"This update for cronie fixes the following issues :

Security issues fixed :

CVE-2019-9704: Fixed an insufficient check in the return value of
calloc which could allow a local user to create Denial of Service by
crashing the daemon (bsc#1128937).

CVE-2019-9705: Fixed an implementation vulnerability which could allow
a local user to exhaust the memory resulting in Denial of Service
(bsc#1128935).

Bug fixes: Manual start of cron is possible even when it's already
started using systemd (bsc#1133100).

Cron schedules only one job of crontab (bsc#1130746).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
