Yup, and probably Bugtraq, too.

The subject: line says /ignore, I assume this problem only occurs
with /invite? (I don't use IRC much. /ignore wouldn't send
anything to the ignored party, would it?)
As a general question for vuln-dev:
I've seen a number of these print string vulnerabilities pop up
lately. I gather that the programmer writes their printf or equiv
wrong, and these attacks are getting interpreted as formatting strings
somehow.
Can someone explain to me what goes on on a stack level? Are these
exploitable (pushing code) instead of just crashing?
