Introduction

Beginning in Microsoft Security Advisory MS10-105, the security update that is described in the security advisory lets users and administrators control when and how Microsoft Office loads images in Office programs by setting the "Allow List" in the registry.

For more information about Microsoft Security Advisory MS10-105, click the following article number to go to the article in the Microsoft Knowledge Base:

More Information

How to enable the graphics filter "Allow List"

Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround, but we are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.

The "Allow List" and the enabled graphic filters can be set manually for a single computer or by using a Group Policy setting.

The graphic filters that you have to enable must be added to the following registry subkeys:


For a single computer:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Common\Security\AllowLists\GraphicsFilterImport

For a single computer that is running a 64-bit operating system:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\Common\Security\AllowLists\GraphicsFilterImport

For a Group Policy setting:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Office\Common\Security\AllowLists\GraphicsFilterImport
To enable the "Allow List" for graphic filters, the AllowListEnabled value must be set to 1. To disable the "Allow List," the AllowListEnabled value must be set to 0.

Note If the AllowListEnabled value does not exist, you must create it as a REG_DWORD type.

When the AllowListEnabled value is enabled, you can specify the list of graphic filters to enable by adding the graphic filters as a string value that has the name FILTER.FLT (where FILTER.FLT is replaced by the actual name of the filter) together with the version number of the filter. The filter version number must use the following format:

XXXX.YYYY.ZZZZ.WWWW
Note When you set the AllowListEnabled value to 1, the default list of enabled graphic filters is removed. To re-enable the default graphic filters and add the CGMIMP32.FLT graphic filter, you must specify the filters in the "Allow List."

The following table shows an example of the "Allow List":
