Somebody using a mirc exploit to kill users??

How can I fix this on my server? Seems to be using a dcc to kill people using the new version of mirc. I use Unreal on my server, version 7. Would upgrading to version 8 fix this or do I need to do something else? Anybody know?
Thanks,

Unreal has a DCC blocking feature built in. In 3.2-beta18 it is in the unrealircd.conf file. In 3.2-beta17 it is in dccdeny.conf.

This is a bug in all mirc 6.x versions.

Advice your users to do /ignore -wd *

It will ignore all dcc's on all networks.

True, though that particular DCC bug only affects all versions from 6.0 -> 6.12 (not included).

6.12 was the bug fix version. Though they found out 6.12 contained another DCC bug. They're both explained in the page Rob gave.

Also information on what to do to prevent people from crashing your mIRC with the exploits is on that page.

ctcp *:dcc send:*: if ($len($nopath($filename)) >= 225) { echo 4 -s $nick tried to crash you with an illegal dcc send of $nopath($filename) | halt }
is a better fix
