IP Overlapping Fragments (Teardrop) Attack
Triggers when two fragments contained
within the same IP datagram have offsets that
indicate that they share positioning within the
datagram. This could mean that 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,
which is how the Teardrop attack works to
create a DoS.
