"According to the versions of the libvirt packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - libvirt: arbitrary file read/exec via

  - libvirt: virDomainManagedSaveDefineXML API exposed to
    readonly clients (CVE-2019-10166)

  - libvirt: arbitrary command execution via
    virConnectGetDomainCapabilities API (CVE-2019-10167)

  - libvirt: arbitrary command execution via
    virConnectBaselineHypervisorCPU and
    virConnectCompareHypervisorCPU APIs (CVE-2019-10168)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
