Today Microsoft released 17 security bulletins which address 40 vulnerabilities affecting Microsoft Office, Windows, Internet Explorer, SharePoint Server and Exchange. This brings the total count for 2010 to 106 bulletins. Of note, only two of the bulletins are rated Critical, 14 are rated Important and one is Moderate. In addition to the bulletins released today, Microsoft is announcing plans to extend the Office File Validation feature currently available in Office 2010, to Office 2007 and 2003. This will help protect those using older versions of Microsoft Office from file parsing vulnerabilities.
