PROBLEM: Several remote code execution vulnerabilities exist in the way
that GDI handles: 1) integer valculations; and 2) filename
parameters in EMF files. The vulnerability could allow remote
code execution if a user opens a specially crafted EMF or WMF
image file.

Microsoft Security Bulletin MS08-021 – Critical
Vulnerabilities in GDI Could Allow Remote Code Execution (948590)
Published: April 8, 2008 | Update: April 11, 2008
Version: 1.2
General Information
Executive Summary
This security update resolves two privately reported vulnerabilities in GDI.
Exploitation of either of these vulnerabilities could allow remote code execution
if a user opens a specially crafted EMF or WMF image file. An attacker who
successfully exploited these vulnerabilities could take complete control of an
affected system. An attacker could then install programs; view, change, or delete
data; or create new accounts with full user rights.
This is a critical security update for Microsoft Windows 2000 Service Pack 4, and
all supported releases of Windows XP, Windows Server 2003, Windows Vista, and
Windows Server 2008. For more information, see the subsection, Affected and
Non-Affected Software, in this section.
This security update addresses the vulnerability by modifying the way that GDI
handles integer calculations and string parameters. 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 immediately
Known Issues. Microsoft Knowledge Base Article 948590 documents the currently
known issues that customers may experience when they uninstall this security
update.

GDI Heap Overflow Vulnerability - CVE-2008-1083
A remote code execution vulnerability exists in the way that GDI handles integer
calculations. The vulnerability could allow remote code execution if a user opens
a specially crafted EMF or WMF image file. An attacker who successfully exploited
this vulnerability could take complete control of an affected system. An attacker
could then install programs; view, change, or delete data; or create new accounts.
To view this vulnerability as a standard entry in the Common Vulnerabilities and
Exposures list, see CVE-2008-1083.
GDI Stack Overflow Vulnerability - CVE-2008-1087
A remote code execution vulnerability exists in the way that GDI handles filename
parameters in EMF files. The vulnerability could allow remote code execution if a
user opens a specially crafted EMF image file. An attacker who successfully
exploited this vulnerability could take complete control of an affected system. An
attacker could then install programs; view, change, or delete data; or create new
accounts.
To view this vulnerability as a standard entry in the Common Vulnerabilities and
Exposures list, see CVE-2008-1087.
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.

MBSA 2.0.1 on a supported operating system and then scan the Windows Vista-based
computer remotely. For additional information about MBSA support for Windows
Vista, visit the MBSA Web site. See also Microsoft Knowledge Base Article 931943:
Microsoft Baseline Security Analyzer (MBSA) support for Windows Vista.
For more information about MBSA 2.0.1, see MBSA 2.0 Frequently Asked Questions.
Windows Server Update Services
By using Windows Server Update Services (WSUS), administrators can deploy the
latest critical updates and security updates for Windows 2000 operating systems
and later, Office XP and later, Exchange Server 2003, and SQL Server 2000 to
Windows 2000 and later operating systems. For more information about how to
deploy this security update using Windows Server Update Services, visit the
Windows Server Update Services Web site.

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 Vista and Windows Server 2008 Microsoft Systems Management
Server 2003 with Service Pack 3 includes support for Windows Vista manageability.
