How to fix?

Upgrade Ubuntu:14.04 perl to version 5.18.2-2ubuntu1.7+esm3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perl package and not the perl package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.
