Unknown vulnerability in Microsoft Excel 2000, 2002, 2001 for Mac, and v.X for Mac allows remote attackers to execute arbitrary code via a malicious file containing certain parameters that are not properly validated.

Microsoft Word and Excel allow remote attackers to steal sensitive information via certain field codes that insert the information when the document is returned to the attacker, as demonstrated in Word using (1) INCLUDETEXT or (2) INCLUDEPICTURE, aka "Flaw in Word Fields and Excel External Updates Could Lead to Information Disclosure."

Buffer overflow in various Microsoft applications for Macintosh allows remote attackers to cause a denial of service (crash) or execute arbitrary code by invoking the file:// directive with a large number of / characters, which affects Internet Explorer 5.1, Outlook Express 5.0 through 5.0.2, Entourage v. X and 2001, PowerPoint v. X, 2001, and 98, and Excel v. X and 2001 for Macintosh.
