    Updated libvirt packages fix security vulnerability:
    
    A flaw was found in the way the libvirtd daemon issued the 'suspend'
    command to a QEMU guest-agent running inside a guest, where it holds
    a monitor job while issuing the 'suspend' command to a guest-agent.
    A malicious guest-agent may use this flaw to block the libvirt daemon
    indefinitely, resulting in a denial of service (CVE-2019-20485).
