Resolution

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem.

NOTE: The Microsoft Office products that are listed at the beginning of this article were developed in an era when the security threat was very different, and as a result, they do not include the improved security architecture of more recent versions of Office, such as Macro security. Because Macro security is not included in Microsoft Office 97, the fix that is described in this article may be compromised. For more information about how this fix may be compromised, see the "More Information Section" of this article. Microsoft recommends that customers use Microsoft Office 2002 for the highest level of security.

IMPORTANT: Before you install the Word 97 Patch, install the Microsoft Word 97 Service Release 2b (SR-2b). Although the Word 97 Patch will install if you do not have Microsoft Word 97 SR-2b installed on your computer, the Word 97 Patch is only supported by Microsoft on Word 97 SR-2b. For more information about how to install Microsoft Word 97 Service Release 2b (SR-2b), visit the following Microsoft Web site:
http://www.microsoft.com/downloads/details.aspx?FamilyID=BEFD7842-602E-42B0-89D2-6BE39F1167C1
To resolve this problem, contact Microsoft Product Support Services (PSS) to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix has the file attributes (or later) that are listed in the following table. The dates and times for these files are listed in coordinated universal time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time tool in Control Panel.
   Date         Time      Version     Size     File name     
   --------------------------------------------------------
                          8.0.0.9011  5,211KB  Winword.exe
   5-Oct-2002   02:16 am  8.0.0.9011  1,132KB  Wwintl32.dll
				

NOTE: After you install the Word Patch you cannot remove it. The Word Patch changes the default behavior of some Word fields. If you want the Word fields to behave as they did before you installed the Word Patch set the FieldCalcSecurityLevel registry key to 0.

The Behavior Changes That Occur in the Word Fields When You Install the Word Patch

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

More information

The updates to Word that are described in Microsoft Security Bulletin MS02-059 prevent several Word fields from updating automatically, and by default, prompts the user to allow updates to some linked data sources. Word 97 users should be aware that after they apply the fix to Word 97, it is still possible for a malicious user to create a document with crafted Word fields intended to gather unauthorized data. Because Office 97 did not include the ability to trust macros, it is not possible to detect who authored any particular macro when presented with the new error message. A macro can be crafted such that upon opening a document, it automatically updates all fields mimicking the manual re-calculation behavior in the document, therefore exposing the user to the same vulnerability as if the Word 97 patch had not been applied.
