# Winamp 5.12 Playlist UNC Path Computer Name Overflow Perl Exploit
# By Umesh Wanve (umesh_345@yahoo.com)
# ===========================================================================================================================
# 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.
