Security Bulletins From Microsoft Office 2007 - All Critical

Microsoft released only four new Security Bulletins, but all four were rated as Critical by Microsoft. Aside from being Critical, the four Security Bulletins had something else in common- they are all related to Microsoft Office.

Tere are vulnerabilities in Excel, Outlook, Office, and Office Web Components. In each case, the vulnerabilities could potentially be exploited to allow an attacker to control the target system and execute malicious code remotely. Microsoft Security Bulletins: March 2008.
