How to fix?

Upgrade Ubuntu:14.04 perl to version 5.18.2-2ubuntu1.4 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.

Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers to execute arbitrary code via a large item count.
