Description Volkan 2017-05-04 18:43:55 UTC 
Quick Emulator(Qemu) built with the keyboard input event handlers support is
vulnerable to a host memory leakage issue. It could occur if a guest user was
to generate large keyboard events, faster than Qemu could process them.

A privileged user inside guest could use this flaw to exhaust host memory,
resulting in DoS.
