Description Victor Pereira 2016-09-22 07:20:08 UTC
rh#1377837

Quick Emulator(Qemu) built with the USB xHCI controller emulation support is
vulnerable to a memory leakage issue. It could occur while doing a USB device
unplug operation; Doing so repeatedly would result in leaking host memory,
affecting other services on the host.

A privileged user inside guest could use this flaw to cause a DoS on the host
and/or potentially crash the Qemu process instance on the host.
