An attacker takes advantage of the structure of integer variables to cause
						these variables to assume values that are not expected by an application.
						For example, adding one to the largest positive integer in a signed integer
						variable results in a negative number. Negative numbers may be illegal in an
						application and the application may prevent an attacker from providing them
						directly, but the application may not consider that adding two positive
						numbers can create a negative number do to the structure of integer storage
						formats.
