Published: June 14, 2011
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Microsoft Windows Object Linking and Embedding (OLE) Automation. The vulnerability could allow remote code execution if a user visits a Web site containing a specially crafted Windows Metafile (WMF) image. In all cases, however, an attacker would have no way to force users to visit such a Web site. Instead, an attacker would have to convince users to visit a malicious Web site, typically by getting them to click a link in an e-mail message or Instant Messenger request.
This security update is rated Critical for all supported versions of Microsoft Windows. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerability by correcting the manner in which OLE Automation parses WMF files.

OLE Automation Underflow Vulnerability - CVE-2011-0658
A remote code execution vulnerability exists in Object Linking and Embedding (OLE) Automation. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2011-0658.
Mitigating Factors for OLE Automation Underflow Vulnerability - CVE-2011-0658
Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:
- In a Web-based attack scenario, an attacker could host a Web site that contains a Web page that is used to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker’s Web site.
- An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
- By default, Internet Explorer on Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2 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. See the FAQ subsection of this vulnerability section for more information about Internet Explorer Enhanced Security Configuration.
- The vulnerability cannot be exploited automatically through e-mail. For an attack to be successful a user must open an attachment that is sent in an e-mail message.
Workarounds for OLE Automation Underflow Vulnerability - CVE-2011-0658
Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:
Restrict access to VBScript.dll
To restrict access to VBScript.dll, run the following command from a command prompt:
For Windows XP (32-bit systems):
cacls %windir%\system32\vbscript.dll /E /P everyone:NFor Windows XP (64-bit systems):
cacls %windir%\syswow64\vbscript.dll /E /P everyone:NFor Windows Vista and newer (32-bit systems):
takeown /f %windir%\system32\vbscript.dllcacls %windir%\system32\vbscript.dll /E /P everyone:NFor Windows Vista and newer (64-bit systems):
takeown /f %windir%\syswow64\vbscript.dllcacls %windir%\syswow64\vbscript.dll /E /P everyone:NImpact of workaround. Web pages and other applications that require VBScript may not display properly.
How to undo the workaround.
To undo the workaround, run the following command from a command prompt:
For Windows XP (32-bit systems):
cacls %windir%\system32\vbscript.dll /E /R everyoneFor Windows XP (64-bit systems):
cacls %windir%\syswow64\vbscript.dll /E /R everyoneFor Windows Vista and newer (32-bit systems):
cacls %windir%\system32\vbscript.dll /E /R everyoneFor Windows Vista and newer (64-bit systems):
cacls %windir%\syswow64\vbscript.dll /E /R everyoneSet Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones
You can help protect against exploitation of this vulnerability by changing your settings for the Internet security zone to block ActiveX controls and Active Scripting. You can do this by setting your browser security to High.
To raise the browsing security level in Internet Explorer, perform the following steps:
- On the Internet Explorer Tools menu, click Internet Options.
- In the Internet Options dialog box, click the Security tab, and then click the Internet icon.
- Under Security level for this zone, move the slider to High. This sets the security level for all Web sites you visit to High.
Note If no slider is visible, click Default Level, and then move the slider to High.
Note Setting the level to High may cause some Web sites to work incorrectly. If you have difficulty using a Web site after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly even with the security setting set to High.
Impact of workaround. There are side effects to blocking ActiveX Controls and Active Scripting. Many Web sites that are on the Internet or on an intranet use ActiveX or Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use ActiveX Controls to provide menus, ordering forms, or even account statements. Blocking ActiveX Controls or Active Scripting is a global setting that affects all Internet and intranet sites. If you do not want to block ActiveX Controls or Active Scripting for such sites, use the steps outlined in "Add sites that you trust to the Internet Explorer Trusted sites zone".
Add sites that you trust to the Internet Explorer Trusted sites zone
After you set Internet Explorer to block ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted Web sites exactly as you do today, while helping to protect yourself from this attack on untrusted sites. We recommend that you add only sites that you trust to the Trusted sites zone.
To do this, perform the following steps:
- In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
- In the Select a Web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
- If you want to add sites that do not require an encrypted channel, click to clear the Require server verification (https:) for all sites in this zone check box.
- In the Add this Web site to the zone box, type the URL of a site that you trust, and then click Add.
- Repeat these steps for each site that you want to add to the zone.
- Click OK two times to accept the changes and return to Internet Explorer.
Note Add any sites that you trust not to take malicious action on your system. Two in particular that you may want to add are *.windowsupdate.microsoft.com and *.update.microsoft.com. These are the sites that will host the update, and it requires an ActiveX Control to install the update.
Configure Internet Explorer to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone
You can help protect against exploitation of this vulnerability by changing your settings to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone. To do this, perform the following steps:
- In Internet Explorer, click Internet Options on the Tools menu.
- Click the Security tab.
- Click Internet, and then click Custom Level.
- Under Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.
- Click Local intranet, and then click Custom Level.
- Under Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.
- Click OK two times to return to Internet Explorer.
Note Disabling Active Scripting in the Internet and Local intranet security zones may cause some Web sites to work incorrectly. If you have difficulty using a Web site after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly.
Impact of workaround. There are side effects to prompting before running Active Scripting. Many Web sites that are on the Internet or on an intranet use Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use Active Scripting to provide menus, ordering forms, or even account statements. Prompting before running Active Scripting is a global setting that affects all Internet and intranet sites. You will be prompted frequently when you enable this workaround. For each prompt, if you feel you trust the site that you are visiting, click Yes to run Active Scripting. If you do not want to be prompted for all these sites, use the steps outlined in "Add sites that you trust to the Internet Explorer Trusted sites zone".
Add sites that you trust to the Internet Explorer Trusted sites zone
After you set Internet Explorer to require a prompt before it runs ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted Web sites exactly as you do today, while helping to protect you from this attack on untrusted sites. We recommend that you add only sites that you trust to the Trusted sites zone.
To do this, perform the following steps:
- In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
- In the Select a Web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
- If you want to add sites that do not require an encrypted channel, click to clear the Require server verification (https:) for all sites in this zone check box.
- In the Add this Web site to the zone box, type the URL of a site that you trust, and then click Add.
- Repeat these steps for each site that you want to add to the zone.
- Click OK two times to accept the changes and return to Internet Explorer.
Note Add any sites that you trust not to take malicious action on your system. Two in particular that you may want to add are *.windowsupdate.microsoft.com and *.update.microsoft.com. These are the sites that will host the update, and it requires an ActiveX Control to install the update.
FAQ for OLE Automation Underflow Vulnerability - CVE-2011-0658
What is the scope of the vulnerability?
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
What causes the vulnerability?
The vulnerability is caused by the way that OLE Automation parses a specially crafted WMF file.
What is OLE Automation?
Object Linking and Embedding (OLE) Automation is a Windows protocol that allows an application to share data with or to control another application. OLE Automation is an industry standard that applications use to expose their OLE objects to development tools, macro languages, and other containers that support OLE Automation.
What is the Windows Metafile (WMF) image format?
The Windows Metafile (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.
What might an attacker use the vulnerability to do?
If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
How could an attacker exploit the vulnerability?
This vulnerability requires that a user view a specially crafted WMF image file. An attacker could host a specially crafted Web site that is designed to exploit this vulnerability through Internet Explorer and then persuade a user to view the Web site. This can also include Web sites that accept or host user-provided content or advertisements, and compromised Web sites. These Web sites could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit such Web sites. Instead, an attacker would have to convince users to visit a Web site, typically by getting them to click a link in an e-mail message or in an Instant Messenger request that takes users to the attacker's Web 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.
What systems are primarily at risk from the vulnerability?
Workstations and terminal servers are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.
I am running Internet Explorer for Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2. Does this mitigate this vulnerability?
Yes. By default, Internet Explorer on Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2 runs in a restricted mode that is known as Enhanced Security Configuration. Enhanced Security Configuration is a group of preconfigured settings in Internet Explorer that can reduce the likelihood of a user or administrator downloading and running specially crafted Web content on a server. This is a mitigating factor for Web sites that you have not added to the Internet Explorer Trusted sites zone.
What does the update do?
This security update addresses the vulnerability by correcting the manner in which OLE Automation parses WMF files.
When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.
When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security bulletin was originally issued.

Deployment Information
Installing the Update
When you install this security update, the installer checks whether one or more of the files that are being updated on your system have previously been updated by a Microsoft hotfix.
If you have previously installed a hotfix to update one of these files, the installer copies the RTMQFE, SP1QFE, or SP2QFE files to your system. Otherwise, the installer copies the RTMGDR, SP1GDR, or SP2GDR files to your system. Security updates may not contain all variations of these files. For more information about this behavior, see Microsoft Knowledge Base Article 824994.
For more information about the installer, see Microsoft Knowledge Base Article 832475.
For more information about the terminology that appears in this bulletin, such as hotfix, see Microsoft Knowledge Base Article 824684.
This security update supports the following setup switches.
| Switch | Description |
|---|---|
| /help | Displays the command-line options. |
| Setup Modes | |
| /passive | Unattended Setup mode. No user interaction is required, but installation status is displayed. If a restart is required at the end of Setup, a dialog box will be presented to the user with a timer warning that the computer will restart in 30 seconds. |
| /quiet | Quiet mode. This is the same as unattended mode, but no status or error messages are displayed. |
| Restart Options | |
| /norestart | Does not restart when installation has completed. |
| /forcerestart | Restarts the computer after installation and force other applications to close at shutdown without saving open files first. |
| /warnrestart[:x] | Presents a dialog box with a timer warning the user that the computer will restart in x seconds. (The default setting is 30 seconds.) Intended for use with the /quiet switch or the /passive switch. |
| /promptrestart | Displays a dialog box prompting the local user to allow a restart. |
| Special Options | |
| /overwriteoem | Overwrites OEM files without prompting. |
| /nobackup | Does not back up files needed for uninstall. |
| /forceappsclose | Forces other programs to close when the computer shuts down. |
| /log:path | Allows the redirection of installation log files. |
| /integrate:path | Integrates the update into the Windows source files. These files are located at the path that is specified in the switch. |
| /extract[:path] | Extracts files without starting the Setup program. |
| /ER | Enables extended error reporting. |
| /verbose | Enables verbose logging. During installation, creates %Windir%\CabBuild.log. This log details the files that are copied. Using this switch may cause the installation to proceed more slowly. |
Note You can combine these switches into one command. For backward compatibility, the security update also supports many of the setup switches that the earlier version of the Setup program uses. For more information about the supported installation switches, see Microsoft Knowledge Base Article 262841.
