✅ Remediation
For OpenShift Container Platform 4.15 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.openshift.com/container-platform/4.15/release_notes/ocp-4-15-release-notes.html 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 (For x86_64 architecture) The image digest is sha256:f0787207e687538a2d1248f2956b5bd26e304334eeb2f6474833040063377e9a (For s390x architecture) The image digest is sha256:483f95c386a24778ea807286fac3a1b702787893a265305dfd6af13f0cf85645 (For ppc64le architecture) The image digest is sha256:27b5b20aa2f76345c7fedc4cea350a3fa37f055472a260d7c971a1bb62dbd2b0 (For aarch64 architecture) The image digest is sha256:b24c0158d257fdf06277d68656c29c8ec3abdea2905801a721f606a024568c8f All OpenShift Container Platform 4.15 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.openshift.com/container-platform/4.15/updating/updating_a_cluster/updating-cluster-cli.html Workaround: The below process can protect against a Remote Code Execution attack by disabling the LoginGraceTime parameter on Red Hat Enterprise Linux 9. However, the sshd server is still vulnerable to a Denial of Service if an attacker exhausts all the connections. 1) As root user, open the /etc/ssh/sshd_config 2) Add or edit the parameter configuration: ~~~ LoginGraceTime 0 ~~~ 3) Save and close the file 4) Restart the sshd daemon: ~~~ systemctl restart sshd.service ~~~ Setting LoginGraceTime to 0 disables the SSHD server's ability to drop connections if authentication is not completed within the specified timeout. If this mitigation is implemented, it is highly recommended to use a tool like 'fail2ban' alongside a firewall to monitor log files and manage connections appropriately. If any of the mitigations mentioned above is used, please note that the removal of LoginGraceTime parameter from sshd_config is not automatic when the updated package is installed.
