✅ Remediation

For OpenShift Container Platform 4.5 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/4.5/release_notes/ocp-4-5-release-notes.html Details on how to access this content are available at https://docs.openshift.com/container-platform/4.5/updating/updating-cluster-cli.html. Workaround: 1.SSL/TLS configurations should prefer AES over DES. Versions of OpenSSL shipped with Red Hat Enterprise Linux 6 and 7 already do so. In the version of OpenSSL shipped with Red Hat Enterprise Linux 5, 3DES is listed below the AES-256 cipher and above the AES-128 cipher, therefore AES-256 based ciphersuite should not be disabled on the server. 2. Servers using OpenSSL, should not disable AES-128 and AES-256 ciphersuites. Versions of Apache shipped with Red Hat Enterprise Linux use the default cipher string, in which AES is preferred over DES/3DES based ciphersuites. For JBoss Middleware, and Java mitigations, please review this knowledge base article: https://access.redhat.com/articles/2598471 This can be mitigated on OpenShift Container Platform (OCP) by disabling the vulnerable TLS cipher suite in the applicable component. TLS configuration options for OCP are described here: https://access.redhat.com/articles/5348961
