PCRE before 8.36 mishandles the /(((a\2)|(a*)\g<-1>))*/ pattern and related
patterns with certain internal recursive back references, which allows
remote attackers to cause a denial of service (segmentation fault) or
possibly have unspecified other impact via a crafted regular expression, as
demonstrated by a JavaScript RegExp object encountered by Konqueror.

Notes

sbeattie	mongodb package uses system pcre since 2.0.0
tyhicks	Issue affects PCRE3 only Marking ‘low’ since it requires PCRE to operate on untrusted regular expressions which is not very likely
