"According to the version of the libvirt packages installed, the

vulnerability :

  - A NULL pointer dereference flaw was discovered in

    through the QEMU agent. An attacker in a guest VM can
    use this flaw to crash libvirtd and cause a denial of
    service.(CVE-2019-3840)

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.");
