The <application>Ghostscript</application> build system is not

<para>

<application>Ghostscript</application> includes (old) copies of

several libraries. Some of these seem to have been patched to fix known
|
|
vulnerabilities, but others of these copies are less-well maintained.
|
|
To ensure that any future fixes are applied throughout the whole system,
|
|
it is recommended that you first install the released versions of these
|
|
libraries and then configure <application>Ghostscript</application>
|
|
to link to them.

</para>

<para>

If you have downloaded the fonts, unpack them to

<filename class="directory">/usr/share/ghostscript</filename> and ensure

the ownership of the files are

<systemitem class="username">root</systemitem>:
