Of course the security risk is there for any type of font file loaded from the URL. Microsoft support loading .EOT files from the @font-face (and has for years). We spend a good part of the past couple of years to make our downloading, validation and temporary installation more robust. Why? Because there were sites that were installing corrupt fonts that would crash or attempt to crash Windows. 

If a UA is going to take complex files, like fonts, from the web, they will need to be ready for fonts that have pointers outside of the font, don't have sentenals at the ends of cmaps, and all sorts of other things of that nature.

The @font-face is not the issue. The only issue is that other UAs have not yet released the ability to get font files that way.

I sort of get the "legal risk," but could you elaborate on what type of security issues are involved and why they don't exist for the existing @font-face mechanism, for example?
