## Description

PCRE before 8.38 mishandles the /(?J)(?'d'(?'d'\g{d}))/ pattern and related
patterns with certain recursive back references, 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, a related issue to
CVE-2015-8392 and CVE-2015-8395.

### [tyhicks](https://launchpad.net/~tyhicks)

Issue affects PCRE3 only
Marking 'low' since it requires PCRE to operate on untrusted regular
expressions which is not very likely
Per Debian, the fix for CVE-2015-3210 also fixes this issue
