"The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2016-880:04 advisory.

    Libvirt is a C toolkit to interact with the virtualization capabilities
    of recent versions of Linux (and other OSes). The main package includes
    the libvirtd server exporting the virtualization support.
    Security issues fixed with this release:
    CVE-2015-5160
    ** RESERVED **
    This candidate has been reserved by an organization or individual that
    will use it when announcing a new security problem.  When the
    candidate has been publicized, the details for this candidate will be
    provided.
    CVE-2015-5313
    Directory traversal vulnerability in the
    virStorageBackendFileSystemVolCreate function in
    storage/storage_backend_fs.c in libvirt, when fine-grained Access
    Control Lists (ACL) are in effect, allows local users with
    storage_vol:create ACL but not domain:write permission to write to
    arbitrary files via a .. (dot dot) in a volume name.
    CVE-2016-5008
    libvirt before 2.0.0 improperly disables password checking when the
    password on a VNC server is set to an empty string, which allows
    remote attackers to bypass authentication and establish a VNC session
    by connecting to the server.
    The following packages have been upgraded to a newer upstream version: libvirt (2.0.0).
    Additional Changes:

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.
