A Google security researcher had recently made public a vulnerability in the Windows Help Center which could could allow remote code execution, thereby exposing a number of Windows users to this vulnerability.
Microsoft had released a Microsoft Security Advisory about this issue for IT professionals. The security advisory contains additional security-related information.
Microsoft has now released a Fixit solution to fix this problem in the Windows Help Center.
To fix this problem automatically, download the Fixit from Microsoft KB2219475. Click the Fix this problem link under the “Enable this fix” heading. Then, click Run in the File Download dialog box and follow the steps in the wizard.
To undo the fix and restore the original settings, click the Fix this problem link under the “Disable this fix” heading. Then, click Run in the File Download dialog box and follow the steps in the wizard.
This wizard may be in English only. However, the automatic fix also works for other language versions of Windows. If you are not on a Windows computer that has the problem, you can save the automatic fix to a flash drive or to a CD, and then you can run it on the computer that has the problem.
Applies to Microsoft Windows Server 2003 & Windows XP.
