Microsoft today fixed a critical hole in Windows and two less serious holes in Office in one of the lightest Patch Tuesdays in recent history.

The critical bulletin, MS11-035, fixes a vulnerability in the Windows Internet Name Service (WINS) that "could allow remote code execution if a user received specially crafted malware on an affected system running the WINS service," according to the bulletin advisory. It affects Windows Server 2003 and 2008.

WINS is not installed on the affected operating system software by default, so only customers who manually install it are affected and will be offered the update, Microsoft said.
