Say what? 'Vista's cover is blown'

Call it the curse of the cursor.

Microsoft this week had to jump the gun on its monthly release of software patches because of troubles stirred up by animated cursors in Windows--cybercrooks were slipping through the hole to attack Windows PCs. As it turns out, the cursor patch itself is also a bit of a troublemaker.

Tuesday's release of that "critical" patch prompted some security experts to chide Microsoft for its claims about the security capabilities of Windows Vista.

"As far as software vulnerabilities go, Vista's cover is blown," said Nand Mulchandani, a vice president at Determina, the company that discovered the bug. "It is not Superman; it is just a human being...Vista is going to be very similar to the other operating systems Microsoft has delivered in terms of bugs. "
