+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user or automated system to open a
+    specially crafted DOT file in an application using Graphviz, possibly
+    leading to the execution of arbitrary code.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Graphviz users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=media-gfx/graphviz-2.20.3"</code>
