Segmentation faults are usually caused by 1 of a few things:
  1. Buggy code (unlikely in passwd)
  2. Bad memory (unlikely if reproducable)
  3. Bad compilation (possible, unless installed from rpm)
  4. Bad version of libc
  5. Hacked system (good passwd replaced with a bad and buggy one)

Any of those sound likely on your system?

Highly unlikely. How can you be so certain that your system has not been cracked?
