     107      <para>
     108        PIE (position-independent executable) is a technique to produce
     109        binary programs that can be loaded anywhere in memory.  Without PIE,
     110        the security feature named ASLR (Address Space Layout Randomization)
     111        can be applied for the shared libraries, but not the executable
     112        itself.  Enabling PIE allows ASLR for the executables in addition to
     113        the shared libraries, and mitigates some attacks based on fixed
     114        addresses of sensitive code or data in the executables.
     115      </para>
     116      <para>
     117        SSP (Stack Smashing Protection) is a technique to ensure
     118        that the parameter stack is not corrupted. Stack corruption can
     119        for example alter the return address of a subroutine,
     120        which would allow transferring control to some dangerous code
     121        (existing in the program or shared libraries, or injected by the
     122        attacker somehow) instead of the original one.
