<a name=lpd>
<li><font color=#009000><strong>014: SECURITY FIX: August 29, 2001</strong></font><br>
A security hole exists in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=lpd&sektion=8">lpd(8)</a>
that may allow an attacker with line printer access to gain root
privileges. A machine must be running lpd to be vulnerable (OpenBSD
does not start lpd by default). Only machines with line printer
access (ie: listed in either /etc/hosts.lpd or /etc/hosts.equiv)
may be used to mount an attack.

A security hole exists in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sendmail&sektion=8">sendmail(8)</a>
that may allow an attacker on the local host to gain root privileges by
specifying out-of-bounds debug parameters.

<a name=nfs>
<li><font color=#009000><strong>012: SECURITY FIX: July 30, 2001</strong></font><br>
A kernel buffer overflow exists in the NFS mount code. An attacker may
use this overflow to execute arbitrary code in kernel mode. However,
only users with <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mount&sektion=2">mount(2)</a>
privileges can initiate this attack. In default installs, only super-user has
mount privileges. The kern.usermount <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sysctl&sektion=3">sysctl(3)</a> controls whether other users have mount privileges.

<li><font color=#009000><strong>011: RELIABILITY FIX: July 15, 2001</strong></font>
<br>
The
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=packages&sektion=7&format=html">packages(7)</a>
subsystem incorrectly accepts some package dependencies as okay (see
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=packages-specs&sektion=7&format=html">packages-specs(7)</a>
for details).
<br>
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.9/common/011_pkg.patch">A source code patch exists which remedies the problem</a>,
by forcing <code>/usr/sbin/pkg</code> to be more careful in checking
version numbers.

<li><font color=#009000><strong>008: RELIABILITY FIX: June 15, 2001</strong></font>
<br>
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=twe&sektion=4&format=html">twe(4)</a>
mishandles the DMA mapping resulting in a kernel panic on unaligned data
transfers, induced by programs such as
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=disklabel&sektion=8&format=html">disklabel(8)</a>

<li><font color=#009000><strong>007: SECURITY FIX: June 15, 2001</strong></font><br>
A race condition exists in the kernel <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=execve&sektion=2&format=html">execve(2)</a> implementation that opens a small window of vulnerability for a non-privileged user to <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ptrace&sektion=2&format=html">ptrace(2)</a> attach to a suid/sgid process.

<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sshd&sektion=8&format=html">sshd(8)</a>
allows users to delete arbitrary files named "cookies" if X11
forwarding is enabled. X11 forwarding is disabled by default.

<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=isakmpd&sektion=8&format=html">isakmpd(8)</a>
will fail to use a certificate with an identity string that is
exactly N * 8 bytes long.
<br>
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.9/common/004_isakmpd.patch">A source code patch exists which remedies the problem</a>.
<p>
<li><font color=#009000><strong>003: DOCUMENTATION FIX: June 1, 2001</strong></font><br>
The 2.9 CD cover states that XFree86 3.3.6-current is included. This is only half-true.
In fact, the XFree86 included for all architectures is 4.0.3. On the i386, the
3.3.6 Xservers have also been included, because 4.0.3 still has weak support for
some devices which 3.3.6 supported better.
<p>
<a name=fts></a>
<li><font color=#009000><strong>002: SECURITY FIX: May 30, 2001</strong></font><br>
Programs using the <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=fts&sektion=3&format=html">fts(3)</a>
routines (such as rm, find, and most programs that take a <b>-R</b>
flag) can be tricked into changing into the wrong directory if the
parent dir is changed out from underneath it. This is similar to
the old fts bug but happens when popping out of directories, as
opposed to descending into them.
<br>
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.9/common/002_fts.patch">A source code patch exists which remedies the problem</a>.
This is the second version of the patch.
<p>
<a name=sendmail></a>
<li><font color=#009000><strong>001: SECURITY FIX: May 29, 2001</strong></font><br>
The signal handlers in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sendmail&sektion=8&format=html">sendmail(8)</a> contain code that is unsafe in the
context of a signal handler. This leads to potentially serious
race conditions. At the moment this is a theoretical attack only
and can only be exploited on the local host (if at all).<br>
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.9/common/001_sendmail.patch">A source code patch exists</a> which remedies the problem by updating sendmail to version 8.11.4.
</ul>

<a name=i386></a>
<li><h3><font color=#e00000>i386</font></h3>
<ul>
<a name=nvidia></a>
<li><font color=#009000><strong>010: RELIABILITY FIX: Jul 9,
2001</strong></font></br>
The nVidia driver for XFree86 4.0.3 is incorrectly restoring the text
mode palette upon exit of the X server. <a
href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.9/i386/010_nvidia.patch">
A source code patch exists</a> which remedies the problem.
To avoid rebuilding the whole XFree86 tree, an updated binary driver
is also available
<a
href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.9/i386/nv_drv.o">here
</a>. Just grab it, copy it to /usr/X11R6/lib/modules/drivers/ and
restart your X server.
<p>
<a name=XF86Setup></a>
<li><font color=#009000><strong>009: RELIABILITY FIX: Jun 23,
2001</strong></font><br>
The XF86Setup(1) configuration tool for XFree86 3.3.6 is producing
corrupted /etc/XF86Config files.
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.9/i386/009_XF86Setup.patch">
A source code patch exists</a> which remedies the problem by linking
XF86Setup against the XFree86 3.3.6 version of libXxf86vm.a.
<p>
<li>When using a PS/2 keyboard with an MSI K7T Pro2A motherboard, it may be
necessary to disable the "USB Keyboard Support" and
"USB Mouse Support" options in the BIOS. Otherwise, the i8042
keyboard controller doesn't acknowledge commands, confusing OpenBSD.
