1.7 millert 85: If the Postfix sendmail replacement is installed on a system an
86: attacker may be able to gain root privileges on the local host via
87: sudo(8) which runs the mailer as root with an environment inherited

210: The 2.9 CD cover states that XFree86 3.3.6-current is included. This is only half-true.
211: In fact, the XFree86 included for all architectures is 4.0.3. On the i386, the
212: 3.3.6 Xservers have also been included, because 4.0.3 still has weak support for
