Hash: SHA1

Well this is an embarrassing release for certain, turns out there was a
nasty little bug in the CAPAB handling code that allows for a remote
attacker to crash the ircd.  With that said, all admins are urged to
upgrade to ircd-ratbox-3.0.8 immediately.  See the link below for further
details, the link mentions Charybdis but really this impacts all ircd-ratbox
derived ircds.  


If you happen to be running a vunerable server and for whatever reason
cannot upgrade immediately, a /quote modunload m_capab.so should mitigate
the effects of the bug.
