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

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)

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.");
