But it can't do any real damage, because it has no permissions to do so.

Also, with NX and ASLR, it should be next to impossible to actually do anything beyond crashing the application with a single document.

It's not extremely difficult to see the problem here: if you can't trust your editor if you need to edit your .profile, or if you can't trust it to properly handle its contents -- a program crash is not necessarily involved -- then what good is it to you that you have a secure way of opening it?

Who or what specifies what is or is not permitted?
