Microsoft has released a security update for Microsoft Excel 2000. The following "Article contents" section describes the information that this article contains about the security update.


A security vulnerability exists in Microsoft Excel 2000 that could allow arbitrary code to run when you open a maliciously modified spreadsheet. This vulnerability exists because of a problem in the way that Excel 2000 interprets data from a spreadsheet where certain properties have been maliciously modified. If this vulnerability were successfully exploited, an attacker could craft a malicious spreadsheet that could cause code of the attacker’s choice to be executed automatically when you open the maliciously modified spreadsheet. This update resolves this vulnerability so that Excel 2000 spreadsheets are handled appropriately.
