Description of the Excel 2002 update: October 4, 2001

Microsoft has released an update to Microsoft Excel 2002. This update addresses a vulnerability that may allow malicious code to run in an Excel file without warning. Under normal circumstances, you receive a warning in Excel 2002 when you open a document containing macros. However, it is possible for a malicious user to modify the macros in such a way that a macro can run with no warning being issued. This scenario may cause damage to data or allow unauthorized retrieval of data from your system when you visit a Web site or open an e-mail message. After you apply this update, you will receive a warning before you open an Excel file containing macros.

For more information about this issue, see the Microsoft Security Bulletin MS01-50: Malformed Excel or PowerPoint Document Can Bypass Macro Security (http://www.microsoft.com/technet/security/bulletin/ms01-050.mspx)

This article explains how to download and install the Microsoft Excel 2002 Update: October 4, 2001.
