Microsoft Corp. is issuing an emergency fix for a security hole in its browser, Internet Explorer, which was reported yesterday.
The hole has exposed millions of users to having their computers taken over by hackers.
According to The New York Times, Microsoft said it plans to ship a security update, rated ''critical,'' for the browser on December 17. Those with the Windows Update feature activated on their computers will get the patch automatically.
Microsoft said it has seen attacks targeting the flaw only in Internet Explorer 7, the most widely used version, but has cautioned that all other current editions of the browser are vulnerable.
