✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Restrict network access to the MariaDB service so that only trusted client systems or the local host can connect. 1. If the database is only accessed locally, configure MariaDB to listen exclusively on localhost by editing `/etc/my.cnf.d/mariadb-server.cnf` under the `[mysqld]` section: ``` bind-address = 127.0.0.1 ``` Then restart the MariaDB service: ``` systemctl restart mariadb ``` 2. If remote access is necessary, use firewalld to block untrusted networks and permit access only from designated IP addresses or subnets: ``` firewall-cmd --permanent --remove-service=mariadb firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.1.0/24" service name="mariadb" accept' firewall-cmd --reload ``` Caveats: Restricting network reachability limits exposure to authorized networks and prevents untrusted network users from connecting, but it does not protect against malicious queries executed by already authenticated database accounts on permitted networks. Warning: Modifying firewall rules or binding addresses requires reloading firewall configurations or restarting the MariaDB service, which will terminate existing database connections and disrupt active services. Workaround: Upgrade to the fixed version of MariaDB Server Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
