+  <impact type="normal">
+    <p>
+    A remote attacker could entice a user to open a specially crafted XML
+    document with an application using libxml2, possibly resulting in a
+    high CPU consumption. Note that this vulnerability could also be
+    triggered without user interaction by an automated system processing
+    XML content.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All libxml2 users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/libxml2-2.6.30-r1&quot;</code>
