Microsoft today said it will deliver five security updates on Tuesday, all affecting Windows and all ranked "critical," the company's highest threat rating.

Unlike some months when Microsoft provides its usual advance notification for upcoming updates, this time there weren't any hints of what may be coming, said Andrew Storms, director of security operations at nCircle Network Security.

"It's a foggy advance warning," said Storms. "I'm a little bit at a loss for words. There doesn't seem to be anything here that has been disclosed publicly."

That didn't stop Storms from speculating, though. "We could see another ATL update," he said, referring to the flaws in Active Template Library (ATL), a Microsoft code "library" that it and third-party developers use to create software.
