+    <impact type="high">
+        <p>in the Perl background extension, when an attacker can
+control the data written to the user&#39;s terminal and certain options are set.
+
+The &#34;background&#34; extension is automatically loaded if certain X resources are set such as &#39;transparent&#39; (see the full list at the top of src/perl/background[1]). So it is possible to be using this extension without realising it.</p>

+    </workaround>
