WMF Denial of Service Vulnerability - CVE-2007-1211:

A denial of service vulnerability exists in Windows when rendering Windows Metafile (WMF) image format files. An attacker who successfully exploited this vulnerability could cause the affected system to stop responding and possibly restart.

Mitigating Factors for WMF Denial of Service Vulnerability - CVE-2007-1211:

In a Web-based attack scenario, an attacker would have to host a Web site that contains a Web page that is used to exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's Web site. After they click the link, they would be prompted to perform several actions. An attack could only occur after they performed these actions.
The vulnerability could be exploited by an attacker who convinced a user to open a specially crafted file or to view a folder that contains the specially crafted image. There is no way for an attacker to force a user to open a specially crafted file, except potentially through previewing an e-mail message.

Workarounds for WMF Denial of Service Vulnerability - CVE-2007-1211:

Microsoft has tested the following workarounds. While these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section**.**

Read e-mail messages in plain text format if you are using Outlook 2002 Service Pack 3 or a later version, or Outlook Express 6 SP1 or a later version, to help protect yourself from the HTML e-mail attack vector.

Customers using Microsoft Outlook 2002 Service Pack 3 and Microsoft Outlook Express 6 Service Pack 1 or later versions can enable this setting and view e-mail messages that are not digitally signed or e-mail messages that are not encrypted in plain text only.

Digitally signed e-mail messages or encrypted e-mail messages are not affected by the setting and may be read in their original formats. For more information about how to enable this setting in Outlook 2002, see Microsoft Knowledge Base Article 307594.

For more information about how to enable this setting in Outlook Express 6, see Microsoft Knowledge Base Article 291387.

Impact of Workaround: E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. Additionally:
- The changes are applied to the preview pane and to open messages.
- Pictures become attachments so that they are not lost.
- Because the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.

FAQ for WMF Denial of Service Vulnerability - CVE-2007-1211:

What is the scope of the vulnerability?
This is a denial of service vulnerability. An attacker who exploited this vulnerability could cause the affected system to stop responding and automatically restart. Note that the denial of service vulnerability would not allow attackers to execute code or elevate their privileges, but it could cause the affected program to stop accepting requests.

What causes the vulnerability?
The vulnerability is caused by an attempt to read a data value that contains an invalid memory reference.

What is the Windows Metafile (WMF) image formats?
The WMF image format is a 16-bit metafile format that can contain both vector information and bitmap information. It is optimized for the Windows operating system.

For more information about image types and formats, see Microsoft Knowledge Base Article 320314. Additional information about these file formats is also available at the MSDN Library Web Site.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could cause the affected system to stop responding and possibly restart.

Who could exploit the vulnerability?
In a Web-based attack scenario, an attacker would have to host a Web site that contains a Web page that is used to attempt to exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.

How could an attacker exploit this vulnerability?
The vulnerability could be exploited on the affected systems by an attacker who persuaded a user to open a specially crafted file or to view a folder that contains the specially crafted image. There is no way for an attacker to force a user to open a specially crafted file, except potentially through previewing an email message.

What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers could be at more risk if users who do not have sufficient administrative permissions are given the ability to log on to servers and run programs or browse the Internet. However, best practices strongly discourage allowing this.

I am running Internet Explorer on Windows Server 2003. Does this mitigate this vulnerability?
Yes. By default, Internet Explorer on Windows Server 2003 runs in a restricted mode that is known as Enhanced Security Configuration. This mode sets the security level for the Internet zone to High. This is a mitigating factor for Web sites that have not been added to Internet Explorer Trusted sites zone.

What is the Internet Explorer Enhanced Security Configuration?
Internet Explorer Enhanced Security Configuration is a group of preconfigured Internet Explorer settings that reduce the likelihood of a user or of an administrator downloading and running specially crafted Web content on a server. Internet Explorer Enhanced Security Configuration reduces this risk by modifying many security-related settings. This includes the settings on the Security tab and the Advanced tab in the Internet Options dialog box. Some of the important modifications include the following:

Security level for the Internet zone is set to High. This setting disables scripts, ActiveX controls, Microsoft Java Virtual Machine (MSJVM), and file downloads.

Notes When you install these security updates, the installer checks to see if one or more of the files that are being updated on your system have previously been updated by a Microsoft hotfix.

For more information about this behavior, see Microsoft Knowledge Base Article 824994.

For more information about the Update.exe installer, visit the Microsoft TechNet Web site.

For more information about the terminology that appears in this bulletin, such as hotfix, see Microsoft Knowledge Base Article 824684.

Verifying that the Update Has Been Applied

Microsoft Baseline Security Analyzer

To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the frequently asked question, “Can I use the Microsoft Baseline Security Analyzer (MBSA) to determine whether this update is required?” in the section, Frequently Asked Questions (FAQ) Related to This Security Update, earlier in this bulletin.
File Version Verification

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
1. Click Start, and then click Search.
2. In the Search Results pane, click All files and folders under Search Companion.
3. In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
4. In the list of files, right-click a file name from the appropriate file information table, and then click Properties.
  
  Note Depending on the version of the operating system or programs installed, some of the files that are listed in the file information table may not be installed.
5. On the Version tab, determine the version of the file that is installed on your computer by comparing it to the version that is documented in the appropriate file information table.
  
  Note Attributes other than the file version may change during installation. Comparing other file attributes to the information in the file information table is not a supported method of verifying that the update has been applied. Also, in certain cases, files may be renamed during installation. If the file or version information is not present, use one of the other available methods to verify update installation.

Note When you install this security update, Windows checks to see if one or more of the files that are being updated on your system have previously been updated by a Windows hotfix. If you have previously installed a hotfix to update one of these files, the installer will apply the LDR version of this update. Otherwise, the installer will apply the GDR version of the update.

For more information about this behavior, see Microsoft Knowledge Base Article 824994.

For more information about the wusa.exe installer, see Microsoft Knowledge Base Article 934307.

For more information about the terminology that appears in this bulletin, such as hotfix, see Microsoft Knowledge Base Article 824684.

Verifying that the Update Has Been Applied

Microsoft Baseline Security Analyzer

To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the frequently asked question, “Can I use the Microsoft Baseline Security Analyzer (MBSA) to determine whether this update is required?” in the section, Frequently Asked Questions (FAQ) Related to This Security Update, earlier in this bulletin.
File Version Verification

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.
1. Click Start and then enter an update file name in Start Search.
2. When the file appears under Programs, right-click on the file name and click Properties.
3. Under the General tab, compare the file size with the file information tables provided earlier in this section.
4. You may also click on the Details tab and compare information, such as file version and date modified, with the file information tables provided earlier in this section.
5. Finally, you may also click on the Previous Versions tab and compare file information for the previous version of the file with the file information for the new, or updated, version of the file.

Office Update

Software Update Services:

By using Microsoft Software Update Services (SUS), administrators can quickly and reliably deploy the latest critical updates and security updates to Windows 2000 and Windows Server 2003-based servers, and to desktop systems that are running Windows 2000 Professional or Windows XP Professional.

For more information about how to deploy security updates by using Software Update Services, visit the Software Update Services Web site.

Windows Server Update Services:

By using Windows Server Update Services (WSUS), administrators can quickly and reliably 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 onto Windows 2000 and later operating systems.

For more information about how to deploy security updates using Windows Server Update Services, visit the Windows Server Update Services Web site.

Systems Management Server:

Microsoft Systems Management Server (SMS) delivers a highly configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and can perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. For more information about how administrators can use SMS 2003 to deploy security updates, visit the SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack to help deploy security updates. For information about SMS, visit the SMS Web site.

Note SMS uses the Microsoft Baseline Security Analyzer, the Microsoft Office Detection Tool, and the Enterprise Update Scan Tool to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to target updates to specific systems. For more information about this procedure, visit the following Web site. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
