Summary: Red Hat OpenShift Container Platform release 4.4.33 is now available with updates to packages and images that fix several bugs and add enhancements. This release also includes a security update for Red Hat OpenShift Container Platform 4.4. Red Hat Product Security has rated this update as having a security impact of Important. 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. 2. Description: Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. Security Fix(es): * openshift: builder allows read and write of block devices (CVE-2021-20182) * kubernetes: Compromised node could escalate to cluster level privileges (CVE-2020-8559) * kubernetes: Docker config secrets leaked when file is malformed and loglevel >= 4 (CVE-2020-8564) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. This advisory contains the container images for Red Hat OpenShift Container Platform 4.4.33. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHSA-2021:0282 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.openshift.com/container-platform/4.4/release_notes/ocp-4-4-rel ease-notes.html This update fixes the following bugs among others: * Previously, there were broken connections to the API server that caused nodes to remain in the NotReady state. Detecting a broken network connection could take up to 15 minutes, during which the platform would remain unavailable. This is now fixed by setting the TCP_USER_TIMEOUT socket option, which controls how long transmitted data can be unacknowledged before the connection is forcefully closed. (BZ#1907939) * Previously, the quota controllers only worked on resources retrieved from the discovery endpoint, which might contain only a fraction of all resources due to a network error. This is now fixed by having the quota controllers periodically resync when new resources are observed from the discovery endpoint. (BZ#1910096) * Previously, the kuryr-controller was comparing security groups related to network policies incorrectly. This caused security rules related to a network policy to be recreated on every minor update of that network policy. This bug has been fixed, allowing network policy updates that already have existing rules to be preserved; network policy additions or deletions are performed, if needed.
