Dear Valued Microsoft Customer,
We are contacting you today to make you aware that we have released Microsoft Security Bulletin MS03-039 today, September 10, 2003. This bulletin details three critical vulnerabilities in the Windows operating system and provides instructions for applying the corresponding patch. While there is currently no active exploit of this vulnerability, if successfully exploited, these vulnerabilities would allow an attacker to gain control of the target system.
We strongly encourage you to obtain and deploy this patch to any affected system that connects to your network; this includes systems on your local area network and remote or mobile systems. For the most current information on affected systems and recommended remediation steps, please read the bulletin posted at: http://www.microsoft.com/technet/security/bulletin/ms03-039.asp
We understand the potential effect this situation and the recommended remediation steps may have on you. Microsoft is committed to providing you with information and tools to help run your enterprise safely and reliably on an on-going basis. When we become aware of vulnerabilities, it is our goal to quickly share protection and remediation information and work in partnership with you to eliminate these kinds of threats to your business. In order to help protect your computing environment from security vulnerabilities, we strongly encourage you to visit http://www.microsoft.com/technet/security/protect and implement the following three steps in your enterprise:
1. Verify firewall configuration. Audit Internet and intranet firewalls to ensure they comply with your security policy; these are your first line of defense. In addition, evaluate using host-level firewalls such as the Internet Connection Firewall in Windows XP. This is especially important for systems such as laptops and home PCs that connect to your network remotely.
2. Stay up to date. Use update services from Microsoft to keep your systems up to date.
. Automatic Updates, available on Windows XP, Windows 2000 SP3 and SP4, and Windows Server 2003. Automatic Updates works with the Windows Update Web site to automate the process of updating Windows systems.
. Software Update Services (SUS), a patch-distribution server available for download from our Web site. SUS enables you deploy a server in your business that Automatic Updates clients will use to get only approved and tested patches.
In addition to using these update services, we strongly recommend that you subscribe to Microsoft's free security notification service at http://www.microsoft.com/securitynotification, so that you are proactively kept aware of new security issues.
3. Use and keep antivirus software up-to-date. Antivirus software programs will help protect your systems against many viruses, worms, Trojan horses, and other malicious code. To protect your systems from new viruses, it's also important to obtain up-to-date antivirus signatures through a subscription service from the antivirus software vendor. You should not let remote users or laptops connect to your network unless they have up-to-date antivirus software installed. In addition, consider using antivirus software in multiple points of your computer infrastructure, such as on edge Web proxy systems, as well as on email servers and gateways.
You should also protect your network by requiring employees to take the same three steps with home and laptop PCs they use to remotely connect to your enterprise, and by encouraging them to talk with friends and family to do the same with their PCs. To make this easier, we have set up a new Web site to assist PC users at http://www.microsoft.com/protect.
Again, we want to encourage you to read this security bulletin and deploy the patch to your systems. We want to thank you for your patience and work with you to protect your business from these kinds of security threats.
Thank you,
Microsoft Corporation

Microsoft Windows NT Server 4.0, Terminal Server
Edition

Microsoft encourages customers to review the Security Bulletins

Issue:
======
The fix provided by this patch supersedes the one included in
Microsoft Security Bulletin MS03-026.
Remote Procedure Call (RPC) is a protocol used by the Windows
operating system. RPC provides an inter-process communication
mechanism that allows a program running on one computer to
seamlessly access services on another computer. The protocol
itself is derived from the Open Software Foundation (OSF) RPC
protocol, but with the addition of some Microsoft specific
extensions.
There are three identified vulnerabilities in the part of RPCSS
Service that deals with RPC messages for DCOM activation- two
that could allow arbitrary code execution and one that could
result in a denial of service. The flaws result from incorrect
handling of malformed messages. These particular vulnerabilities
affect the Distributed Component Object Model (DCOM) interface
within the RPCSS Service. This interface handles DCOM object
activation requests that are sent from one machine to another.
An attacker who successfully exploited these vulnerabilities
could be able to run code with Local System privileges on an
affected system, or could cause the RPCSS Service to fail. The
attacker could then be able to take any action on the system,
including installing programs, viewing, changing or deleting
data, or creating new accounts with full privileges.
To exploit these vulnerabilities, an attacker could create a
program to send a malformed RPC message to a vulnerable system
targeting the RPCSS Service.
Microsoft has released a tool that can be used to scan a network
for the presence of systems which have not had the MS03-039 patch
installed. More details on this tool are available in Microsoft
Knowledge Base article 827363. This tool supersedes the one
provided in Microsoft Knowledge Base article 826369. If the tool
provided in Microsoft Knowledge Base Article 826369 is used
against a system which has installed the security patch provided
with this bulletin, the superseded tool will incorrectly report
that the system is missing the patch provided in MS03-026.
Microsoft encourages customers to run the latest version of the
tool available in Microsoft Knowledge Base article 827363 to
determine if their systems are patched.
Mitigating Factors:
====================
- Firewall best practices and standard default firewall
configurations can help protect networks from remote attacks
originating outside of the enterprise perimeter. Best practices
recommend blocking all ports that are not actually being used.
For this reason, most systems attached to the Internet should
have a minimal number of the affected ports exposed.
Risk Rating:
============
- Critical
Patch Availability:
===================
- A patch is available to fix this vulnerability. Please read

http://www.microsoft.com/technet/security/bulletin/MS03-039.asp

Thanks, I bet if another blaster type worm came around it would be alot more damaging, i'll patch up tomorrow.
What a nightmare! I just finally finished running ms03-026.exe on a batch of computers at work (was a task left undone by a now departed sysadmin). Now I've got to go do it all over again. :disgust:
MS needs to provide us with a tool to run these patches remotely. I know, there was a sample script available for running ms03-026.exe, but I haven't had time to come up to speed on the scripting language involved, and at the time it seemed easier just to log in locally at run the patch.
Are any of you administering networks of a size large enough to where it pays to automate this process somehow? If so, how are you handling these patches?
