mariadb: MariaDB: Privilege escalation via ACL cache key collision

A flaw was found in MariaDB. An issue in the Access Control List ACL cache causes identical privilege cache keys to be generated when a role and a local user share the same name. An attacker with user creation privileges can exploit this key collision by creating a matching account, allowing them...
