The remote SUSE host is missing one or more security updates.

Description

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 deamon (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).
