One of the vectors that has been mentioned early on is the infection of a system through the WMF exploit even when the exploited file was downloaded through a dos command shell. At first this seemed absurd, but it appeared that Google Desktop search was indexing files dynamically and once the file was downloaded it indexed the file and triggered the vulnerability. There is word that Microsoft’s indexing service does likewise – although Microsoft has only said that they’re “looking into reports”. Incidents.org is saying that they think this may be the giant white elephant no one is talking about. I certainly would shudder to think if machines on a network are indexing a network share and manage to subvert every machine running an indexing share….

Third Party WMF patch
The F-secure blog is reporting on a third party patch for the WMF exploit. I have not tested it, it seems to come from a knowledgable source though. As I’m writing this though, the thought strikes me that a really nasty trick would be a claimed fix that actually exploited the vulnerability. It pays to check up on the source of ANY third-party fix for Windows (or any other operating system or software suite…) Anyway, this seems to be a good source though. He’s the primary author of IDA Pro (Interactive Disassembler Pro).
