[ This email is being sent to NZNOG and Bcc'd to about 100 people who have notified me that they are using Ihug's Time Servers. Apologies for any duplicates or errors. ] Ihug has made a small change to it's NTP servers which may affect people using them, Specifically: tk4.ihug.co.nz is going to be eliminated on 1st May 2004 tk3.ihug.co.nz had it's IP permanently moved yesterday (to 203.109.252.5) tk1.ihug.co.nz and tk2.ihug.co.nz are unchanged. If you are using tk4 then you will need to update your configuration, if you are using tk3 then you will need to ensure your NTP daemon is using it's new IP. Please use DNS of these machines in the config rather than IPs where possible. Please email me if you have any further questions. Also, If you are running a NTP server on a permanently connected machine you might want to look at joining the pool.ntp.org project , See http://www.pool.ntp.org/ for details. Currently New Zealand has around 5 servers in the project. -- Simon Lyall, | System Admin | Work: simon.lyall(a)ihug.co.nz Senior Engineer, | Network Admin | Home: simon(a)darkmere.gen.nz Ihug Ltd, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz

This so-called exploit code affects the Private Communications Transport (PCT) protocol, which is part of the Microsoft Secure Sockets Layer (SSL) library. Microsoft considers these reports credible and serious and urges all customers to immediately install <A href="x-excid://E0710000/pas:http://www.microsoft.com/technet/security/bulletin/ms04-011.mspx" target=_blank>Security Update MS4-011</A> as well as the other critical updates provided on April 13. Here is what we currently know about this issue:</P> <UL> <LI>If you are using a home computer or a non-Web server, you should install the update from <A href="x-excid://E0710000/pas:http://windowsupdate.microsoft.com/" target=_blank>Windows Update</A> to help ensure that your systems are not at risk. <LI>If you have installed and deployed Security Update MS04-011, you are <B>not</B> at risk for this issue. <LI>All programs that use SSL could be affected. Although SSL is generally associated with Internet Information Services by using HTTPS and port 443, any service that implements SSL on an affected platform is likely to be vulnerable. These services include, but are not limited to, Microsoft Internet Information Services 4.0, Microsoft Internet Information Services 5.0, Microsoft Internet Information Services 5.1, Microsoft Exchange Server 5.5, Microsoft Exchange Server 2000, Microsoft Exchange Server 2003, Microsoft Analysis Services 2000 (included with SQL ServerT 2000), and any third-party programs that use PCT. SQL Server 2000 is not vulnerable because it specifically blocks PCT connections. <LI>If you have deployed Windows XP or Windows 2000 and enabled SSL, <B>you are at risk</B>. <LI>If you have deployed Windows ServerT 2003 and enabled PCT in SSL, <B>you are at risk</B>. <LI>If you are still evaluating and testing Security Update MS04-011, you should immediately implement the mitigation steps detailed on this page.</LI></UL><PRE></FONT><A href="http://www.microsoft.com/security/incident/pctdisable.asp">http://www.microsoft.com/security/incident/pctdisable.asp</A></PRE></DIV></DIV></BODY></HTML>

Ow, my eyes. I think this is the exploit in question - also being discussed (and flamed over) on full-disclosure: http://www.k-otik.com/exploits/04212004.THCIISSLame.c.php cheers, Jamie -- James Riden / j.riden(a)massey.ac.nz / Systems Security Engineer Information Technology Services, Massey University, NZ.
