Microsoft on Tuesday delivered a beefy set of patches addressing 40 vulnerabilities across Windows, Office, Internet Explorer, SharePoint Server and Exchange.
Of the bunch, two bulletins were rated critical and 14 were important.
As expected, MS10-090 was the biggest bulletin. This one addressed a bevy of IE problems affecting IE 6, 7 and 8.

Microsoft said in its blog post that it also patched three vulnerabilities in Windows OpenType Font driver. There are no reported attacks on the font driver.
Microsoft also said it addressed the last known vulnerability exploited by the Stuxnet malware. The Stuxnet patch isn't deemed critical.
