3. Description:
PCRE is a Perl-compatible regular expression library.
Security Fix(es):
* Multiple flaws were found in the way PCRE handled malformed regular
expressions. An attacker able to make an application using PCRE process a
specially crafted regular expression could use these flaws to cause the
application to crash or, possibly, execute arbitrary code. (CVE-2015-8385,
