1.7 millert 77: If the Postfix sendmail replacement is installed on a system an
78: attacker may be able to gain root privileges on the local host via
79: sudo(8) which runs the mailer as root with an environment inherited
80: from the invoking user. While this is a bug in sudo it is not
81: believed to be possible to exploit when sendmail (the mailer that

113: to leverage compromise of the UUCP user to gain root.

202: The 2.9 CD cover states that XFree86 3.3.6-current is included. This is only half-true.
203: In fact, the XFree86 included for all architectures is 4.0.3. On the i386, the
204: 3.3.6 Xservers have also been included, because 4.0.3 still has weak support for
205: some devices which 3.3.6 supported better.
