+	  <p>PCRE library is prone to a vulnerability which leads to Heap
+	    Overflow. During subpattern calculation of a malformed regular
+	    expression, an offset that is used as an array index is fully
+	    controlled and can be large enough so that unexpected heap
+	    memory regions are accessed.</p>
+	  <p>One could at least exploit this issue to read objects nearby of
+	    the affected application's memory.</p>
+	  <p>Such information disclosure may also be used to bypass memory
+	    protection method such as ASLR.</p>
