If you’re a user of Microsoft’s PowerPoint or Excel 2001, you’ll probably want to grab a new
Mac macro vulnerability update
from the Macintosh Business Unit.
The update (a 739k file) addresses a vulnerability that could allow malicious code to run in a Microsoft Excel 2001 for Mac or Microsoft PowerPoint 2001 for Mac file without warning. In an Excel or PowerPoint file, macros can be modified in such a way that they could run without displaying a warning.
According to a note from the MacBU, this could 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, a warning will appear when you open an Excel or PowerPoint file that contains macros.
To install the Office for Macintosh Security Update: Macro Vulnerability, you must first run the Office 2001 for Mac Service Release 1. If you are unsure whether you are using the latest update, you can check the version number of Excel or PowerPoint.
