"According to the version of the libvirt packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerability :

  - qemu/qemu_driver.c in libvirt before 6.0.0 mishandles
    the holding of a monitor job during a query to a guest
    agent, which allows attackers to cause a denial of
    service (API blockage).(CVE-2019-20485)

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