Frequently Asked Questions (FAQ) Related to This Security Update
Why was this bulletin revised on May 19, 2010?
Microsoft revised this bulletin to more clearly state that the updates for Microsoft Office apply to all supported Microsoft Office suites and other Microsoft Office software that contain a vulnerable version of VBE6.dll. This includes, but is not limited to, supported versions of Microsoft Office Visio and Microsoft Office Project. This also includes Office software that includes VBE6.dll but does not access the vulnerable code such as supported versions of Microsoft Office Outlook and Microsoft Office OneNote.
This is a bulletin-only change. There were no changes to the detection logic or the update files. Customers who have already successfully updated their systems, including customers with automatic updating enabled, do not need to take any action. Customers who have not installed this update previously may need to reassess whether their systems require this update based on the Affected Software table as revised and information provided in this Update FAQ.
The update is to a shared component used by Microsoft Office. Will the update be offered to Microsoft Office software that includes the shared component, even if the software does not access the vulnerable code?
Yes, the update will be offered to systems where the vulnerable shared Office component is detected. This is true even for cases where the Office software includes VBE6.dll but does not access the vulnerable code. Consult the following table for examples of Office software that this update applies to.
| Microsoft Office | Is VBE6.dll included with this software? | Does the software access the vulnerable code? |
|---|---|---|
| Microsoft Office XP, Microsoft Office 2003, 2007 Microsoft Office System | Yes | Yes, components such as Word, Excel, and PowerPoint |
| Microsoft Office OneNote 2003, Microsoft Office OneNote 2007 | Yes | No |
| Microsoft Office Outlook 2003, Microsoft Office Outlook 2007 | Yes | No |
| Microsoft Office Project 2002, Microsoft Office Project 2003, Microsoft Office Project 2007 | Yes | Yes |
| Microsoft Office Visio 2002, Microsoft Office Visio 2003, Microsoft Office Visio 2007 | Yes | Yes |
Note Use this table as a guideline only. It includes a sample of the most commonly asked-about software.
In cases where the update is offered, Microsoft recommends that customers install the update regardless of whether or not the software accesses the vulnerable code. Installing the update will help to ensure customers are running the most up-to-date version of the VBE6.dll used by Microsoft Office software.
Does the offer to update a non-vulnerable version of software 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.
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.
I have applied the required Microsoft security updates, but I still have an affected version of the Visual Basic for Applications runtime (VBE6.dll) on my system. How do I update this DLL?
There are cases where your system might still have an affected version of VBE6.dll even after you have installed the required security updates for Microsoft Office and the update for Microsoft Visual Basic for Applications listed in this bulletin.
If VBE6.dll was installed on your system by a supported version of Microsoft Office, then applying the security update for the affected version of Microsoft Office will replace VBE6.dll with the updated version that addresses the vulnerability described in this bulletin. However, if VBE6.dll was installed on your system by a third-party application, you may have to install an update for that program.
To update VBE6.dll for third-party applications there are two possible scenarios depending on the third-party application's implementation of VBA. If you know that the third-party application is compliant to the recommended best practices for using a shared component as a side-by-side assembly, then applying the Microsoft Visual Basic for Applications (KB974945) update will replace VBE6.dll in the shared location with the updated version that addresses the vulnerability described in this bulletin.
On the other hand, if the third-party application does not place VBE6.dll in the shared location as per recommended best practices, then you should contact the third-party application developer and ask them to provide you with an updated version of their application that contains a newer version of the VBE6.dll that addresses the vulnerability described in this bulletin. Note that not every third-party application that installs VBE6.dll is vulnerable to the vulnerability described in this bulletin because the application might not use VBE6.dll to search for ActiveX controls in a way that is exploitable. However, only the developer of that application can make that determination.
This security update only applies to Microsoft software. How can I detect if third-party applications have deployed an affected version of the Visual Basic for Applications runtime (VBE6.dll) on my system?
Third-party applications that support VBA could deploy VBE6.dll in a location that is not updated by this security update. In the case that you do have a third-party application that has shipped with its own copy of VBE6.dll, to help ensure that your system is fully protected from the vulnerability described in this bulletin, you should contact the developer or vendor responsible for support for the third-party application directly.
For details on how to scan for copies of VBE6.dll on your system, see Microsoft Knowledge Base Article 978213. Scanning for all copies of VBE6.dll on your system can assist in identifying potentially vulnerable copies that may have been installed by third-party applications.
I am a third-party application developer and I use Microsoft Visual Basic for Applications runtime in my application. Is my application vulnerable and how do I update it?
Developers who redistribute the Microsoft Visual Basic for Applications runtime VBE6.dll should ensure that they update the version of the Microsoft Visual Basic for Applications runtime installed with their application by downloading an updated version of the Microsoft Visual Basic for Applications SDK from the Summit Software Company. For more information on best practices on redistributed component use, please see Microsoft Knowledge Base Article 835322 and the MSDN article, Isolated Applications and Side-by-side Assemblies.
I am an ISV. Where is the update for Microsoft Visual Basic for Applications SDK?
The update is available from the Summit Software Company. Summit Software Company is a global supplier of application customization software products and integration support services to independent software vendors (ISVs) and corporate developers. In June 1996, Summit Software entered into an agreement with Microsoft to sell Microsoft Visual Basic for Applications and related value-added technology and services. Summit continues to sell and support Microsoft VBA.
Why is this update Critical for Microsoft Visual Basic for Applications but only Important for Microsoft Office?
Microsoft Office XP and later versions have a built-in feature that prompts a user to Open, Save, or Cancel before opening a document. This mitigating factor reduces the vulnerability from Critical to Important because the vulnerability requires more than a single user action to complete the exploit.
I use Microsoft Office 2007 Service Pack 1. Are any additional security features included in this update?
Yes, as part of the servicing model for Microsoft Office 2007, when users of Microsoft Office 2007 Service Pack 1 install this update, their systems will be upgraded to security functionality that was initially released with Microsoft Office 2007 Service Pack 2. All updates released after April 24, 2009 for Microsoft Office 2007 will include these security features, which were introduced in Microsoft Office 2007 Service Pack 2. We have thoroughly tested this update, but as with all updates, we recommend that users perform testing appropriate to the environment and configuration of their systems.
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.

VBE6.dll Stack Memory Corruption Vulnerability - CVE-2010-0815
A remote code execution vulnerability exists in the way that Microsoft Visual Basic for Applications searches for ActiveX controls. This vulnerability could allow remote code execution if a host application opens and passes a specially crafted file to the Visual Basic for Applications runtime. If a 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.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-0815.
Mitigating Factors for VBE6.dll Stack Memory Corruption Vulnerability - CVE-2010-0815
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:
- By default, the 2007 Microsoft Office System prompts a user with a security warning before activating an embedded ActiveX control in an Office document. Users who choose to not enable the control are protected by this default setting. For more information, see the Microsoft Office Online article, Enable or disable ActiveX controls in Office documents.
- 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 convince 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, and then convince them to open the specially crafted Office file.
- 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 VBE6.dll Stack Memory Corruption Vulnerability - CVE-2010-0815
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 ActiveX controls in the 2007 Microsoft Office System
You can disable ActiveX controls in the 2007 Microsoft Office System using the TrustCenter. Refer to the instructions for how to "Disable all controls without notification" in the Microsoft Office Online article, Enable or disable ActiveX controls in Office documents.
Impact of workaround. Embedded ActiveX controls (such as macros) will not run in Office documents.

FAQ for VBE6.dll Stack Memory Corruption Vulnerability - CVE-2010-0815
What is the scope of the vulnerability?
This is a remote code execution vulnerability in Microsoft Visual Basic for Applications (VBA). 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.
What causes the vulnerability?
The vulnerability is caused by the way that Visual Basic for Applications searches for ActiveX controls in a document that supports VBA. As a result, it is possible for a host application, such as Microsoft Office or a third-party application developed for Visual Basic programmability, to pass a specially crafted document with embedded ActiveX controls to the VBA runtime creating a condition that could allow arbitrary code to be run.
What is Visual Basic for Applications (VBA)?
Microsoft VBA is a development technology for developing client desktop packaged applications and integrating them with existing data and systems. Microsoft VBA is based on the Microsoft Visual Basic development system. Microsoft Office products include VBA and make use of VBA to perform certain functions. VBA can also be used to build customized applications based around an existing host application.
What might an attacker use the vulnerability to do?
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?
In order for an attack to be successful, a user would have to open a specially crafted document that supports VBA. This document could be any type of document that supports VBA, such as a Word document, Excel spreadsheet, or PowerPoint presentation.
In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially-crafted Office file to the user and by convincing the user to open the file.
In a Web-based attack scenario, an attacker would have to host a Web site that contains a document that supports VBA such as an 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 a specially crafted Web site.
