GDI+ Integer Overflow Vulnerability - CVE-2011-0041

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 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 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-2011-0041.
	
Mitigating Factors for GDI+ Integer Overflow Vulnerability - CVE-2011-0041

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.

Workarounds for GDI+ Integer Overflow Vulnerability - CVE-2011-0041

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:
•	

Disable metafile processing

Customers who have applied MS07-017 or customers using Windows Vista or Windows Server 2008 can disable metafile processing by modifying the registry. This setting will help protect the affected system from attempts to exploit this vulnerability.

To modify the key, perform the following steps:

Note Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe.

1.
	

Click Start, click Run, type Regedit, and then click OK.

2.
	

Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionGRE_Initialize

3.
	

On the Edit menu, select New, and then click DWORD.

4.
	

Type DisableMetaFiles, and then press ENTER.

5.
	

On the Edit menu, click Modify to modify the DisableMetaFiles registry entry.

6.
	

In the Value data box, type 1, and then click OK.

7.
	

Exit Registry Editor.

8.
	

Restart the computer.

To disable metafile processing using a managed deployment script, perform the following steps:

1.
	

Save the following to a file with a .REG extension (e.g. Disable_MetaFiles.reg):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionGRE_Initialize]
"DisableMetaFiles"=dword:00000001

2.
	

Run the above registry script on the target machine with the following command from an administrator command prompt:
Regedit.exe /s Disable_MetaFiles.reg

3.
	

Restart the computer.

Impact of workaround. Turning off processing of metafiles may cause the performance of software or system components to decrease in functionality. Turning off processing of metafiles may also cause the software or system components to fail completely. Evaluate the applicability of this workaround. Examples of adverse results include the following:
•	

You cannot print on the computer.
•	

Some applications on the computer may be unable to display Clipart.
•	

Some applications that involve OLE rendering may break, especially when the object server is not active.

For more information on this setting, read Microsoft Knowledge Base Article 941835.

How to undo the workaround. Perform the following steps:

1.
	

Click Start, click Run, type Regedit, and then click OK.

2.

FAQ for GDI+ Integer Overflow Vulnerability - CVE-2011-0041

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. 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.

What causes the vulnerability? 
The vulnerability is caused by a memory corruption when GDI+ improperly processes a specially crafted EMF image file.

What is GDI+? 
GDI+ is a graphics device interface that provides two-dimensional vector graphics, imaging, and typography to applications and programmers.

What is the Enhanced Metafile (EMF) image format? 
EMF is a 32-bit format that can contain both vector information and bitmap information. This format is an improvement over the Windows Metafile Format (WMF) and contains extended features.

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 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.

How could an attacker exploit the vulnerability? 
An attacker could host a specially crafted Web site that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the Web site. This can also include compromised Web sites and Web sites that accept or host user-provided content or advertisements. 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 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 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.

In an e-mail attack scenario, an attacker could exploit the vulnerability by sending Outlook users a specially crafted e-mail, or by sending a specially-crafted Office Document to the user and by convincing the user to open the file or read the message.

Attackers could also exploit this vulnerability by hosting a malicious image on a network share and then convincing a user to browse to the folder in Windows Explorer.

What systems are primarily at risk from the vulnerability? 
This vulnerability requires that a user is logged on and reading e-mail messages, visiting Web sites, or opening files from a network share for any malicious action to occur. Therefore, any systems where e-mail messages are read, where Internet Explorer is used frequently, or where users have network share access, such as workstations or terminal servers, are at the most risk from this vulnerability. Systems that are not typically used to visit Web sites, such as most server systems, are at a reduced risk.

What does the update do? 
The update removes the vulnerability by modifying the way that GDI+ handles integer calculations when processing EMF 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 and had not seen any examples of proof of concept code published when this security bulletin was originally issued.

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.

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.

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.

Verifying That the Update Has Been Applied
•

File Version Verification

Because there are several versions and editions of Microsoft Windows, the following steps may be different on your system. 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 system 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.
