Insecure hardware (was Re: gets(3) nonsense)

[Stuart Gathman]

Although the code space can't be modified, a virus can selectively
execute portions of the code space in any desired sequence by modifying
the stack in a split I&D process.  It doesn't take much imagination
to see what might be done with the library code included with a
typical program.  exec() is only one possibility.
