✅ Remediation

For Red Hat Advanced Cluster Management for Kubernetes, 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://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.4/html/release_notes/index For details on how to apply this update, refer to: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.4/html-single/install/index#installing Workaround: Customers should make an attempt to run current binaries/architectures and not rely on compatibility layers to run older binaries/architectures. In case older binaries/architectures are needed, sandboxing should be used to address such problems and guard the bug. Workaround: Prevent users from executing Lua scripts. This can be done using ACL to restrict EVAL and EVALSHA commands. Please see https://redis.io/topics/acl for more information on how to do this. Workaround: The flaw can be mitigated by disallowing usage of the CONFIG SET command via ACL configuration. This will prevent clients from setting the `proto-max-bulk-len` configuration parameter. Please see https://redis.io/topics/acl for more information on how to do this. Workaround: The flaw can be mitigated by disallowing usage of the CONFIG SET command via ACL configuration. This will prevent clients from setting the above configuration parameters. Please see https://redis.io/topics/acl for more information on how to do this. Workaround: Prevent unauthenticated users from connecting to Redis by using network access control tools (e.g., firewalls) or enabling TLS and requiring users to authenticate using client side certificates. Workaround: The flaw can be mitigated by disallowing usage of the CONFIG SET command via ACL configuration. This will prevent clients from setting the `set-max-intset-entries` configuration parameter. Please see https://redis.io/topics/acl for more information on how to do this.
