The software does not check or improperly checks for unusual or
					exceptional conditions that are not expected to occur frequently during day to
					day operation of the software.The programmer may assume that certain events or conditions will never
						occur or do not need to be worried about, such as low memory conditions,
						lack of access to resources due to restrictive permissions, or misbehaving
						clients or components. However, attackers may intentionally trigger these
						unusual conditions, thus violating the programmer's assumptions, possibly
						introducing instability, incorrect behavior, or a vulnerability.Note that this entry is not exclusively about the use of exceptions and
						exception handling, which are mechanisms for both checking and handling
						unusual or unexpected conditions.
