On several machines, I'm still seeing a vulnerable version of
gdiplus.dll in the C:\Winnt\system32 directory, even after I
applied all of MS's MS04-028 patches applicable to the
machines. (Tom Liston's GDI Scan
(http://isc.sans.org/gdiscan.php) actually reveals a few
vulnerable files left, but it's the ones in SYSTEM32 that really worry
me.)
I'm running XP SP2 with Office 2003 SP1 and I also see gdiplus.dll in
C:\WINDOWS\system32. There is something very strange about this file.
Depending on how you look at it, it changes. I have two different versions of
the Res Kit utility filever.exe (details below). They each report a different
version for this file.
U:\>filever C:\WINDOWS\system32\gdiplus.dll
--a-- W32i DLL ENU 5.1.3102.2180 shp 1,700,352 09-05-2001 gdiplus.dll
U:\>filever2 C:\WINDOWS\system32\gdiplus.dll
--a-- W32i DLL ENU 5.1.3097.0 shp 1,700,352 09-05-2001 gdiplus.dll
Even stranger, if you check the very same file using a UNC path, the versions
come out the same. (Rush is the machine in question.)
U:\>filever \\rush\C$\WINDOWS\system32\gdiplus.dll
--a-- W32i DLL ENU 5.1.3097.0 shp 1,700,352 09-05-2001 gdiplus.dll
U:\>filever2 \\rush\C$\WINDOWS\system32\gdiplus.dll
--a-- W32i DLL ENU 5.1.3097.0 shp 1,700,352 09-05-2001 gdiplus.dll
Explorer properties through C:\ reports: 5.1.3102.2180
Explorer properties through UNC reports: 5.1.3097.0
Also, a byte comparison with gdiplus.dll from an unpatched system--which every
tool I tried says is vulnerable--shows the one on the patched system is the
same (i.e., vulnerable).
U:\>fc /b C:\WINDOWS\system32\gdiplus.dll
\\UNPATCHED\C$\WINDOWS\system32\gdiplus.dll
Comparing files C:\WINDOWS\SYSTEM32\gdiplus.dll and
\\UNPATCHED\C$\WINDOWS\SYSTEM32\GDIPLUS.DLL
FC: no differences encountered
I am guessing this has something to do with the side-by-side dll thing, but I
don't really know how it works. Anyone know? Makes it hard to know if you are
really patched.
Versions of filever.exe:
U:\>filever L:\Windows\Tools\FILEVER.EXE
----- W32i APP ENU 5.0.1472.1 shp 40,208 01-07-1997 filever.exe
May have come from NT Res Kit.
U:\>filever "C:\Program Files\Support Tools\filever2.exe"
--a-- W32i APP ENU 5.1.2600.0 shp 12,800 08-17-2001 filever2.exe
This one came from XP SP2 support tools.

A regedit search shows that C:\Winnt\System32\gdiplus.dll is

The Value is the path/file name and the Data is "1."
Same here.
