CVE-2015-8382: The match function in pcre_exec.c in PCRE before
8.37 mishandles the
/(?:((abcd))|(((?:(?:(?:(?:abc|(?:abcdef))))b)abcdefghi)abc)|((*ACCEPT)))/
pattern and related patterns involving (*ACCEPT), which allows remote
attackers to obtain sensitive information from process memory or cause a
denial of service
(partially initialized memory and application crash) via a crafted
regular expression, as demonstrated by a JavaScript RegExp object
encountered by Konqueror, aka ZDI-CAN-2547.
