The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2891-1 advisory.

    Qinghao Tang discovered that QEMU incorrectly handled PCI MSI-X support. An attacker inside the guest     could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected     Ubuntu 14.04 LTS and Ubuntu 15.10. (CVE-2015-7549)

    Lian Yihan discovered that QEMU incorrectly handled the VNC server. A remote attacker could use this issue     to cause QEMU to crash, resulting in a denial of service. (CVE-2015-8504)

    Felix Wilhelm discovered a race condition in the Xen paravirtualized drivers which can cause double fetch     vulnerabilities. An attacker in the paravirtualized guest could exploit this flaw to cause a denial of     service (crash the host) or potentially execute arbitrary code on the host. (CVE-2015-8550)

    Qinghao Tang discovered that QEMU incorrectly handled USB EHCI emulation support. An attacker inside the     guest could use this issue to cause QEMU to consume resources, resulting in a denial of service.
    (CVE-2015-8558)

    Qinghao Tang discovered that QEMU incorrectly handled the vmxnet3 device. An attacker inside the guest     could use this issue to cause QEMU to consume resources, resulting in a denial of service. This issue only     affected Ubuntu 14.04 LTS and Ubuntu 15.10. (CVE-2015-8567, CVE-2015-8568)

    Qinghao Tang discovered that QEMU incorrectly handled SCSI MegaRAID SAS HBA emulation. An attacker inside     the guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue only     affected Ubuntu 14.04 LTS and Ubuntu 15.10. (CVE-2015-8613)

    Ling Liu discovered that QEMU incorrectly handled the Human Monitor Interface. A local attacker could use     this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04     LTS and Ubuntu 15.10. (CVE-2015-8619, CVE-2016-1922)

    David Alan Gilbert discovered that QEMU incorrectly handled the Q35 chipset emulation when performing VM     guest migrations. An attacker could use this issue to cause QEMU to crash, resulting in a denial of     service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 15.10. (CVE-2015-8666)

    Ling Liu discovered that QEMU incorrectly handled the NE2000 device. An attacker inside the guest could     use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2015-8743)

    It was discovered that QEMU incorrectly handled the vmxnet3 device. An attacker inside the guest could use     this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04     LTS and Ubuntu 15.10. (CVE-2015-8744, CVE-2015-8745)

    Qinghao Tang discovered that QEMU incorrect handled IDE AHCI emulation. An attacker inside the 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. (CVE-2016-1568)

    Donghai Zhu discovered that QEMU incorrect handled the firmware configuration device. An attacker inside     the 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. (CVE-2016-1714)

    It was discovered that QEMU incorrectly handled the e1000 device. An attacker inside the guest could use     this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2016-1981)

    Zuozhi Fzz discovered that QEMU incorrectly handled IDE AHCI emulation. An attacker inside the guest could     use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu     15.10. (CVE-2016-2197)

    Zuozhi Fzz discovered that QEMU incorrectly handled USB EHCI emulation. An attacker inside the guest could     use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected Ubuntu     14.04 LTS and Ubuntu 15.10. (CVE-2016-2198)
