✅ Remediation

For OpenShift Container Platform 4.20 see the following documentation, which will be updated shortly for this release, for important instructions on how to upgrade your cluster and fully apply this asynchronous errata update: https://docs.redhat.com/en/documentation/openshift_container_platform/4.20/html/release_notes/ You may download the oc tool and use it to inspect release image metadata for x86_64, s390x, ppc64le, and aarch64 architectures. The image digests may be found at https://quay.io/repository/openshift-release-dev/ocp-release?tab=tags. The sha values for the release are as follows: (For x86_64 architecture) The image digest is sha256:a29bcbc9f286d68b394ffa0288c5de7e487c90077c06cbaf7a4cadeb0398ce28 (For s390x architecture) The image digest is sha256:724ea94541fa32defeae6a782fb2f1194e5bd7221ec33d7bcc6c4dc1e53cabc3 (For ppc64le architecture) The image digest is sha256:125ba716fa99fd8dbf33a8407030ad06704cd394dfc4898f7d6fb69e1bc9a8cd (For aarch64 architecture) The image digest is sha256:38a6732d5a3485f145657156e3c0625c21aa0af16c49959dd97eec75bfb1706e All OpenShift Container Platform 4.20 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshift_container_platform/4.20/html-single/updating_clusters/index#updating-cluster-cli. Workaround: To mitigate this flaw, ensure YAML files are formatted as Helm expects prior to processing them with Helm. Workaround: To mitigate this flaw, ensure all Helm charts do not have any reference of $ref pointing to /dev/zero.
