Vulnerability Insight:
Zhenhao Hong discovered that QEMU incorrectly handled the Virtio module. A
privileged attacker inside the guest could use this issue to cause QEMU to
consume resources, resulting in a denial of service. (CVE-2016-5403)
Li Qiang discovered that QEMU incorrectly handled VMWARE VMXNET3 network
card 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 affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10.
(CVE-2016-6833, CVE-2016-6834, CVE-2016-6888)
Li Qiang discovered that QEMU incorrectly handled VMWARE VMXNET3 network
card 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 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, Ubuntu 16.04
LTS and Ubuntu 16.10. (CVE-2016-6835)
Li Qiang discovered that QEMU incorrectly handled VMWARE VMXNET3 network
card emulation support. A privileged attacker inside the guest could use
this issue to possibly to obtain sensitive host memory. This issue only
affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10.
(CVE-2016-6836)
Felix Wilhelm discovered that QEMU incorrectly handled Plan 9 File System
(9pfs) support. A privileged attacker inside the guest could use this issue

issue to cause QEMU to crash, resulting in a denial of service.
This issue only affected Ubuntu 16.10. (CVE-2016-7157)
Hu Chaojian discovered that QEMU incorrectly handled xlnx.xps-ethernetlite
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
execute arbitrary code on the host. In the default installation, when QEMU
