The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201612-10
(libvirt: Directory traversal)
Normally, only privileged users can coerce libvirt into creating or
opening existing files using the virStorageVol APIs; and such users
already have full privilege to create any domain XML.
But in the case of fine-grained ACLs, it is feasible that a user can be
granted storage_vol:create but not domain:write, and it violates
assumptions if such a user can abuse libvirt to access files outside of
the storage pool.
When fine-grained Access Control Lists (ACL) are in effect, an
authenticated local user with storage_vol:create permission but without
domain:write permission maybe able to create or access arbitrary files
outside of the storage pool.
Don’t make use of fine-grained Access Control Lists (ACL) in libvirt;
In Gentoo, libvirt’s ACL support is disable by default unless you
enable the “policykit” USE flag.

All libvirt users should upgrade to the latest version:
