OpenShift Container Platform (OCP) 3.11 was too permissive in the way it specified CORS allowed origins during installation. An attacker able to man-in-the-middle the connection between the user's browser and the openshift console could use this flaw to perform a phishing attack.
During installation of an OpenShift 4 cluster, the openshift-install command line tool creates an auth directory, with kubeconfig and kubeadmin-password files. Both files contain credentials used to authenticate to the OpenShift API server, and are incorrectly assigned word-readable permissions.
In contrast, the oc command line tool creates configuration files that are only readable by the current user.
OpenShift Container Platform before version 4.1.3 writes OAuth tokens in plaintext to the audit logs for the Kubernetes API server and OpenShift API server. A user with sufficient privileges could recover OAuth tokens from these audit logs and use them to access other resources.
A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux (since version v219-62.2) and CentOS. Function dispatchmessagereal() in journald-server.c does not free the memory allocated by setiovecfieldfree() to store the CMDLINE= entry. A local attacker may use this flaw to make systemd-journald crash.
However systemd-journald crash is automatically restarted by systemd by default.
An input validation flaw was found in the way OpenShift 3 handles requests for images. A user, with a copy of the manifest associated with an image, can pull an image even if they do not have access to the image normally, resulting in the disclosure of any information contained within the image.
