1.7 millert 59: If the Postfix sendmail replacement is installed on a system an
60: attacker may be able to gain root privileges on the local host via
61: sudo(8) which runs the mailer as root with an environment inherited
62: from the invoking user. While this is a bug in sudo it is not
63: believed to be possible to exploit when sendmail (the mailer that
64: ships with OpenBSD) is the mailer. As of version 1.6.5, sudo passes
65: the mailer an environment that is not subject to influence from the
1.8 millert 66: invoking user.<br>

1.4 millert 72: A security issue exists in the lpd daemon that may allow an attacker
73: to create arbitrary new files in the root directory. Only machines
74: with line printer access (ie: listed in either /etc/hosts.lpd or
75: /etc/hosts.equiv) may be used to mount an attack and the attacker
76: must have root access on the machine. OpenBSD does not start lpd
77: in the default installation.

89: A security hole exists in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=uuxqt&sektion=8">uuxqt(8)</a>
90: that may allow an attacker to run arbitrary commands as user uucp and
91: use this to gain root access.
92: The UUCP execution daemon, uuxqt(8), has a bug in its command line
93: parsing routine that may allow arbitrary commands to be run. Because
94: some UUCP commands are run as root (and daemon) from cron it is possible
95: to leverage compromise of the UUCP user to gain root.

184: The 2.9 CD cover states that XFree86 3.3.6-current is included. This is only half-true.
185: In fact, the XFree86 included for all architectures is 4.0.3. On the i386, the
186: 3.3.6 Xservers have also been included, because 4.0.3 still has weak support for
187: some devices which 3.3.6 supported better.
