The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3047-1 advisory.

    Li Qiang discovered that QEMU incorrectly handled 53C9X Fast SCSI controller emulation. A privileged     attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service,     or possibly execute arbitrary code on the host. In the default installation, when QEMU is used with     libvirt, attackers would be isolated by the libvirt AppArmor profile. This issue only applied to Ubuntu     14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-4439, CVE-2016-4441, CVE-2016-5238, CVE-2016-5338,     CVE-2016-6351)

    Li Qiang and Qinghao Tang discovered that QEMU incorrectly handled the VMWare VGA module. A privileged     attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service,     or possibly to obtain sensitive host memory. (CVE-2016-4453, CVE-2016-4454)

    Li Qiang discovered that QEMU incorrectly handled VMWARE PVSCSI paravirtual SCSI bus emulation support. A     privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of     service. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-4952)

    Li Qiang discovered that QEMU incorrectly handled MegaRAID SAS 8708EM2 Host Bus Adapter emulation support.
    A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial     of service, or possibly to obtain sensitive host memory. This issue only applied to Ubuntu 14.04 LTS and     Ubuntu 16.04 LTS. (CVE-2016-5105, CVE-2016-5106, CVE-2016-5107, CVE-2016-5337)

    It was discovered that QEMU incorrectly handled certain iSCSI asynchronous I/O ioctl calls. An attacker     inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or     possibly execute arbitrary code on the host. In the default installation, when QEMU is used with libvirt,     attackers would be isolated by the libvirt AppArmor profile. This issue only applied to Ubuntu 14.04 LTS     and Ubuntu 16.04 LTS. (CVE-2016-5126)

    Zhenhao Hong discovered that QEMU incorrectly handled the Virtio module. A privileged attacker inside the     guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-5403)

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