The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2724-1 advisory.

    It was discovered that QEMU incorrectly handled a PRDT with zero complete sectors in the IDE     functionality. A malicious guest could possibly use this issue to cause a denial of service. This issue     only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-9718)

    Donghai Zhu discovered that QEMU incorrectly handled the RTL8139 driver. A malicious guest could possibly     use this issue to read sensitive information from arbitrary host memory. (CVE-2015-5165)

    Donghai Zhu discovered that QEMU incorrectly handled unplugging emulated block devices. A malicious guest     could use this issue to cause a denial of service, or possibly execute arbitrary code on the host as the     user running the QEMU process. In the default installation, when QEMU is used with libvirt, attackers     would be isolated by the libvirt AppArmor profile. This issue only affected Ubuntu 15.04. (CVE-2015-5166)

    Qinghao Tang and Mr. Zuozhi discovered that QEMU incorrectly handled memory in the VNC display driver. A     malicious guest could use this issue to cause a denial of service, or possibly execute arbitrary code on     the host as the user running the QEMU process. In the default installation, when QEMU is used with     libvirt, attackers would be isolated by the libvirt AppArmor profile. This issue only affected Ubuntu     15.04. (CVE-2015-5225)

    It was discovered that QEMU incorrectly handled the virtio-serial device. A malicious guest could use this     issue to cause a denial of service, or possibly execute arbitrary code on the host as the user running the     QEMU process. In the default installation, when QEMU is used with libvirt, attackers would be isolated by     the libvirt AppArmor profile. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.04. (CVE-2015-5745)

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