How to fix?

Upgrade Ubuntu:16.04 pcre3 to version 2:8.38-3.1ubuntu0.1~esm2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pcre3 package and not the pcre3 package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

The compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE through 8.x before revision 1680 (e.g., the PHP 7.1.1 bundled version) allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted regular expression.
