Apologies for bumping this again, but i have found a new version of GDIPLUS.DLL from microsoft that is not vulnerable and you can use it to overwrite any version of GDIPLUS.DLL you may have that is vulnerable.
You can grab it here -

This is a self extracting exe, just unzip it to C:\Temp or whatever then copy over any vulnerable versions with that one.
