===IP fragment overlapped===
The IP fragment overlapped [[exploit (computer security)|exploit]] occurs when two fragments contained within the same IP datagram have offsets that indicate that they overlap each other in positioning within the datagram. This could mean that either fragment A is being completely overwritten by fragment B, or that fragment A is partially being overwritten by fragment B. Some operating systems do not properly handle fragments that overlap in this manner and may throw exceptions or behave in other undesirable ways upon receipt of overlapping fragments. This is the basis for the [[Teardrop attack|teardrop]] [[Denial of service]] attacks.
