+	  <p>QXmlSimpleReader in Qt versions prior to 5.2 supports
+	    expansion of internal entities in XML documents without
+	    placing restrictions to ensure the document does not cause
+	    excessive memory usage. If an application using this API
+	    processes untrusted data then the application may use
+	    unexpected amounts of memory if a malicious document is
+	    processed.</p>
+	  <p>It is possible to construct XML documents using internal
+	    entities that consume large amounts of memory and other
+	    resources to process, this is known as the 'Billion Laughs'
+	    attack. Qt versions prior to 5.2 did not offer protection
+	    against this issue.</p>
