✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible. Workaround: To mitigate this flaw, ensure that Redis replicas maintain `replica-read-only` as enabled and prevent its modification by unauthorized users. If Lua scripting is not a required feature, consider disabling it to reduce the attack surface. Restricting network access to Redis instances to trusted clients can also limit exposure. For Redis configuration, edit the `redis.conf` file to include or verify: `replica-read-only yes` After modifying the configuration, restart the Redis service for the changes to take effect. This action will temporarily interrupt service availability. Workaround: To mitigate this flaw, restrict the execution privileges of the RESTORE command exclusively to highly trusted and administrative users by using the appropriate ACL rules.
