<blockquote cite="https://bugs.exim.org/show_bug.cgi?id=1667">
<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>
<p>/(?J:(?|(:(?|(?'R')(\k'R')|((?'R')))H'Rk'Rf)|s(?'R'))))/</p>
