The giant has released a patch so that Windows doesn't let in hackers when it handles JPEG graphics formats.
The flaw means that attackers can create an image file that will automatically run dodgy code, dump it on a web-site and let Internet Explorer run it.
Anti-virus companies think the glitch is extremely dangerous even though they have not actually seen any code that can exploit the hole.
The flaw affects Windows XP, Windows Server 2003, Office XP, Office 2003, Internet Explorer 6 Service Pack 1, Project, Visio, Picture It and Digital Image Pro. If you are running the recently released SP2 you are protected apparently.
Microsoft also released another patch for a flaw in Office, Publisher, Word and Works which deals with the way WordPerfect file converted.
An attack could be carried out using a malicious WordPerfect document. µ
