[1]Applies to Windows XP Service Pack 3 and Windows XP Professional x64 Edition Service Pack 2.

[2]Not a supported configuration for Microsoft Office or Microsoft Lync. It should be a priority for customers who have older releases of the software to migrate to supported releases to prevent potential exposure to vulnerabilities. To determine the support lifecycle for your software release, see Select a Product for Lifecycle Information.

I am being offered this update for software that is not specifically listed in the Affected Software table. Why am I being offered this update?
When updates address vulnerable code that exists in a component that is shared between multiple Microsoft Office products or shared between multiple versions of the same Microsoft Office product, the update is considered to be applicable to all supported products and versions that contain the vulnerable component.

For example, when an update applies to Microsoft Office 2007 products, only Microsoft Office 2007 may be specifically listed in the Affected Software table. However, the update could apply to Microsoft Word 2007, Microsoft Excel 2007, Microsoft Visio 2007, Microsoft Compatibility Pack, Microsoft Excel Viewer, or any other Microsoft Office 2007 product that is not specifically listed in the Affected Software table.

For example, when an update applies to Microsoft Office 2010 products, only Microsoft Office 2010 may be specifically listed in the Affected Software table. However, the update could apply to Microsoft Word 2010, Microsoft Excel 2010, Microsoft Visio 2010, Microsoft Visio Viewer, or any other Microsoft Office 2010 product that is not specifically listed in the Affected Software table.

For more information on this behavior and recommended actions, see Microsoft Knowledge Base Article 830335. For a list of Microsoft Office products an update may apply to, refer to the Microsoft Knowledge Base Article associated with the specific update.

I am being offered this update for software that is not vulnerable. Why am I being offered this update?
In some cases, an update may apply to Microsoft Office products that are specifically listed in the Non-Affected Software table or that are otherwise listed in the Affected Software table with "Not applicable" for security impact. For example, you may be offered a Microsoft Office security update even though this security bulletin indicates that the Office products or the version of the Office products that you do have installed are not affected. For more information on this behavior, see Microsoft Knowledge Base Article 830335.

I do not have Microsoft Lync 2013 software installed. Why am I being offered an update for Microsoft Lync 2013?
You may be offered an update for Microsoft Lync 2013 even though you do not have the affected software installed, if you have Microsoft Office software that contains the vulnerable shared component of Microsoft Office 2013 and Microsoft Lync 2013. Note that because the software does not access the vulnerable code, the software is not affected by the vulnerability. However, since the vulnerable code is present, this update will be offered.

Does the offer to update a non-vulnerable version of Microsoft Office software constitute an issue in the servicing model for Microsoft Office updates?
No. The servicing model is based on how the update applies to shared components of Microsoft Office software. Some of the products offered an update may not access the vulnerable code, and thus the software is not affected by the vulnerability. However, the update mechanism is functioning correctly in that it detects a product version for applicable software on the system that is within the range of product versions that the update applies to, and thus offers the update. This helps to maintain consistency for shared files across Office products.

Why is the Lync 2010 Attendee (user level install) update only available from the Microsoft Download Center?
Microsoft is releasing the update for Lync 2010 Attendee (user level install) to the Microsoft Download Center only. Because the user level installation of Lync 2010 Attendee is handled through a Lync session, distribution methods such as automatic updating are not appropriate for this type of installation scenario.

I am using an older release of the software discussed in this security bulletin. What should I do?
The affected software listed in this bulletin has been tested to determine which releases are affected. Other releases are past their support life cycle. For more information about the product lifecycle, see the Microsoft Support Lifecycle website.

It should be a priority for customers who have older releases of the software to migrate to supported releases to prevent potential exposure to vulnerabilities. To determine the support lifecycle for your software release, see Select a Product for Lifecycle Information. For more information about service packs for these software releases, see Service Pack Lifecycle Support Policy.

Customers who require custom support for older software must contact their Microsoft account team representative, their Technical Account Manager, or the appropriate Microsoft partner representative for custom support options. Customers without an Alliance, Premier, or Authorized Contract can contact their local Microsoft sales office. For contact information, see the Microsoft Worldwide Information website, select the country in the Contact Information list, and then click Go to see a list of telephone numbers. When you call, ask to speak with the local Premier Support sales manager. For more information, see the Microsoft Support Lifecycle Policy FAQ.

Microsoft Graphics Component Memory Corruption Vulnerability - CVE-2013-3906

A remote code execution vulnerability exists in the way that affected Windows components and other affected software handle specially crafted TIFF files. The vulnerability could allow remote code execution if a user views TIFF files in shared content. 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 administrative rights.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2013-3906.

Mitigating Factors

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:

  • An attacker who successfully exploited this vulnerability could gain the same user rights as the current 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

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 the TIFF codec

    Note See Microsoft Knowledge Base Article 2908005 to use the automated Microsoft Fix it solution to enable or disable this workaround.

    Note This workaround is not applicable to Windows 8, Windows 8.1, Windows Server 2012, Windows Server 2012 R2, Windows RT, and Windows RT 8.1.

    You can prevent TIFF files from being displayed by modifying the registry to control the parsing of the TIFF codec. By changing the registry entries, you can control which images are parsed and rendered and which images are rejected in GDI+. For example, you can select to parse and render Joint Photographic Experts Group (JPEG) images, but block Tagged Image File Format (TIFF) images.

    Warning: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

    Note After you change a registry entry, you must restart the application that uses the codec.

    To disable the TIFF codec:

    1. To add a registry entry, create one of the following registry subkeys for the appropriate Windows platform:

      For 32-bit systems:
      HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Gdiplus

      For 32-bit applications on 64-bit systems:
      HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Gdiplus

      For 64-bit systems:
      HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Gdiplus

    2. Create a DWORD value for the TIFF code by creating a registry entry (DWORD value) under the registry subkey you created in step 1:

      DisableTIFFCodec

    3. To disable the TIFF codec, set value of the DisableTIFFCodec registry entry to 1.

    Impact of Workaround. You will not be able to view TIFF files using any of the affected products.

    How to undo the workaround

    To re-enable the TIFF codec, set the value of the DisableTIFFCodec registry entry to 0.

  • Disable data collaboration in Lync

    Enterprise users who manage directly a Lync server can prevent PowerPoint files (which may be used as an attack vector to send specially crafted TIFF files) from being shared through Lync by using the Lync Server Control Panel to modify the Lync conferencing policy for data collaboration.

    For Lync 2010 and Lync 2013:

    1. Open the Lync Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.
    2. In the left navigation bar, click Conferencing and then click Conferencing Policy.
    3. In the list of conferencing policies, click Data collaboration, click Edit, and then click Show details.
    4. To prevent data collaboration, in Edit Conferencing Policy, click None. The default setting is Enable data collaboration.
    5. Click Commit.

    Impact of Workaround. Users will not be able to share and collaborate on PowerPoint files, polls, and Whiteboard during Lync meetings.

    How to undo the workaround

FAQ

What is the scope of the vulnerability?
This is a remote code execution vulnerability.

What causes the vulnerability?
The vulnerability is caused when Microsoft Windows, Microsoft Office, or Microsoft Lync fails to properly handle specially crafted TIFF files. System memory may be corrupted in such a way that an attacker could execute arbitrary code.

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

What is a TIFF file?
A TIFF (tagged image file format) file allows information to be embedded in the image file, such as the compression scheme, color mode, and size.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could cause arbitrary code to run with the privileges of the user who opens a specially crafted file or browses a website that contains specially crafted content. If the user is logged on with administrative user rights, 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.

How could an attacker exploit the vulnerability?
There are multiple means that could allow an attacker to exploit this vulnerability.

In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit this 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 message or in an 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 this vulnerability, and then convince a user to open the document file.

In an email attack scenario, an attacker could exploit the vulnerability by sending specially crafted Office data in the contents of an email message. The vulnerability could be exploited when a user opens or previews the specially crafted email message in Outlook while using Microsoft Word as the email reader. Note that by default, Microsoft Word is not the email reader in Outlook 2003. An attacker could also exploit the vulnerability by sending a specially crafted Office file to the user, and then convincing the user to open the file with an affected version of Microsoft Office software.

In a local attack scenario, an attacker could also exploit this vulnerability by running a specially crafted application to take complete control over the affected system. However, the attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability in this scenario.

What systems are primarily at risk from the vulnerability?
Workstations and terminal servers running affected software are primarily at risk.

Does EMET help mitigate attacks that could attempt to exploit this vulnerability?
Yes. The Enhanced Mitigation Experience Toolkit (EMET) enables users to manage security mitigation technologies that help make it more difficult for attackers to exploit vulnerabilities in a given piece of software. EMET helps to mitigate this vulnerability in affected software on systems where EMET is installed and configured to work with the affected software.

For more information about EMET, see The Enhanced Mitigation Experience Toolkit.

What does the update do?
The update addresses the vulnerability by correcting the way the affected software handles TIFF files.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
Yes. This vulnerability has been publicly disclosed. It has been assigned Common Vulnerability and Exposure number CVE-2013-3906. This vulnerability was first described in Microsoft Security Advisory 2896666.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
Yes. Microsoft is aware of targeted attacks that attempt to exploit this vulnerability in Microsoft Office products.
