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-2016-9102 Qemu: 9pfs: memory leakage when creating extended attribute
Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9
File System(9pfs) support, is vulnerable to memory leakage issue. It could
occur while creating extended attribute via 'Txattrcreate' message.
A privileged user inside guest could use this flaw to leak host memory,
thus affecting other services on the host and/or potentially crash the Qemu
process on the host.
