"The remote Red Hat host is missing one or more security updates for qemu-kvm-rhev.");
  script_set_attribute(attribute:"description", value:
"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2017:2408 advisory.

    KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on a variety of
    architectures. The qemu-kvm-rhev packages provide the user-space component for running virtual machines
    that use KVM in environments managed by Red Hat products.

    Security Fix(es):

    * Quick Emulator (QEMU) built with Network Block Device (NBD) Server support was vulnerable to a null-
    pointer dereference issue. The flaw could occur when releasing a client that was not initialized due to
    failed negotiation. A remote user or process could exploit this flaw to crash the qemu-nbd server (denial
    of service). (CVE-2017-9524)

    * An information-exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR)
    optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user
    inside a guest could use this issue to read portions of the host memory. (CVE-2016-4020)

    * A memory-leak flaw was found in the Quick Emulator (QEMU) built with USB xHCI controller emulation
    support. The flaw could occur while doing a USB-device unplug operation. Unplugging the device repeatedly
    resulted in leaking host memory, which affected other services on the host. A privileged user inside the
    guest could exploit this flaw to cause a denial of service on the host or potentially crash the host's
    QEMU process instance. (CVE-2016-7466)

    * Multiple CVEs were fixed as a result of rebase to QEMU 2.9.0. (CVE-2016-6888, CVE-2016-7422,
    CVE-2016-8576, CVE-2016-8669, CVE-2016-8909, CVE-2016-8910, CVE-2016-9907, CVE-2016-9911, CVE-2016-9921,
