Venustech ADLAB reports:

+
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.
+
Latest version of PCRE is prone to a Heap Overflow vulnerability + which could caused by the following regular expression.
