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.

Multiple issues in Libxml2 (2.9.2 - 2.9.5)
Libxml2 is the XML C parser and toolkit developed for the Gnome project. Due to its flexible C implementation and continuous development, Libxml2 is known to be very portable, the library builds and works on a variety of systems (Linux, Unix, Windows, CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, VxWorks, ...). It is or has been adopted by many major vendors or products including Google (Chrome), VMWare, Apple (Safari, Mac OSX, iOS, ...), and many embedded systems. As in the [Google Patch Rewards](https://www.google.com.sg/about/appsecurity/patch-rewards) , Libxml2 is listed in the category of core infrastructure data parsers.
From 2015-2016, our fuzzing work on Libxml2 has systematically identified a sequence of bugs including use-after

CVE-2016-7116 Qemu: 9p: directory traversal flaw in 9p virtio backend
Quick Emulator(Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to a directory/path traversal issue. It could occur while creating or accessing files on a shared host directory.
A privileged user inside guest could use this flaw to access undue files on the host.
