How to fix?

Upgrade Debian:9 cron to version 3.0pl1-128+deb9u2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cron package and not the cron package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

Vixie Cron before the 3.0pl1-133 Debian package allows local users to cause a denial of service (daemon crash) via a large crontab file because the calloc return value is not checked.
