There was a critical vulnerability in Kubernetes published earlier in the week - CVE-2018-1002105. The vulnerability has been patched both the upstream project and by TUV, but the fix doesn't seem to have made it into the CentOS OpenShift build for 3.11: http://mirror.centos.org/centos/7/paas/x86_64/openshift-origin311/ The fixed version is 3.11.43, version on the mirror is 3.11.0. I'm not 100% certain of the support state of OpenShift in CentOS as it's maintained by a SIG, so what needs to happen to get the vulnerability patched for CentOS?
