Ubuntu priority

Low

Why this priority?

Description

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.

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
