CVE-2015-8391 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:17.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pcre2 package and not the pcre2 package as distributed by Ubuntu.
The pcre_compile function in pcre_compile.c in PCRE before 8.38 mishandles certain [: nesting, which allows remote attackers to cause a denial of service (CPU consumption) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
