+<title>Installation of Zlib</title>
+
+<para>Zlib has a potential buffer overflow in its
+<emphasis>gzprintf()</emphasis> function, that, though difficult to take
+advantage of, should be taken care of by applying this patch:</para>
+
+<screen><userinput>patch -Np1 -i ../&zlib-patch;</userinput></screen>
+
+<para>Now prepare Zlib for compilation:</para>
+
+<screen><userinput>./configure --prefix=/usr --shared</userinput></screen>
+
+<para>Note: Zlib is known to build its shared library incorrectly if a CFLAGS
+is specified in the environment. If you are using your own CFLAGS variables,
+ensure you add the <emphasis role="strong">-fPIC</emphasis> directive during
+this stage, and remove it afterwards.</para>
+
+<para>Compile the package:</para>
+
+<screen><userinput>make</userinput></screen>
+
+<para>Install the shared libraries:</para>
+
+<screen><userinput>make install</userinput></screen>
+
+<para>Now also build the non-shared libraries:</para>
+<screen><userinput>make clean
+./configure --prefix=/usr
+make</userinput></screen>
+
+<para>This package has a test suite available which can perform a number of
+checks to ensure it built correctly. Should you choose to run it, the
+following command will do so:</para>
+
+<screen><userinput>make test</userinput></screen>
+
+<para>And install the package:</para>
+
+<screen><userinput>make install</userinput></screen>
+
+<para>The shared Zlib library should be installed in the
+<filename>/lib</filename> directory. That way, in the event
+that you must boot without the <filename>/usr</filename>
+directory, vital system programs will still have access to
+the library:</para>
+
+<screen><userinput>mv /usr/lib/libz.so.* /lib</userinput></screen>
+
+<para>The <filename>/usr/lib/libz.so</filename> symlink is
+linked to a file which no longer exists, because we moved
+it. Create a symbolic link to the new location of the
+library:</para>
+
+<screen><userinput>ln -sf ../../lib/libz.so.1 /usr/lib/libz.so</userinput></screen>
+
+<para>Zlib does not install its manual page. Issue the
+following command to install this documentation:</para>
+
+<screen><userinput>cp zlib.3 /usr/share/man/man3</userinput></screen>
