Microsoft Security Bulletin MS16-055 - Critical

Security Update for Microsoft Graphics Component (3156754)

Published: May 10, 2016

Version: 1.0

Executive Summary

This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted document or visits a specially crafted website. 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.

This security update is rated Critical for all supported releases of Microsoft Windows. For more information, see the Affected Software section.

The security update addresses the vulnerabilities by correcting how the Windows GDI component and the Windows Imaging Component handle objects in memory.

For more information about the vulnerabilities, see the Vulnerability Information section.

For more information about this update, see Microsoft Knowledge Base Article 3156754.

Vulnerability Information

Multiple Windows Graphics Component Information Disclosure Vulnerabilities

Information disclosure vulnerabilities exist when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerabilities could obtain information to further compromise the user’s system.

There are multiple ways an attacker could exploit the vulnerabilities, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The update addresses the vulnerabilities by correcting how the Windows GDI component handle objects in memory.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

Vulnerability title CVE number Publicly disclosed Exploited
Windows Graphics Component Information Disclosure Vulnerability CVE-2016-0168 No No
Windows Graphics Component Information Disclosure Vulnerability CVE-2016-0169 No No

Mitigating Factors

Microsoft has not identified any mitigating factors for these vulnerabilities.

Workarounds

The following workarounds may be helpful in your situation:

  • 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 by using Registry Editor, follow these 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 in the Open box, and then click OK.
    2. Locate and then click the following registry subkey:
        HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\GRE_Initialize
    
    1. On the Edit menu, point to New, and then click DWORD.
    2. Type DisableMetaFiles, and then press ENTER.
    3. On the Edit menu, click Modify to modify the DisableMetaFiles registry entry.
    4. In the Value data box, type 1, and then click OK.
    5. Exit Registry Editor.
    6. Restart the computer.

Impact of workaround. Turning off metafiles processing may cause the appearance of software or system components to decrease in quality. Turning off metafiles processing may also cause the software or system components to fail completely. This has been identified to have a potential significant functionality impact and should be evaluated and tested carefully to determine its applicability.

Examples include the following:

  • You cannot print on the computer.
  • Some applications on the computer may be unable to display Clipart.
  • Some scenarios that involve OLE rendering may break.

To modify the key using a managed deployment script:

  1. Save the following to a file with a .REG extension (For example, Disable_MetaFiles.reg):

            Windows Registry Editor Version 5.00  
    
            [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\GRE_Initialize]  
            "DisableMetaFiles"=dword:00000001
    
  2. Run the registry script on the target machine with the following command from an administrator (on Vista, an elevated administrator) command prompt:

        Regedit.exe /s Disable_MetaFiles.reg
    
  3. Restart the computer

How to undo the workaround

  1. Click Start, click Run, type Regedit in the Open box, and then click OK.
  2. Locate and then click the following registry subkey:

       HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\GRE_Initialize
    
  3. On the Edit menu, click Modify to modify the DisableMetaFiles registry entry.

    1. In the Value data box, type 0, and then click OK.
    2. Exit Registry Editor.
    3. Restart the computer.

Windows Graphics Component RCE Vulnerability – CVE-2016-0170

A remote code execution vulnerability exists when the Windows GDI component fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could take 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.

There are multiple ways an attacker could exploit the vulnerability:

  • In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email or Instant Messenger message that takes users to the attacker's website, or by opening an attachment sent through email.
  • In a file sharing attack scenario, an attacker could provide a specially crafted document file that is designed to exploit the vulnerability, and then convince a user to open the document file. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in the memory.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

Vulnerability title CVE number Publicly disclosed Exploited
Windows Graphics Component RCE Vulnerability CVE-2016-0170 No No
