This advisory contains the container images for Red Hat OpenShift Container Platform 4.7.4. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHSA-2021:0958 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/4.7/release_notes/ocp-4-7-rel ease-notes.html This update fixes the following bugs among others:

• A flaw was found in golang: crypto/elliptic, in which P-224 keys as generated could return incorrect inputs, which reduced the strength of the cryptography. The greatest threat to the system was confidentiality and integrity. (BZ#1918750)
• This update adds new capabilities to the Baremetal Operator, allowing for different reboot modes to be utilized. This allows workloads to be relocated as quickly as possible in the event of a node failure. Additionally, it provides a path for clients to quickly power down systems for remediation purposes and to recover workloads. As a result, workload recovery time is significantly reduced.
