wireshark: yet another pile of dissector flaws

Serious question. Just what, exactly, is the threat vector here?

I'm not saying that it's impossible to exploit, just that it would take a seriously motivated attacker specifically targeting you for it to be worth their effort -- and that's just for a maliciously crafted capture file. If the attack involved live packet injection into your local network segment, you've already lost.

...Maybe I lack imagination or paranoia, but the only scenarios I can come up with make Schneiner's Movie Plot Challenges look downright plausible in comparison.
