Microsoft Flags "Critical" Flaws in Windows and IE
Microsoft has warned of three "critical" security flaws in its Windows operating system that could allow attackers to take control of a computer. One of the critical vulnerabilities appears in some versions of Internet Explorer that could make it possible for an attacker to use the Web browser to take total control of a PC. The other two "critical" vulnerabilities were in the Windows operating system.
The company defines a flaw as "critical" when the vulnerability could allow a damaging Internet worm to replicate without the user doing anything to the machine.
The company also issued another security warning it rated at its second-highest level of "important" for Microsoft Windows as well as one it gave a severity rating of "moderate."
A vulnerability defined as "important" is one where an outsider could break into a machine and gain access to confidential data but not replicate itself to other computers, Microsoft said.
