Hi,

In a post to bugtraq yesterday I posted patches to the unix vncviewer
which turns it in a cracker by doing dictionary attacks on the
(win)VNC server.

Please note that WinVNC since version 3.3.3R6 incorporates code
that makes attacks like described in my previous post much harder.
Version 3.3.3R6 which was released at may 15, 2000. Please update
your server, use strong passwords and apply the AuthHosts
and QuerySetting registry settings if possible.

It can be gotten at http://www.uk.research.att.com/vnc/.
See http://www.uk.research.att.com/vnc/winhistory.html for what
has been changed.

        Patrick
