Subject: CVE-2017-10806 Qemu: usb-redirect: stack buffer overflow in debug
 logging

   Hello,

Quick emulator(Qemu) built with the USB redirector support is vulnerable to a 
stack buffer overflow flaw. It could occur while logging debug messages when 
the debug mode is enabled in the device.

A user/process could use this flaw to crash the Qemu process on the host 
resulting in DoS.
