Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. The -oP option is available to the exim user, and allows a denial of service because root-owned files can be overwritten.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
