It looks like moments after the fix for the WMF vulnerability was released some researches have found two more flaws that were previously unknown. They were discovered by a hacker that goes by the name cocoruder. All of these vulnerabilities surround the dll that allows users to preview images.
With this news in mind we have decided to completely disable image previews on our systems until Microsoft has this whole mess sorted out. The way to do it is very simple:
Click on start, then run, and type the following:
regsvr32 /u shimgvw.dll
Click OK, and image previews will be disabled.
When Microsoft finally gets their act together on this issue and releases more patches you can turn it back on by doing the same, but changing the command line to:
regsvr32 shimgvw.dll
