Description

This is an exploit for the Poptop negative read overflow. This will
work against versions prior to 1.1.3-b3 and 1.1.3-20030409, but I
currently do not have a good way to detect Poptop versions.

The server will by default only allow 4 concurrent manager processes
(what we run our code in), so you could have a max of 4 shells at once.

Using the current method of exploitation, our socket will be closed
before we have the ability to run code, preventing the use of Findsock.
