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-2016-7995 Qemu: usb: hcd-ehci: memory leak in ehci_process_itd
Qemu emulator(Qemu) built with the USB EHCI emulation support is vulnerable
to a memory leakage flaw. It could occur while processing isochronous transfer
descriptors(iTD), with buffer page select(PG) index that falls beyond buffer
page array area.
A privileged user inside guest could use this flaw to leak Qemu memory bytes
leading to a DoS on the host.
