<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.

<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.

<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.
