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.
