Attackers targeting Microsoft Office Excel

On Tuesday, a security advisory was released by Microsoft stating that malicious attackers are targeting versions of its Office Excel with vulnerabilities, not only Windows OS users but also those who use Mac OS.

Included in the affected versions are Microsoft Office Excel 2003 Service Pack 2, Microsoft Office Excel Viewer 2003, Microsoft Office Excel 2002, Microsoft Office Excel 2000, and Microsoft Excel 2004 for Mac.

Microsoft said that Microsoft Office Excel 2007, Microsoft Excel 2008 for Mac, and Microsoft Office Excel 2003 Service Pack 3 do not appear to be vulnerable.

People who open a malicious e-mail attachment or visit a malicious Web site may find that their systems are compromised and that arbitrary remote code is executed. Computers configured to allow the user to have administrative user rights are at greater risk that those with few user rights on the system.
