CVE-2016-10028 [MEDIUM] QEMU vulnerabilities
Title: QEMU vulnerabilities
Summary: Several security issues were fixed in QEMU.
Zhenhao Hong discovered that QEMU incorrectly handled the Virtio GPU
device. An attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. This issue only affected Ubuntu
16.04 LTS and Ubuntu 16.10. (CVE-2016-10028, CVE-2016-10029)
Li Qiang discovered that QEMU incorrectly handled the 6300esb watchdog. A
privileged attacker inside the guest could use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2016-10155)
Li Qiang discovered that QEMU incorrectly handled the i.MX Fast Ethernet
Controller. A privileged attacker inside the guest could use this issue to
cause QEMU to crash, resulting in a denial of service. This issue only

CVE-2016-9913 CVE-2016-9914 CVE-2016-9915 CVE-2016-9916 Qemu: 9pfs: memory leakage via proxy/handle callbacks
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 via its '9p-handle' or '9p-proxy' backend drivers as they do not free
their respective allocated data objects.
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.
