Dangerous Bug in Windows XP Turns Windows Help into Windows Hell
By on June 22nd, 2010

red-x-ico If you haven’t already, you need to fix your Windows XP or Windows Server 2003 machines to protect you against a recently discovered flaw. It’s called the HCP Flaw.

Is it dangerous? Yes, all you have to do is view a specially coded page on the net, and your control over your PC can be stolen right out from under you.

Here’s what the problem is. A flaw in the Windows Help and Support Center (helpctr.exe) was discovered recently, and shortly after that, the information telling people how to take advantage of it was also published. It’s good when Windows flaws are reported, but it’s very bad when the information on how to use those flaws is also broadcast. You can bet that there are some black hats out there already infecting PCs with this new flaw.

There is a fix out from Microsoft. Go to this page and click on the Fixbutton to download the fix (KB2219475).

This fixisn’t a real solution. It disables the Help and Support Center in Windows, but if you are like me, you never use it anyway. Some time after Microsoft offers a real update to solve this problem, I’ll go back and re-enable the help center.

People running running Windows 7, Vista, 2000 or Server 2008 are safe from this bug. The affected operating systems are:

Microsoft Windows Server 2003 Service Pack 2, when used with:
Microsoft Windows Server 2003, Standard Edition (32-bit x86)
Microsoft Windows Server 2003, Enterprise Edition (32-bit x86)
Microsoft Windows Server 2003, Datacenter Edition (32-bit x86)
Microsoft Windows Server 2003, Web Edition
Microsoft Windows Server 2003, Datacenter x64 Edition
Microsoft Windows Server 2003, Enterprise x64 Edition
Microsoft Windows Server 2003, Standard x64 Edition
Microsoft Windows XP Professional x64 Edition
Microsoft Windows Server 2003, Datacenter Edition for Itanium-Based Systems
Microsoft Windows Server 2003, Enterprise Edition for Itanium-based Systems
Microsoft Windows XP Service Pack 2, when used with:
Microsoft Windows XP Home Edition
Microsoft Windows XP Professional
Microsoft Windows XP Service Pack 3, when used with:
Microsoft Windows XP Home Edition
Microsoft Windows XP Professional

Here’s a good place to find more information on the HCP Flaw if you need it.
