The machine is a Windows XP SP1 completly patched with Office 2000 SP 3 
completly patched.

I don't have any kind of imaging programs installed (Photoshop, Picture It, 
etc)

The output from the SANS tool is:

Scan Complete.

Does anybody know what the content of the WinSxS directory under the windows 
installation path is?

How did you test this (and on what platform), and why do you propose

that the SANS tool is delivering more accurate results than the GDI tool

delivered by Microsoft?



I tested the SANS tool against a properly patched XP system on Friday

and found it to false positive on many of the locations it said it

wouldn't test on.  Additionally, I found it to alert on MS09.dll, on an

XP system.  Our understanding from Microsoft is that MS09.DLL only needs

to be updated to be fully compatible with an updated GDIPLUS.DLL in the

system directory, it is not directly vulnerable.



So, it would be good to know what you found.



Best,

From an earlier discussion on Bugtraq:

From the page:

"from what I understand the WinSxS folder is a housing area for
shared .dll's to eliminate dll hell."

Here's a couple more links:
