+	  <p>A stack overflow vulnerability exists in the libexpat library due
+	  to the way it handles recursive entity expansion in XML documents.
+	  When parsing an XML document with deeply nested entity references,
+	  libexpat can be forced to recurse indefinitely, exhausting the stack
+	  space and causing a crash.  This issue could lead to denial of
+	  service (DoS) or, in some cases, exploitable memory corruption,
+	  depending on the environment and library usage.</p>
