Keep in mind that both Ethreal and the MS Network Monitor had
defects that allowed malicious traffic in the packet stream being 
monitored to subvert the machine doing the sniffing. This type of 
attack wouldn't need an IP address.

That said, I suspect the basic snort engine is less complicated
than an engine needing to decode hundreds of different protocols
down to the individual field levels so there is probably less 
likelihood of undiscovered defects. I don't know if the same can 
be said for plug-ins.
