<p>This document contains the release notes for FreeBSD 5.5-RELEASE on the NEC PC-98x1
hardware platform. It describes recently added, changed, or deleted features of FreeBSD.
It also provides some notes on upgrading from previous versions of FreeBSD.</p>
<p>This distribution of FreeBSD 5.5-RELEASE is a release distribution. It can be found at
<a href="ftp://ftp.FreeBSD.org/" target="_top">ftp://ftp.FreeBSD.org/</a> or any of its
mirrors. More information on obtaining this (or other) release distributions of FreeBSD
can be found in the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/mirrors.html"
target="_top">``Obtaining FreeBSD'' appendix</a> to the <a
href="http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/" target="_top">FreeBSD
Handbook</a>.</p>
<p>All users are encouraged to consult the release errata before installing FreeBSD. The
errata document is updated with ``late-breaking'' information discovered late in the
release cycle or after the release. Typically, it contains information on known bugs,
security advisories, and corrections to documentation. An up-to-date copy of the errata
for FreeBSD 5.5-RELEASE can be found on the FreeBSD Web site.</p>
<p>FreeBSD 5.5-RELEASE is the last planned release on the 5.5-STABLE branch. The FreeBSD
development community is currently focusing its efforts on the 6-STABLE and CURRENT
codelines. No new major features are planned for the 5.5-STABLE branch, although minor
updates and bugfixes may be merged at the discretion of individual developers. The
FreeBSD security team will support the 5.5-RELEASE-based security branch with advisories
and security patches until the end-of-life date documented at <a
href="http://security.freebsd.org/" target="_top">http://security.freebsd.org/</a> (as of
this writing, 31 May 2008).</p>

<hr />
<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
5.4-RELEASE.</p>
<p>Typical release note items document recent security advisories issued after
5.4-RELEASE, new drivers or hardware support, new commands or options, major bug fixes,
or contributed software upgrades. They may also list changes to major ports/packages or
release engineering practices. Clearly the release notes cannot list every single change
made to FreeBSD between releases; this document focuses primarily on security advisories,
user-visible changes, and major architectural improvements.</p>

<h3 class="SECT2"><a id="SECURITY" name="SECURITY">2.1 Security Advisories</a></h3>
<p>A bug in the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=tcpdump&sektion=1&manpath=FreeBSD+5.5-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">tcpdump</span>(1)</span></a>
utility which allows a malicious remote user to cause a denial-of-service by using
specially crafted packets, has been fixed. For more information, see security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:10.tcpdump.asc"
target="_top">FreeBSD-SA-05:10.tcpdump</a>.</p>
<p>Two problems in the <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">gzip</span>(1)</span></a> utility
have been fixed. These may allow a local user to modify permissions of arbitrary files
and overwrite arbitrary local files when uncompressing a file. For more information, see
security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:11.gzip.asc"
target="_top">FreeBSD-SA-05:11.gzip</a>.</p>
<p>A bug has been fixed in <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=ipfw&sektion=4&manpath=FreeBSD+5.5-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipfw</span>(4)</span></a> that
could cause packets to be matched incorrectly against a lookup table. This bug only
affects SMP machines or UP machines that have the <tt class="LITERAL">PREEMPTION</tt>
kernel option enabled. More information is contained in security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:13.ipfw.asc"
target="_top">FreeBSD-SA-05:13.ipfw</a>.</p>
<p>Two security-related problems have been fixed in <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=bzip2&sektion=1&manpath=FreeBSD+5.5-RELEASE">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">bzip2</span>(1)</span></a>. These
include a potential denial of service and unauthorized manipulation of file permissions.
For more information, see security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:14.bzip2.asc"
target="_top">FreeBSD-SA-05:14.bzip2</a>.</p>
<p>Two problems in FreeBSD's TCP stack have been fixed. They could allow attackers to
stall existing TCP connections, creating a denial-of-service situation. More information
is contained in security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:15.tcp.asc"
target="_top">FreeBSD-SA-05:15.tcp</a>.</p>
<p>Two buffer overflows in the zlib library has been corrected. More information can be
found in security advisory <a
href="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:16.zlib.asc"
target="_top">FreeBSD-SA-05:16.zlib</a> and <a

target="_top">FreeBSD-SA-05:18.zlib</a>.</p>
<p>A security vulnerability that could allow processes running inside a <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">jail</span>(2)</span></a> to gain

target="_top">FreeBSD-SA-05:17.devfs</a>.</p>
<p>A programming error in the <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">ipsec</span>(4)</span></a>
implementation, which resulted in AES-XCBC-MAC authentication using a constant key, has
been corrected. More details are in security advisory <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+5.5-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>
<div class="IMPORTANT">

<p><b>Important:</b> Upgrading FreeBSD should, of course, only be attempted after backing
