Microsoft has issued a warning about a serious vulnerability in all versions of its Internet Explorer (IE) browser.
If exploited by a booby-trapped webpage the bug would allow attackers to take control of an unprotected computer.
Code to exploit the bug has already been published though Microsoft said it had no evidence it was currently being used by hi-tech criminals.

The bug revolves around the way that IE manages a computer's memory when processing Cascading Style Sheets - a widely used technology that defines the look and feel of pages on a website.
