Advisory FAQ

Does this advisory apply to Server Core installations?
This advisory does not apply to supported editions of Windows Server 2008, Windows Server 2008 R2, or Windows Server 2012 as indicated in the Non-Affected Software table, when installed using the Server Core installation option. For more information on this installation option, see the TechNet articles, Managing a Server Core Installation: Overview, Servicing a Server Core Installation, and Server Core and Full Server Integration Overview.

Does this update replace the Cumulative Security Update of ActiveX Kill Bits (2618451)?
No, for the purpose of automatic updating, this update does not replace the Cumulative Security Update of ActiveX Kill Bits (2618451) that is described in Microsoft Security Bulletin MS11-090. Automatic updating may still offer the MS11-090 update to customers regardless of whether or not they installed this update (2820197). However, customers who install this update (2820197) do not need to install the MS11-090 update to be protected with all the kill bits set in MS11-090.

What kill bits does this Update Rollup of ActiveX Kill Bits contain?
This Update Rollup of ActiveX Kill Bits contains new kill bits and all kill bits previously released in MS08-023, Security Update of ActiveX Kill Bits;MS08-032, Cumulative Security Update of ActiveX Kill Bits; MS09-032, Cumulative Security Update of ActiveX Kill Bits; MS09-055, Cumulative Security Update of ActiveX Kill Bits;MS10-008, Cumulative Security Update of ActiveX Kill Bits; MS10-034, Cumulative Security Update of ActiveX Kill Bits;MS11-027, Cumulative Security Update of ActiveX Kill Bits; MS11-090, Cumulative Security Update of ActiveX Kill Bits; and advisories titled Update Rollup for ActiveX Kill Bits, Microsoft Security Advisory 953839, Microsoft Security Advisory 956391, Microsoft Security Advisory 960715, Microsoft Security Advisory 969898, Microsoft Security Advisory 2562937, Microsoft Security Advisory 2647518, Microsoft Security Advisory 2695962, and Microsoft Security Advisory 2736233.

Why is Microsoft releasing this Update Rollup for ActiveX Kill Bits with a security advisory when previous kill bit updates were released with a security bulletin?
Microsoft is releasing this Update Rollup for ActiveX Kill Bits with an advisory because the new kill bits do not affect Microsoft software.

What is a kill bit?
A security feature in Microsoft Internet Explorer makes it possible to prevent an ActiveX control from ever being loaded by the Internet Explorer HTML-rendering engine. This is done by making a registry setting and is referred to as setting the kill bit. After the kill bit is set, the control can never be loaded, even when it is fully installed. Setting the kill bit makes sure that even if a vulnerable component is introduced or is re-introduced to a system, it remains inert and harmless.

For more information on kill bits, see Microsoft Knowledge Base Article 240797: How to stop an ActiveX control from running in Internet Explorer.

Why does this update not contain any binary files?
This update only makes changes to the registry to disable the controls from instantiating in Internet Explorer.

Should I install this update if I do not have the affected component installed or use the affected platform?
Yes. Installing this update will block the vulnerable controls from running in Internet Explorer.

Does this update contain any kill bits that are not Microsoft-specific?
Yes. Microsoft has been requested by organizations to set the kill bit for controls that the organizations own and have found to be vulnerable. See the subsection, "Third-Party Kill Bits," in the Vulnerability Information section.

Does this update contain kill bits that were previously released in an Internet Explorer security update?
No, this update does not include kill bits that were previously released in an Internet Explorer security update. We recommend that you install the latest Cumulative Security Update for Internet Explorer.

Why does this advisory not have a security rating associated with it?
This update contains new kill bits for third-party controls. Microsoft does not provide a security rating for vulnerable third-party controls.

Workarounds

Workaround refers to a setting or configuration change that would help block known attack vectors before you apply the update.

  • Prevent COM objects from running in Internet Explorer

    You can disable attempts to instantiate COM objects in Internet Explorer by setting the kill bit for the control in the registry.

    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.

    To set the kill bit for CLSIDs with values of {0d080d7d-28d2-4f86-bfa1-d582e5ce4867} and {29e9b436-dfac-42f9-b209-bd37bafe9317} paste the following text in a text editor such as Notepad. Then, save the file by using the .reg file name extension.

    Windows Registry Editor Version 5.00
    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{0d080d7d-28d2-4f86-bfa1-d582e5ce4867}] "Compatibility Flags"=dword:00000400 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility\{0d080d7d-28d2-4f86-bfa1-d582e5ce4867}] "Compatibility Flags"=dword:00000400 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{29e9b436-dfac-42f9-b209-bd37bafe9317}] "Compatibility Flags"=dword:00000400 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility\{29e9b436-dfac-42f9-b209-bd37bafe9317}] "Compatibility Flags"=dword:00000400

    You can apply this .reg file to individual systems by double-clicking it. You can also apply it across domains by using Group Policy. For more information about Group Policy, see the TechNet article, Group Policy collection.

    Note You must restart Internet Explorer for your changes to take effect.

    Impact of workaround. There is no impact as long as the object is not intended to be used in Internet Explorer.

    How to undo the workaround. Delete the registry keys previously added in implementing this workaround.
