An update for openshift is now available for Red Hat OpenShift Container Platform 4.1. Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the openshift container images for Red Hat OpenShift Container Platform 4.1.24. Security Fix(es): * A flaw was found in kubectl that leaves http-cache files with read/write permissions for any user. In conjunction with a non-default value for --cache-dir, this could lead to the cache content being placed in a location accessible to other users in the system.
