+	  <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().
+	    The Heap Overflow vulnerability is caused by the following regular
+	    expression.</p>
+	    <p>/(?J:(?|(:(?|(?'R')(\z(?|(?'R')(\k'R')|((?'R')))k'R')|((?'R')))H'Ak'Rf)|s(?'R')))/</p>
+	    <p>A dry run of this particular regular expression with pcretest will
+	    reports "double free or corruption (!prev)".
+	    But it is actually a heap overflow problem.
+	    The overflow only affects pcre 8.x branch, pcre2 branch is not affected.</p>
