The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3575-1 advisory.

    It was discovered that QEMU incorrectly handled guest ram. A privileged 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 16.04 LTS. (CVE-2017-11334)

    David Buchanan discovered that QEMU incorrectly handled the VGA device. A privileged attacker inside the     guest could use this issue to cause QEMU to crash, resulting in a denial of service. This issue was only     addressed in Ubuntu 17.10. (CVE-2017-13672)

    Thomas Garnier discovered that QEMU incorrectly handled multiboot. An attacker 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 affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-14167)

    Tuomas Tynkkynen discovered that QEMU incorrectly handled VirtFS directory sharing. An attacker could use     this issue to obtain sensitive information from host memory. (CVE-2017-15038)

    Eric Blake discovered that QEMU incorrectly handled memory in the NBD server. An attacker could use this     issue to cause the NBD server to crash, resulting in a denial of service. This issue only affected Ubuntu     17.10. (CVE-2017-15118)

    Eric Blake discovered that QEMU incorrectly handled certain options to the NBD server. An attacker could     use this issue to cause the NBD server to crash, resulting in a denial of service. This issue only     affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-15119)

    Daniel Berrange discovered that QEMU incorrectly handled the VNC server. A remote attacker could possibly     use this issue to consume memory, resulting in a denial of service. This issue was only addressed in     Ubuntu 17.10. (CVE-2017-15124)

    Carl Brassey discovered that QEMU incorrectly handled certain websockets. A remote attacker could possibly     use this issue to consume memory, resulting in a denial of service. This issue only affected Ubuntu 17.10.
    (CVE-2017-15268)

    Guoxiang Niu discovered that QEMU incorrectly handled the Cirrus VGA device. A privileged attacker inside     the guest could use this issue to cause QEMU to crash, resulting in a denial of service. (CVE-2017-15289)

    Cyrille Chatras discovered that QEMU incorrectly handled certain PS2 values during migration. An attacker     could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly     execute arbitrary code. This issue only affected Ubuntu 16.04 LTS and Ubuntu 17.10. (CVE-2017-16845)

    It was discovered that QEMU incorrectly handled the Virtio Vring implementation. An attacker could     possibly use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected     Ubuntu 16.04 LTS and Ubuntu 17.10. (CVE-2017-17381)

    Eric Blake discovered that QEMU incorrectly handled certain rounding operations. An attacker could     possibly use this issue to cause QEMU to crash, resulting in a denial of service. This issue only affected     Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-18043)

    Jiang Xin and Lin ZheCheng discovered that QEMU incorrectly handled the VGA device. A privileged attacker     inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service.
    (CVE-2018-5683)
