There's a small bug in the latest BitchX in which a nasty user can invite
you to a channel with a %s in it, causing the client to coredump. As alot
of channels/users on irc use the client, I felt I should post a notice
about this problem. A small patch is available on
www.bitchx.com/downloads.html as well as on
   ftp.bitchx.com/pub/BitchX/1.0c16.patch

This is a classic case of printf(variable); where variable contains
formatting chars. I doubt very much this would lead to a root exploit,
anyone running any irc client as root, should be examined professionally.

I wish to thank the person who discovered this and reported it to #bitchx
on efnet, as well as the many emails I received on this subject. We had a
patch available for this before it widely known..
