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

CVE-2016-8669 Qemu: char: divide by zero error in serial_update_parameters
Quick Emulator(Qemu) built with the 16550A UART emulation support is vulnerable
to a divide by zero issue. It could occur while updating serial device
parameters in 'serial_update_parameters'.
A privileged guest user could use this flaw to crash the Qemu process instance
on the host, resulting in DoS.
