Microsoft Security Bulletin MS08-037 – Important
Vulnerabilities in DNS Could Allow Spoofing (953230)
Published: July 8, 2008 | Updated: July 23, 2008
Version: 2.1
General Information
Executive Summary
This security update resolves two privately reported vulnerabilities in the
Windows Domain Name System (DNS) that could allow spoofing. These vulnerabilities
exist in both the DNS client and DNS server and could allow a remote attacker to
redirect network traffic intended for systems on the Internet to the attacker’s
own systems.
This security update is rated Important for all supported editions of Microsoft
Windows 2000, Windows XP, Windows Server 2003, and Windows Server 2008. For more
information, see the subsection, Affected and Non-Affected Software, in this
section.
The security update addresses the vulnerabilities by using strongly random DNS
transaction IDs, using random sockets for UDP queries, and updating the logic
used to manage the DNS cache. For more information about the vulnerability, see
the Frequently Asked Questions (FAQ) subsection for the specific vulnerability
entry under the next section, Vulnerability Information.
Recommendation. Microsoft recommends that customers apply the update at the
earliest opportunity.
Known Issues. Microsoft Knowledge Base Article 953230 documents the currently
known issues that customers may experience when they install this security update.

DNS Insufficient Socket Entropy Vulnerability - CVE-2008-1447
A spoofing vulnerability exists in Windows DNS client and Windows DNS server. This
vulnerability could allow a remote unauthenticated attacker to quickly and reliably
spoof responses and insert records into the DNS server or client cache, thereby
redirecting Internet traffic.
To view this vulnerability as a standard entry in the Common Vulnerabilities and
Exposures list, see CVE-2008-1447.
DNS Cache Poisoning Vulnerability - CVE-2008-1454
A cache poisoning vulnerability exists in Windows DNS Server. The vulnerability
could allow an unauthenticated remote attacker to send specially crafted responses
to DNS requests made by vulnerable systems, thereby poisoning the DNS cache and
redirecting Internet traffic from legitimate locations.
To view this vulnerability as a standard entry in the Common Vulnerabilities and
Exposures list, see CVE-2008-1454.
Update Information
Detection and Deployment Tools and Guidance
Manage the software and security updates you need to deploy to the servers,
desktop, and mobile systems in your organization. For more information see the
TechNet Update Management Center. The Microsoft TechNet Security Web site provides
additional information about security in Microsoft products.
Security updates are available from Microsoft Update, Windows Update, and Office
Update. Security updates are also available from the Microsoft Download Center.
You can find them most easily by doing a keyword search for "security update."
Finally, security updates can be downloaded from the Microsoft Update Catalog. The
Microsoft Update Catalog provides a searchable catalog of content made available
through Windows Update and Microsoft Update, including security updates, drivers
and service packs. By searching using the security bulletin number (such as,
“MS07-036”), you can add all of the applicable updates to your basket (including
different languages for an update), and download to the folder of your choosing.
For more information about the Microsoft Update Catalog, see the Microsoft Update
Catalog FAQ.
Detection and Deployment Guidance
Microsoft has provided detection and deployment guidance for this month’s security
updates. This guidance will also help IT professionals understand how they can use
various tools to help deploy the security update, such as Windows Update, Microsoft
Update, Office Update, the Microsoft Baseline Security Analyzer (MBSA), the Office
Detection Tool, Microsoft Systems Management Server (SMS), and the Extended Security
Update Inventory Tool. For more information, see Microsoft Knowledge Base Article
910723.
Microsoft Baseline Security Analyzer
Microsoft Baseline Security Analyzer (MBSA) allows administrators to scan local and
remote systems for missing security updates as well as common security
misconfigurations. For more information about MBSA, visit Microsoft Baseline
Security Analyzer.

For SMS 2.0 and SMS 2003, the SMS SUS Feature Pack (SUSFP), which includes
the Security Update Inventory Tool (SUIT), can be used by SMS to detect
security updates. See also Downloads for Systems Management Server 2.0.
For SMS 2003, the SMS 2003 Inventory Tool for Microsoft Updates (ITMU) can be
used by SMS to detect security updates that are offered by Microsoft Update
and that are supported by Windows Server Update Services. For more information
about the SMS 2003 ITMU, see SMS 2003 Inventory Tool for Microsoft Updates.
SMS 2003 can also use the Microsoft Office Inventory Tool to detect required
updates for Microsoft Office applications. For more information about the
Office Inventory Tool and other scanning tools, see SMS 2003 Software Update
Scanning Tools. See also Downloads for Systems Management Server 2003.
System Center Configuration Manager (SCCM) 2007 uses WSUS 3.0 for detection of
updates. For more information about SCCM 2007 Software Update Management, visit
System Center Configuration Manager 2007.
Note for Windows Server 2008 Microsoft Systems Management Server 2003 with
Service Pack 3 includes support for Windows Server 2008 manageability.
For more information about SMS, visit the SMS Web site.
For more detailed information, see Microsoft Knowledge Base Article 910723:
Summary list of monthly detection and deployment guidance articles.
Update Compatibility Evaluator and Application Compatibility Toolkit
Updates often write to the same files and registry settings required for your
applications to run. This can trigger incompatibilities and increase the time
it takes to deploy security updates. You can streamline testing and validating
Windows updates against installed applications with the Update Compatibility
Evaluator components included with Application Compatibility Toolkit 5.0.
The Application Compatibility Toolkit (ACT) contains the necessary tools and
documentation to evaluate and mitigate application compatibility issues before
deploying Microsoft Windows Vista, a Windows Update, a Microsoft Security Update,
or a new version of Windows Internet Explorer in your environment.
