+	  <p>PCRE library is prone to a vulnerability which leads to Heap
+	    Overflow. During the compilation of a malformed regular expression,
+	    more data is written on the malloced block than the expected size
+	    output by compile_regex. Exploits with advanced Heap Fengshui
+	    techniques may allow an attacker to execute arbitrary code in the
+	    context of the user running the affected application.</p>
+	  <p>Latest version of PCRE is prone to a Heap Overflow vulnerability
+	    which could caused by the following regular expression.</p>
