✅ Remediation

For OpenShift Container Platform 4.14 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/4.14/html/release_notes/ Workaround: Upgrade to a fixed golang.org/x/net release that includes the idna correction, via updated golang or dependent package rebuilds. Workaround: To mitigate this issue, ensure that the environment where the openshift-ansible installer container is executed is secured against network Man-in-the-Middle (MITM) attacks. When using the `INVENTORY_URL` or `DYNAMIC_SCRIPT_URL` environment variables, always provide URLs that use HTTPS to a trusted server and verify the server's certificate. If possible, avoid using remote inventory scripts and instead provide local inventory files to the installer.
