Microsoft has described three of the vulnerabilities as critical.

As part of its monthly patch distribution, Microsoft has issued six security updates yesterday, three of which are critical. The critical patches address remote code execution flaws in Internet Explorer, Plug and Play as well as in Windows's Print Spooler Service.

"Remote code execution flaws can allow unauthorised and remote access to a computer," said Carole Theriault, security consultant for Sophos. "It would certainly be wise for all affected users to patch their computers now before someone finds a way to exploit the loophole."
