Microsoft warns of security flaws
Microsoft Corp. warned of eight "critical" security flaws in its Windows operating system and Office software on Tuesday that could allow attackers to take control of a computer.
Microsoft (Research), whose Windows operating system runs on 90 percent of the world's computers, issued patches to fix the problems as part of its monthly security bulletin. It was the biggest such update since February 2005. The world's biggest software maker defines a flaw as "critical" when the vulnerability could allow a damaging Internet worm to replicate without the user doing anything to the machine.
Six of the critical flaws related to Windows and two affected Office. Microsoft also issued another two security warnings it rated at its second-highest level of "important" for Windows as well as one it gave a severity rating of "moderate."
