<p>This document contains the release notes for FreeBSD 4.10-RELEASE on the Alpha/AXP
hardware platform. It describes new features of FreeBSD that have been added (or changed)
since 4.9-RELEASE. It also provides some notes on upgrading from previous versions of
FreeBSD.</p>
<p>This distribution of FreeBSD 4.10-RELEASE is a release distribution. It can be found

<h2 class="SECT1"><a id="NEW" name="NEW">2 What's New</a></h2>
<p>This section describes the most user-visible new or changed features in FreeBSD since
4.9-RELEASE. Typical release note items document new drivers or hardware support, new
commands or options, major bugfixes, or contributed software upgrades. Security
advisories for the base system that were issued after 4.9-RELEASE are also listed.</p>
<div class="SECT2">
<hr />
<h3 class="SECT2"><a id="SECURITY" name="SECURITY">2.1 Security Advisories</a></h3>
<p>A potential denial of service in <b class="APPLICATION">BIND</b> has been fixed. For
more information, see security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-03:19.bind.asc"
target="_top">FreeBSD-SA-03:19</a>.</p>
<p>A bug with the System V Shared Memory interface (specifically the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=shmat&sektion=2&manpath=FreeBSD+4.10-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">shmat</span>(2)</span></a> system
call) has been fixed. This bug can cause a shared memory segment to reference unallocated
kernel memory. In turn, this can permit a local attacker to gain unauthorized access to
parts of kernel memory, possibly resulting in disclosure of sensitive information, bypass
of access control mechanisms, or privilege escalation. More details can be found in
security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:02.shmat.asc"
target="_top">FreeBSD-SA-04:02</a>.</p>
<p>A potential low-bandwidth denial-of-service attack against the FreeBSD TCP stack has
been prevented by limiting the number of out-of-sequence TCP segments that can be held at
one time. More details can be found in security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:04.tcp.asc"
target="_top">FreeBSD-SA-04:04</a>.</p>
<p>A bug in <b class="APPLICATION">OpenSSL</b>'s SSL/TLS ChangeCipherSpec message
processing could result in a null pointer dereference, has been fixed. This could allow a
remote attacker to crash an <b class="APPLICATION">OpenSSL</b>-using application and
cause a denial-of-service on the system. More details can be found in security advisory
<a href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:05.openssl.asc"
target="_top">FreeBSD-SA-04:05</a>.</p>
<p>Two programming errors in <b class="APPLICATION">CVS</b> have been fixed. They allow a
server to overwrite arbitrary files on the client, and a client to read arbitrary files
on the server when accessing remote CVS repositories. More details can be found in
security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:07.cvs.asc"
target="_top">FreeBSD-SA-04:07</a>.</p>
<p>A bugfix for <b class="APPLICATION">Heimdal</b> rectifies a problem in which it would
not perform adequate checking of authentication across autonomous realms. For more
information, see security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:08.heimdal.asc"
target="_top">FreeBSD-SA-04:08</a>.</p>

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">kadmind</span>(8)</span></a>

<h2 class="SECT1"><a id="UPGRADE" name="UPGRADE">3 Upgrading from previous releases of
FreeBSD</a></h2>
<p>If you're upgrading from a previous release of FreeBSD, you generally will have three
options:</p>
<ul>
<li>
<p>Using the binary upgrade option of <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=sysinstall&sektion=8&manpath=FreeBSD+4.10-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">sysinstall</span>(8)</span></a>.
This option is perhaps the quickest, although it presumes that your installation of
FreeBSD uses no special compilation options.</p>
</li>
<li>
<p>Performing a complete reinstall of FreeBSD. Technically, this is not an upgrading
method, and in any case is usually less convenient than a binary upgrade, in that it
requires you to manually backup and restore the contents of <tt
class="FILENAME">/etc</tt>. However, it may be useful in cases where you want (or need)
to change the partitioning of your disks.</p>
</li>
<li>
<p>From source code in <tt class="FILENAME">/usr/src</tt>. This route is more flexible,
but requires more disk space, time, and technical expertise. More information can be
found in the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html"
target="_top">``Using <tt class="COMMAND">make world</tt>''</a> section of the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>. Upgrading from very old versions of FreeBSD may be problematic; in cases
like this, it is usually more effective to perform a binary upgrade or a complete
reinstall.</p>
</li>
</ul>
<br />
<br />
<p>Please read the <tt class="FILENAME">INSTALL.TXT</tt> file for more information,
preferably <span class="emphasis"><i class="EMPHASIS">before</i></span> beginning an
upgrade. If you are upgrading from source, please be sure to read <tt
class="FILENAME">/usr/src/UPDATING</tt> as well.</p>
<p>Finally, if you want to use one of various means to track the -STABLE or -CURRENT
branches of FreeBSD, please be sure to consult the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/current-stable.html"
target="_top">``-CURRENT vs. -STABLE''</a> section of the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>.</p>
