Error

An error is usually caused by incorrect input from the user, or a software bug. It can be displayed as a dialog or as a full screen error in serious cases.

Security holes
Also known as a "vulnerability", which means an weakness in a system (often a dynamic web application), that allows potential attackers to gain access to places they do not belong, for example.

Memory leaks
A memory leak is an unintentional consumption of memory, caused by an program that fails to release memory once not needed any more. Serious memory leaks can cause instability issues with the computer (and in the worst cases, even crash it.)

Game cheats
Some game cheats are based on errors in the game's code that can allow the user to obtain a advantage over other players or the computer that may not be desired. These are called "glitches" more often.
