87: attacker may be able to gain root privileges on the local host via
88: sudo(8) which runs the mailer as root with an environment inherited

212: In fact, the XFree86 included for all architectures is 4.0.3. On the i386, the
213: 3.3.6 Xservers have also been included, because 4.0.3 still has weak support for
