# Credits : ATmaCA is credited with the discovery of this vulnerability.
#
# Date : 07-03-2007
#
# Tested on Windows 2000 SP4 Server English
#           Windows 2000 SP4 Professional English
#
# You can replace shellcode with your favourite one :)
#
# 
# Buffer = "\x90 x 1023"      +  EIP    
# 
# Desc: you cant put shellcode after EIP. No more space after this. The winamp simply crashes.  When you debug it, you will see that
#   shellcode is 304 bytes away from ESP. So jump to esp + 304 should work. Find such address if u can.
