{"introduced":"1.7.0"},{"fixed":"1.7.2"}]},{"cpe":"cpe:2.3:a:d2iq:kubernetes_engine:*:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"fixed":"2.2.0-1.13.3"}]},{"cpe":"cpe:2.3:a:docker:docker:*:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"fixed":"18.09.2"}]},{"cpe":"cpe:2.3:a:linuxcontainers:lxc:*:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"fixed":"3.2.0"}]},{"cpe":"cpe:2.3:a:microfocus:service_management_automation:2018.02:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"2018.02"}]},{"cpe":"cpe:2.3:a:microfocus:service_management_automation:2018.05:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"2018.05"}]},{"cpe":"cpe:2.3:a:microfocus:service_management_automation:2018.08:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"2018.08"}]},{"cpe":"cpe:2.3:a:microfocus:service_management_automation:2018.11:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"2018.11"}]},{"cpe":"cpe:2.3:a:opensuse:backports_sle:15.0:-:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"15.0-NA"}]},{"cpe":"cpe:2.3:a:opensuse:backports_sle:15.0:sp1:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"15.0-sp1"}]},{"cpe":"cpe:2.3:a:redhat:openshift:3.4:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"3.4"}]},{"cpe":"cpe:2.3:a:redhat:openshift:3.5:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"3.5"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"16.04"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"18.04"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:18.10:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"18.10"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:19.04:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"19.04"}]},{"cpe":"cpe:2.3:o:d2iq:dc\\/os:*:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"fixed":"1.10.10"},{"introduced":"1.10.11"},{"fixed":"1.11.9"},{"introduced":"1.11.10"},{"fixed":"1.12.1"}]},{"cpe":"cpe:2.3:o:fedoraproject:fedora:29:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"29"}]},{"cpe":"cpe:2.3:o:fedoraproject:fedora:30:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"30"}]},{"cpe":"cpe:2.3:o:opensuse:leap:15.0:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"15.0"}]},{"cpe":"cpe:2.3:o:opensuse:leap:15.1:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"15.1"}]},{"cpe":"cpe:2.3:o:opensuse:leap:42.3:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"42.3"}]},{"cpe":"cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"8.0"}]},{"cpe":"cpe:2.3:o:redhat:enterprise_linux_server:7.0:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"7.0"}]}]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/01/31/6"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/02/01/1"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2024/02/02/3"},{"type":"WEB","url":"https://lists.apache.org/thread.html/24e54e3c6b2259e3903b6b8fe26896ac649c481ea99c5739468c92a3%40%3Cdev.dlab.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/a258757af84c5074dc7bf932622020fd4f60cef65a84290380386706%40%3Cuser.mesos.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/a585f64d14c31ab393b90c5f17e41d9765a1a17eec63856ce750af46%40%3Cdev.dlab.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/acacf018c12636e41667e94ac0a1e9244e887eef2debdd474640aa6e%40%3Cdev.dlab.apache.org%3E"},{"type":"WEB","url":"https://lis
