[Gnumed-devel] data executable / execution (?)

[James Busser]

I was listening to a feature (Security Now podcast @ approx 54:20)  
about Address Space Layout Randomization (ASLR) as well as Data  
Execution Prevention (DEP)

Windows is only now working to implement these in Vista however they  
are having to make exception for various softwares. In 64 bit Windows  
however, I understand that these modes are non-optional and certain  
software that does not respect the above will simply not run.

Does GNUmed is its dependencies have any requirement for data to be  
executable and, if so, would its future dependability depend on  
things like the implementation of an "image base" (??) or virtualized  
allocation?
