+	  <p>
+	    When parsing and serializing a crafted XML document, REXML gem
+	    (including the one bundled with Ruby) can create a wrong XML
+	    document whose structure is different from the original one.
+	    The impact of this issue highly depends on context, but it may
+	    lead to a vulnerability in some programs that are using REXML.
