If the application is what exposes the URI handling routine to untrusted 
code from the internet, then it's the application's job to make sure that 
code is trusted before exposing system components to it's commands, no?

In this case how is acrobat reader any different than telnetd? If telnetd 
exposes system functions to untrusted users (no password required) who is 
supposed to enforce security? In the case of acrobat reader, it's acrobat 
exposing the system to untrusted sources and it should be that application 
that is responsible for mitigation of attacks via those exposed interfaces.
