6. By Martin Pitt

Previous security update scrambled the output fields in the contents
listing, fix that regression.

5. By Martin Pitt

* SECURITY UPDATE: Arbitrary code execution on specially crafted long file
  names (which should not happen in many scenarios, though).
* unzpriv.h, Info macro:
  - Use snprintf() instead of sprintf() as inner formatting function.
  - Use fputs() instead of fprintf() as outer function to ignore leftover
    format strings which might not have been substituted in the inner
    snprintf().
  - Throw away the three different implementations of that macro and use
    just one safe one.
  - CVE-2005-4667

4. By Martin Pitt

* SECURITY UPDATE: Fix file permission modification race.
* unix/unix.c: Use fchmod() instead of chmod() to change permissions on the
  files unzip actually created, not the files another attacker might have
  hardlinked to in the meantime.
* CAN-2005-2475
