ZDNET.co.uk: "A newly discovered bug in Microsoft's Internet Explorer Web
browser could let malicious hackers read the e-mail and computer
files of some unsuspecting people.
Bug tracker Georgi Guninski said the exploit is activated when a
surfer using Internet Explorer 5 loads a malicious Web page. The
surfer's network also must be running Microsoft's Exchange 2000
server for the bug to show up."
