+	  <p>The Expat XML parser mishandles certain kinds of malformed input
+	    documents, resulting in buffer overflows during processing and error
+	    reporting. The overflows can manifest as a segmentation fault or as
+	    memory corruption during a parse operation. The bugs allow for a
+	    denial of service attack in many applications by an unauthenticated
+	    attacker, and could conceivably result in remote code execution.</p>
