How to fix?

Upgrade Ubuntu:18.04 perl to version 5.26.1-6ubuntu0.5 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:18.04 relevant fixed versions and status.

regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.
