https://notcve.org/view.php?id=CVE-2015-8388
PCRE before 8.38 mishandles the /(?=di(?<=(?1))|(?=(.))))/ pattern and related patterns with an unmatched closing parenthesis, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror. • http://rhn.redhat.com/errata/RHSA-2016-1025.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://vcs.pcre.org/pcre/code/trunk/ChangeLog?view=markup http://www-01.ibm.com/support/docview.wss?uid=isg3T1023886 http://www.openwall.com/lists/oss-security/2015/11/29/1 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/85576 https://access.redhat.com/errata/RHSA-2016:1132 https://bto.bluecoat.com/security • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow CWE-185: Incorrect Regular Expression •
