The greatest threat to the system was confidentiality and integrity. (BZ#1918750)</li> <li> 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. (BZ#1936407)</li> You may download the oc tool and use it to inspect release image metadata<br>as follows:<br>(For x86_64 architecture)<br>$ oc adm release info<br>quay.io/openshift-release-dev/ocp-release:4.6.20-x86_64<br>The image digest is<br>sha256:999a6a4bd731075e389ae601b373194c6cb2c7b4dadd1ad06ef607e86476b129<br>(For s390x architecture)<br>$ oc adm release info<br>quay.io/openshift-release-dev/ocp-release:4.6.20-s390x<br>The image digest is<br>sha256:90be6b7e97d8da9fbb2afc7fe6d7dd4da6265fb847ec440e46bda1a25c224b0c<br>(For ppc64le architecture)<br>$ oc adm release info<br>quay.io/openshift-release-dev/ocp-release:4.6.20-ppc64le<br>The image digest is<br>sha256:475367e4991d6e8ea3617cf3dfe2dd472db76a89f23484f118932d6bdd6f53e9<br>Security Fix(es):<br><li> golang: crypto/elliptic: incorrect operations on the P-224 curve (CVE-2021-3114)</li> 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.<br>All OpenShift Container Platform 4.7 users are advised to upgrade to these<br>updated packages and images when they are available in the appropriate<br>release channel.
