CVE-2016-5403 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
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-2016-8576 Qemu: usb: xHCI: infinite loop vulnerability in xhci_ring_fetch
Quick Emulator(Qemu) built with the USB xHCI controller emulation support is vulnerable to an infinite loop issue. It could occur while processing
USB command ring in 'xhci_ring_fetch'.
A privileged user/process inside guest could use this issue to crash the Qemu process on the host leading to DoS.
