Microsoft announced it will deliver 13 bulletins Tuesday, February 9, 2010. They will address 26 vulnerabilities in Windows and Office, five of which are rated critical.
The Office related bulletins are both rated Important and would require user action to be exploited (usually in the form of convincing a user to open a specially crafted file). The vulnerabilities only affect older versions of Office so customers on Office 2007 or Office 2008 for Mac will have no actions this month.
Following the bulletin release, those who want more in-depth information can join Adrian Stone and Jerry Bryant for a live webcast where they will go in to detail on each bulletin to give more information and guidance.
