"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).

This update was imported from the SUSE:SLE-15:Update update project.");
