What vulnerabilities could there be in a packet logger?

[iago]

It has parsers for various protocols (TCP, UDP, IPX, AIM, MSN, HTTP, FTP, and probably a hundred others).  It parses the packets when it sees them in a way that can be prettily displayed.  Many of the protocol parsers had vulnerabilities if they aren't properly formed.
