This kind of exploit, a local privilege escalation exploit, used to be very significant, but is significant in a declining number of cases, as old-style Unix multiuser systems are a smaller and smaller proportion of systems. In all likelihood anyone with a user account on a North Korean computer is pretty heavily monitored, and ensuring nobody violates policy can be enforced by "other means" than Unix permissions.
