+++ This bug was initially created as a clone of Bug #964413 +++

rh#1301643

Qemu emulator built with the USB EHCI emulation support is vulnerable to a null pointer dereference flaw. It could occur when an application attempts to write to EHCI capabilities registers.

A privileged user inside quest could use this flaw to crash the Qemu process instance resulting in DoS.
