Deadlock causes multiple threads to not be able to progress and thus halt the executing program. This is a potential denial-of-service attack when the attacker can force deadlock situations. It's probable that deadlock will occur in multi-thread programs that manage multiple resources. Some automation for detecting deadlock can be implemented in which the detector can try different input inputs and wait for a timeout. The fixes can be done automatically using some graph algorithm like Dijkstra, but most like be manual.
