{"id":"UBUNTU-CVE-2018-12608","details":"An issue was discovered in Docker Moby before 17.06.0. The Docker engine validated a client TLS certificate using both the configured client CA root certificate and all system roots on non-Windows systems. This allowed a client with any domain validated certificate signed by a system-trusted root CA (as opposed to one signed by the configured CA root certificate) to authenticate.","modified":"2025-09-08T16:44:55Z","published":"2018-09-10T17:29:00Z","upstream":["CVE-2018-12608"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-12608"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-12608"}],"affected":[{"package":{"name":"docker.io","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/docker.io@18.06.1-0ubuntu1~16.04.2?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.06.1-0ubuntu1~16.04.2"}]}],"versions":["1.6.2~dfsg1-1ubuntu4","1.10.2-0ubuntu3","1.10.2-0ubuntu4","1.10.3-0ubuntu1","1.10.3-0ubuntu4","1.10.3-0ubuntu5","1.10.3-0ubuntu6","1.11.2-0ubuntu5~16.04","1.12.1-0ubuntu13~16.04.1","1.12.3-0ubuntu4~16.04.2","1.12.6-0ubuntu1~16.04.1","1.13.1-0ubuntu1~16.04.2","17.03.2-0ubuntu2~16.04.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"18.06.1-0ubuntu1~16.04.2","binary_name":"docker.io"},{"binary_version":"18.06.1-0ubuntu1~16.04.2","binary_name":"golang-docker-dev"},{"binary_version":"18.06.1-0ubuntu1~16.04.2","binary_name":"golang-github-docker-docker-dev"},{"binary_version":"18.06.1-0ubuntu1~16.04.2","binary_name":"vim-syntax-docker"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-12608.json"}},{"package":{"name":"docker.io","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/docker.io@18.06.1-0ubuntu1~18.04.1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.06.1-0ubuntu1~18.04.1"}]}],"versions":["1.13.1-0ubuntu6","17.03.2-0ubuntu1","17.03.2-0ubuntu3","17.03.2-0ubuntu5","17.12.1-0ubuntu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"18.06.1-0ubuntu1~18.04.1","binary_name":"docker.io"},{"binary_version":"18.06.1-0ubuntu1~18.04.1","binary_name":"golang-docker-dev"},{"binary_version":"18.06.1-0ubuntu1~18.04.1","binary_name":"golang-github-docker-docker-dev"},{"binary_version":"18.06.1-0ubuntu1~18.04.1","binary_name":"vim-syntax-docker"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-12608.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"low"}]}
