CVE-2008-0216 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-0216):
  The ptsname function in FreeBSD 6.0 through 7.0-PRERELEASE does not properly
  verify that a certain portion of a device name is associated with a pty of a
  user who is calling the pt_chown function, which might allow local users to
  read data from the pty from another user.

CVE-2008-0217 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-0217):
  The script program in FreeBSD 5.0 through 7.0-PRERELEASE invokes openpty,
  which creates a pseudo-terminal with world-readable and world-writable
  permissions when it is not run as root, which allows local users to read data
  from the terminal of the user running script.

actually the openpty function is patched too in freebsd-lib-6.2-r4

as far as I understand it, the script program doesn't need any modification
