Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2489293)
Published: April 12, 2011
Version: 1.0
General Information
Executive Summary
This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Office file or if a user opens a legitimate Office file that is located in the same network directory as a specially crafted library file. An attacker who successfully exploited either of these vulnerabilities could gain the same user rights as the logged on 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 all supported editions of Microsoft Office XP, Microsoft Office 2003, Microsoft Office 2007, Microsoft Office 2004 for Mac, and Microsoft Office 2008 for Mac; and Open XML File Format Converter for Mac. 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 handles graphic objects in specially crafted Office files and by correcting the manner in which Microsoft Office loads external libraries. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

Office Component Insecure Library Loading Vulnerability - CVE-2011-0107
A remote code execution vulnerability exists in the way that Microsoft Office 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-2011-0107.
Mitigating Factors for Office Component Insecure Library Loading Vulnerability - CVE-2011-0107
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:
- For an attack to be successful, a user must visit an untrusted remote file system location or WebDAV share and open an Office-related file (such as a .docx file).
- The file sharing protocol, Server Message Block (SMB), is often disabled on the perimeter firewall. This limits the potential attack vectors for this vulnerability.
- An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on 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 Office Component Insecure Library Loading Vulnerability - CVE-2011-0107
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 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:
- Click Start, click Run, type Services.msc and then click OK.
- Right-click WebClient service and select Properties.
- Change the Startup type to Disabled. If the service is running, click Stop.
- 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:
- Click Start, click Run, type Services.msc and then click OK.
- Right-click WebClient service and select Properties.
- Change the Startup type to Automatic. If the service is not running, click Start.
- 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 Office Component Insecure Library Loading Vulnerability - CVE-2011-0107
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 Office incorrectly restricts the path used for loading external libraries.
How is Microsoft Office affected by this vulnerability?
Although the known attack vectors can only leverage Microsoft Word, the vulnerable code exists in a shared component of Microsoft Office.
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 Office-related file (such as a .docx 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 Office 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 Office-related file attachment (such as a .docx file) 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 Office could attempt to load the DLL file and execute any code it contained.
In a network attack scenario, an attacker could place a legitimate Office-related file and a specially crafted DLL 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?
Systems where Microsoft Office is used, including workstations and terminal servers, are primarily at risk. Servers could be at more 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 manner in which Microsoft Office loads external libraries.
Is this vulnerability related to Microsoft Security Advisory 2269637?

Mitigating Factors for Microsoft Office Graphic Object Dereferencing Vulnerability - CVE-2011-0977
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 logged-on 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.
- 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.
- In a Web-based attack scenario, an attacker would have to host a Web site that contains a specially crafted Office file that is used to attempt to exploit this vulnerability. In addition, compromised Web sites and Web sites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. 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 that takes users to the attacker's Web site, and then convince them to open a specially crafted Office file.
Workarounds for Microsoft Office Graphic Object Dereferencing Vulnerability - CVE-2011-0977
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 in Microsoft Excel from unknown or untrusted sources and locations
The following registry scripts can be used to set the File Block policy.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.

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.
