Hey look at this fun little message from bugtraq:
Problem:
Trillian's irc modules suffers from a buffer overflow. This allows an attacker to execute code of their choice. I have attempted to contact the trillian developers about this issue with no success.
Aww, that sucks. And he even included the exploit code....

Oh wait, whats this....another message from bugtraq....
Vulnerability : Format strings bug and buffer overflow in the IRC client of Trillian
Wait, that looks like 2 more vulnerabilities. At least he didn't include an exploit for all the script kiddies....

And people always ask me why I don't like that program.....Hummm...
