"The remote NewStart CGSL host, running version MAIN 4.06, has libvirt packages installed that are affected by a
vulnerability:

  - It was discovered that libvirtd before versions 4.10.1
    and 5.4.1 would permit read-only clients to use the
    virDomainSaveImageGetXMLDesc() API, specifying an
    arbitrary path which would be accessed with the
    permissions of the libvirtd process. An attacker with
    access to the libvirtd socket could use this to probe
    the existence of arbitrary files, cause denial of
    service or cause libvirtd to execute arbitrary programs.
    (CVE-2019-10161)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
