I believe the security feature is the ability to disable Javascript code that is included within the pdf file. A pdf reader implemented in Javascript is perfectly capable of doing that.

Not only that, but being able to render via js would (and thus avoid calling out to any plugin code) would be able to take advantage of sandboxing too I imagine.

How do you evaluate the PDF's JavaScript in an interpreter that is distinct from the renderer's?
