"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2017-1305:01 advisory.

    KVM (for Kernel-based Virtual Machine) is a full virtualization solution
    for Linux on x86 hardware.
    Using KVM, one can run multiple virtual machines running unmodified Linux
    or Windows images. Each virtual machine has private virtualized hardware:
    a network card, disk, graphics adapter, etc.
    Security issues fixed with this release:
    CVE-2016-2857
    The net_checksum_calculate function in net/checksum.c in QEMU allows
    local guest OS users to cause a denial of service (out-of-bounds heap
    read and crash) via the payload length in a crafted packet.
    CVE-2017-2615
    ** 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.
    Fixed bugs:
    * Previously, rebooting a guest virtual machine more than 128 times in a short period of time caused the
    guest to shut down instead of rebooting, because the virtqueue was not cleaned properly. This update
    ensures that the virtqueue is cleaned more reliably, which prevents the described problem from occurring.

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

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