Where are the file information details?
Refer to the reference tables in the Security Update Deployment section for the location of the file information details.

Is this update related to Microsoft Security Advisory 2269637?
Yes, a vulnerability addressed by this update is related to the class of vulnerabilities, described in Microsoft Security Advisory 2269637, that affects how applications load external libraries. This security update addresses a particular instance of this type of vulnerability.

Why does this update address several reported security vulnerabilities?
This update contains support for several vulnerabilities because the modifications that are required to address these issues are located in related files. Instead of having to install several updates that are almost the same, customers need to install this update only.

I have PowerPoint 2010 Service Pack 1 installed. If it is not affected, why am I being offered this update?
Although the vulnerabilities described in CVE-2011-3396 and CVE-2011-3413 do not affect PowerPoint 2010 Service Pack 1, the update mechanism offers the update because it detects a lower version of the files on the system as compared to those in the update package.

I use the "Package a Presentation for CD" feature. How can I help ensure my presentations are protected from the vulnerabilities described in this bulletin?
After applying this security update to affected software, customers running supported editions of Microsoft PowerPoint 2003 and Microsoft PowerPoint 2007 can issue updated versions of their presentations created using the Package a Presentation for CD feature in PowerPoint to help ensure that the PowerPoint Viewer included in their presentations is protected from the vulnerabilities described in this bulletin.

What components of the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats are updated by this bulletin?
The update included with this security bulletin applies only to the specific component within the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats 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 areMicrosoft 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 PowerPoint is affected with the same severity rating as an installation of Microsoft PowerPoint that was delivered with a Microsoft Office Suite.

The Microsoft Office component discussed in this article is part of the Microsoft Office Suite that I have installed on my system; however, I did not choose to install this specific component. Will I be offered this update?
Yes, if the component discussed in this bulletin was delivered with the version of the Microsoft Office Suite installed on your system, the system will be offered updates for it whether the component is installed or not. The detection logic used to scan for affected systems is designed to check for updates for all components that were delivered with the particular Microsoft Office Suite and to offer the updates to a system. Users who choose not to apply an update for a component that is not installed, but is delivered with their version of the Microsoft Office Suite, will not increase the security risk of that system. On the other hand, users who do choose to install the update will not have a negative impact on the security or performance of a system.

Does the offer to update a non-vulnerable version of Microsoft Office constitute an issue in the Microsoft update mechanism?
No, the update mechanism is functioning correctly in that it detects a lower version of the files on the system than in the update package and thus, offers the update.

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 have been tested to determine which releases are affected. Other releases are past their support life cycle. For more information about the product lifecycle, visit the Microsoft Support Lifecycle Web site.

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.

PowerPoint Insecure Library Loading Vulnerability - CVE-2011-3396

A remote code execution vulnerability exists in the way that Microsoft PowerPoint handles the loading of DLL files. 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-2011-3396.

Mitigating Factors for PowerPoint Insecure Library Loading Vulnerability - CVE-2011-3396

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:

  • The file sharing protocol, Server Message Block (SMB), is often disabled on the perimeter firewall. This limits the potential attack vectors for this vulnerability.
  • For an attack to be successful, a user must visit an untrusted remote file system location or WebDAV share and open a PowerPoint file (such as a .ppt file).

Workarounds for PowerPoint Insecure Library Loading Vulnerability - CVE-2011-3396

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 loading of libraries from WebDAV and remote network shares

    Note See Microsoft Knowledge Base Article 2264107 to deploy a workaround tool that allows customers to disable the loading of libraries from remote network or WebDAV shares. This tool can be configured to disallow insecure loading on a per-application or a global system basis.

    Customers who are informed by their vendor of an application being vulnerable can use this tool to help protect against attempts to exploit this issue.

    Note See Microsoft Knowledge Base Article 2264107 to use the automated Microsoft Fix it solution to deploy the registry key to block the loading of libraries for SMB and WebDAV shares. Note that this Fix it solution does require you to install the workaround tool also described in Microsoft Knowledge Base Article 2264107 first. This Fix it solution only deploys the registry key and requires the workaround tool in order to be effective. We recommend that administrators review the KB article closely prior to deploying this Fix it solution.

  • Disable the WebClient service

    Disabling the WebClient service helps protect affected systems from attempts to exploit this vulnerability by blocking the most likely remote attack vector through the Web Distributed Authoring and Versioning (WebDAV) client service. After applying this workaround it is still possible for remote attackers who successfully exploit this vulnerability to cause the system to run programs located on the targeted user's computer or the Local Area Network (LAN), but users will be prompted for confirmation before opening arbitrary programs from the Internet.

    To disable the WebClient Service, follow these steps:

    1. Click Start, click Run, type Services.msc and then click OK.
    2. Right-click WebClient service and select Properties.
    3. Change the Startup type to Disabled. If the service is running, click Stop.
    4. Click OK and exit the management application.

    Impact of workaround. When the WebClient service is disabled, Web Distributed Authoring and Versioning (WebDAV) requests are not transmitted. In addition, any services that explicitly depend on the Web Client service will not start, and an error message will be logged in the System log. For example, WebDAV shares will be inaccessible from the client computer.

    How to undo the workaround.

    To re-enable the WebClient Service, follow these steps:

    1. Click Start, click Run, type Services.msc and then click OK.
    2. Right-click WebClient service and select Properties.
    3. Change the Startup type to Automatic. If the service is not running, click Start.
    4. Click OK and exit the management application.
  • Block TCP ports 139 and 445 at the firewall

    These ports are used to initiate a connection with the affected component. Blocking TCP ports 139 and 445 at the firewall will help protect systems that are behind that firewall from attempts to exploit this vulnerability. Microsoft recommends that you block all unsolicited inbound communication from the Internet to help prevent attacks that may use other ports. For more information about ports, see the TechNet article, TCP and UDP Port Assignments.

    Impact of workaround. Several Windows services use the affected ports. Blocking connectivity to the ports may cause various applications or services to not function. Some of the applications or services that could be impacted are listed below:

    • Applications that use SMB (CIFS)
    • Applications that use mailslots or named pipes (RPC over SMB)
    • Server (File and Print Sharing)
    • Group Policy
    • Net Logon
    • Distributed File System (DFS)
    • Terminal Server Licensing
    • Print Spooler
    • Computer Browser
    • Remote Procedure Call Locator
    • Fax Service
    • Indexing Service
    • Performance Logs and Alerts
    • Systems Management Server
    • License Logging Service

    How to undo the workaround. Unblock TCP ports 139 and 445 at the firewall. For more information about ports, see TCP and UDP Port Assignments.

FAQ for PowerPoint Insecure Library Loading Vulnerability - CVE-2011-3396

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.

What causes the vulnerability?
The vulnerability is caused when Microsoft PowerPoint improperly restricts the path used for loading external libraries.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If a user is logged on with administrative user rights, an attacker could take complete control of the affected system. 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 convince a user to open a legitimate file that is located in the same network directory as a specially crafted dynamic link library (DLL) file. Then, while opening the legitimate file, Microsoft PowerPoint could attempt to load the DLL file and execute any code it contained.

In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a legitimate file attachment to a user, and convincing the user to place the attachment into a directory containing a specially crafted DLL file and to open the legitimate file. Then, while opening the legitimate file, Microsoft PowerPoint could attempt to load the DLL file and execute any code it contained.

In a network attack scenario, an attacker could place a legitimate file and a specially crafted DLL file in a network share, a UNC, or WebDAV location and then convince the user to open the file.

What systems are primarily at risk from the vulnerability?
This vulnerability mainly affects workstations where users may be expected to open attachments from untrusted network locations. Servers could also be at risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What does the update do?
The update addresses this vulnerability by correcting the way that PowerPoint loads external libraries.

Is this vulnerability related to Microsoft Security Advisory 2269637?
Yes, this vulnerability is related to the class of vulnerabilities, described in Microsoft Security Advisory 2269637, that affects how applications load external libraries. This security update addresses a particular instance of this type of vulnerability.

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.

OfficeArt Shape RCE Vulnerability - CVE-2011-3413

A remote code execution vulnerability exists in the way that Microsoft PowerPoint handles specially crafted PowerPoint files. An attacker could exploit the vulnerability by creating a specially crafted PowerPoint file that could be included as an e-mail attachment, or hosted on a specially crafted or compromised Web site.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2011-3413.

Mitigating Factors for OfficeArt Shape RCE Vulnerability - CVE-2011-3413

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 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.
  • 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 persuade 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.
  • 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 OfficeArt Shape RCE Vulnerability - CVE-2011-3413

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:

  • Use Microsoft Office File Block policy to block the opening of Office 2003 and earlier documents from unknown or untrusted sources and locations

    Microsoft Office File Block policy can be used to block specific file format types from opening in Microsoft Word, Microsoft Excel, and Microsoft PowerPoint.

    For Microsoft Office 2007

    The following registry scripts can be saved in registry entry (.reg) files and used to set the File Block policy. For more information on how to use registry scripts, see Microsoft Knowledge Base Article 310516.

    Note In order to use 'FileOpenBlock' with Microsoft Office 2007, all of the latest security updates for Office 2007 must be applied.

    Microsoft Office Software Registry Script
    Microsoft PowerPoint 2007 Windows Registry Editor Version 5.00\ \ [HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\PowerPoint\Security\FileOpenBlock]\ \ "BinaryFiles"=dword:00000001

    How to undo the workaround.

    For Microsoft Office 2007, use the following registry scripts to undo the settings used to set the File Block policy:

    Microsoft Office Software Registry Script
    Microsoft PowerPoint 2007 Windows Registry Editor Version 5.00\ \ [HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\PowerPoint\Security\FileOpenBlock]\ \ "BinaryFiles"=dword:00000000
  • Use the Microsoft Office Isolated Conversion Environment (MOICE) when opening files from unknown or untrusted sources

    Note Modifying the Registry incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from incorrect modification of the Registry can be solved. Modify the Registry at your own risk.

    The Microsoft Office Isolated Conversion Environment (MOICE) helps protect Office 2003 installations by more securely opening Word, Excel, and PowerPoint binary format files.

    To install MOICE, you must have Office 2003 or Office 2007 installed.

    To install MOICE, you must also have the Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats. The compatibility pack is available as a free download from the Microsoft Download Center.

    MOICE requires all updates that are recommended for all Office programs. Visit Microsoft Update to install all recommended updates.

    Enable MOICE

    Note See Microsoft Knowledge Base Article 935865 to use the automated Microsoft Fix it solution to enable or disable this workaround.

    To manually enable MOICE, run the commands as specified in the following table. Running the commands will associate the Office application extensions with MOICE.

    Command to enable MOICE to be the registered handler
    For Word, run the following command from a command prompt:\ ASSOC .doc=oice.word.document
    For Excel, run the following commands from a command prompt:\ ASSOC .XLS=oice.excel.sheet\ ASSOC .XLT=oice.excel.template\ ASSOC .XLA=oice.excel.addin
    For PowerPoint, run the following commands from a command prompt:\ ASSOC .PPT=oice.powerpoint.show\ ASSOC .POT=oice.powerpoint.template\ ASSOC .PPS=oice.powerpoint.slideshow

    Note On Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, run the above commands from an elevated command prompt.

    For more information on MOICE, see Microsoft Knowledge Base Article 935865.

    Impact of workaround. Office 2003 and earlier formatted documents that are converted to the Microsoft Office 2007 Open XML format by MOICE will not retain macro functionality. Additionally, documents with passwords or that are protected with Digital Rights Management cannot be converted.

    How to undo the workaround. Run the commands to disable MOICE as specified in the table below.

    Command to disable MOICE as the registered handler
    For Word, run the following command from a command prompt:\ ASSOC .doc=Word.Document.8
    For Excel, run the following commands from a command prompt:\ ASSOC .xls=Excel.Sheet.8\ ASSOC .xlt=Excel.Template\ ASSOC .xla=Excel.Addin
    For PowerPoint, run the following commands from a command prompt:\ ASSOC .ppt=PowerPoint.Show.8\ ASSOC .PPS=oice.powerpoint.slideshow\ ASSOC .pps=PowerPoint.SlideShow.8

    Note On Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, run the above commands from an elevated command prompt.

This security update supports the following setup switches.

Supported Security Update Installation Switches

Switch Description
/? or /help Displays usage dialog.
/passive Specifies passive mode. Requires no user interaction; users see basic progress dialogs but cannot cancel.
/quiet Specifies quiet mode, or suppresses prompts, when files are being extracted.
/norestart Suppresses restarting the system if the update requires a restart.
/forcerestart Automatically restarts the system after applying the update, regardless of whether the update requires the restart.
/extract Extracts the files without installing them. You are prompted for a target folder.
/extract:<path> Overrides the install command that is defined by author. Specifies the path and name of the Setup.inf or .exe file.
/lang:<LCID> Forces the use of a specific language, when the update package supports that language.
/log:<log file> Enables logging, by both Vnox and Installer, during the update installation.

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.

    1. Click Start and then enter an update file name in the Start Search box.
    2. When the file appears under Programs, right-click the file name and click Properties.
    3. On the General tab, compare the file size with the file information tables provided in the bulletin KB article.
      Note Depending on the edition of the operating system, or the programs that are installed on your system, some of the files that are listed in the file information table may not be installed.
    4. You can also click the Details tab and compare information, such as file version and date modified, with the file information tables provided in the bulletin KB article.
      Note Attributes other than the file version may change during installation.
