The widely-reported flaw in how .WMF files are handled by Windows operating systems (and third-party software) may be less serious for
some Windows users than originally thought.
E-week's Larry Seltzer is reporting that it is WinXP and Server 2003 machines that are the most vulnerable. It is still possible for earlier versions of Windows to be affected, but less likely. Seltzer suggests that the available unofficial patch be considered for WinXP and Server 2003 machines only.
I'm certainly not sorry to find that only a small number of machines in my organization are vulnerable. That said, I'm also not sorry I went into the office and did the workaround on Win2000 machines yesterday.
I am sorry so many offices, including mine, are currently stuck on the Microsoft treadmill.
Keep your eyes open for more information on this flaw, particularly if you have WinXP or Server 2003 machines.
