The software reads or writes to a buffer using an index or
					pointer that references a memory location after the end of the buffer. This typically occurs when a pointer or its index is decremented to a
						position before the buffer, when pointer arithmetic results in a position
						before the beginning of the valid memory location, or when a negative index
						is used. These problems may be resultant from missing sentinel values
						(CWE-463) or trusting a user-influenced input length variable.
