The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1508 advisory.

    KVM (Kernel-based Virtual Machine) is a full virtualization solution for     Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the     user-space component for running virtual machines using KVM.

    A heap buffer overflow flaw was found in the way QEMU's IDE subsystem     handled I/O buffer access while processing certain ATAPI commands.
    A privileged guest user in a guest with the CDROM drive enabled could     potentially use this flaw to execute arbitrary code on the host with the     privileges of the host's QEMU process corresponding to the guest.
    (CVE-2015-5154)

    An out-of-bounds memory access flaw, leading to memory corruption or     possibly an information leak, was found in QEMU's pit_ioport_read()     function. A privileged guest user in a QEMU guest, which had QEMU PIT     emulation enabled, could potentially, in rare cases, use this flaw to     execute arbitrary code on the host with the privileges of the hosting QEMU     process. (CVE-2015-3214)

    Red Hat would like to thank Matt Tait of Google's Project Zero security     team for reporting the CVE-2015-3214 issue. The CVE-2015-5154 issue was     discovered by Kevin Wolf of Red Hat.

    All qemu-kvm-rhev users are advised to upgrade to these updated packages,     which contain a backported patch to correct this issue. After installing     this update, shut down all running virtual machines. Once all virtual     machines have shut down, start them again for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
