Flaws Found in Windows Vista

Microsoft is facing an early crisis of confidence in the quality of its Windows Vista operating system as computer security researchers and hackers have begun to find potentially serious flaws in the system that was released to corporate customers late last month.

Computer security researchers and hackers have found more flaws in Windows Vista, the long-awaited update to the Windows operating system, according to CNN Monday.

One programmer said it was possible to increase a user's privileges on all of the company's recent operating systems, including Vista, while a computer security firm said that it found five other vulnerabilities, including one error in the software code underlying the company's new Internet Explorer 7 browser.

On Saturday, Nicole Miller, a Microsoft spokeswoman, said the company was investigating the reported browser flaw and that it was not aware of any attacks attempting to use the vulnerability. Microsoft officials were not immediately available for comment on Monday.
