    To be honest, I'm not sure what it is you're looking for...while your subject line states that you want to detect the exploit, your post asks about detecting the vulnerability.

    Which is it?

    If you want to detect the vulnerability, it's relatively trivial. MBSA comes to mind, as does WMI. For WMI, use the Win32_QuickFixEngineering class to enumerate all of the installed patches, and if the patch in question does not appear in the list, then you can assume that it wasn't installed.

    Another option would be to obtain file version information from gdiplus.dll on an unpatched machine, and then compare that to that from a patched machine. Then write a Perl script to connect to each system as a domain admin and pull the file version information from that file. Any system on which the file versioning information does not equal what you found on the patched system should be considered vulnerable.

    I hope that helps...
