Microsoft Security Bulletin MS13-072 - Important
Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2845537)
Published: September 10, 2013 | Updated: September 13, 2013
Version: 1.1
General Information
Executive Summary
This security update resolves 13 privately reported vulnerabilities in Microsoft Office. The most severe vulnerabilities could allow remote code execution if a specially crafted file is opened in an affected version of Microsoft Office software. An attacker who successfully exploited the most severe vulnerabilities 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.
This security update is rated Important for supported editions of Microsoft Office 2003 including (Microsoft Word 2003 and Microsoft Word Viewer), Microsoft Office 2007 (including Microsoft Word 2007 and Microsoft Office Compatibility Pack), and Microsoft Word 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by correcting the way that Microsoft Office parses specially crafted files and by correcting the manner in which the XML parser used by Word resolves external entities within a specially crafted file. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Recommendation. Customers can configure automatic updating to check online for updates from Microsoft Update by using the Microsoft Update service. Customers who have automatic updating enabled and configured to check online for updates from Microsoft Update typically will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates from Microsoft Update and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.
For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service.

Update FAQ
CVE-2013-3847, CVE-2013-3848, CVE-2013-3849, CVE-2013-3857, and CVE-2013-3858are described in multiple security bulletins. How are these bulletins related?
The Word Memory Corruption Vulnerabilities (CVE-2013-3847, CVE-2013-3848, CVE-2013-3849, CVE-2013-3857, CVE-2013-3858) affect the following products:
- Microsoft Word (MS13-072)
- Microsoft Office Services and Web Apps (MS13-067)
You need to install only the updates that correspond to the software you have installed on your system. If you need to install more than one of these updates, they can be installed in any sequence.
There are multiple update packages available for some affected software. Do I need to install all the updates listed in the Affected Software table for the software?
Yes. Customers should apply all updates offered for the software installed on their systems.
Do I need to install these security updates in a particular sequence?
No. Multiple updates for one version of Microsoft Office software can be applied in any sequence.
I have Microsoft Word 2010 installed. Why am I not being offered the 2767913 update?
The 2767913 update only applies to systems running specific configurations of Microsoft Office 2010. Other systems will not be offered the update.
I am being offered this update for software I do not have installed on my system. Why am I being offered this update?
Due to the servicing model for Microsoft Office updates, you may be offered updates for software that you do not have installed on your system. For example, you may be offered an update for a Microsoft Office product even though you do not have the specific Office product installed. For more information on this behavior and recommended actions, see Microsoft Knowledge Base Article 830335.
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 a list of Microsoft Office products an update may apply to, refer to the Microsoft Knowledge Base Article associated with the specific update.
In some cases, an update may apply to Office products that are specifically listed in the Non-Affected Software table. 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 and recommended actions, see Microsoft Knowledge Base Article 830335.
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.
What components of the Microsoft Office Compatibility Pack are updated by this bulletin?
The update included with this security bulletin applies only to the specific component within the Microsoft Office Compatibility Pack that is affected. For example, in an Excel bulletin, only the Excel compatibility pack component files are included in the update packages and not Word or PowerPoint compatibility pack component files. Word compatibility pack component files are updated in a Word bulletin and PowerPoint compatibility pack component files are updated in a PowerPoint bulletin.
How are Microsoft Office standalone programs affected by the vulnerabilities?
A Microsoft Office standalone program is affected with the same severity rating as the corresponding component in a Microsoft Office Suite. For example, a standalone installation of Microsoft Word is affected with the same severity rating as an installation of Microsoft Word that was delivered with a Microsoft Office Suite.
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.
