Description Prasad J Pandit 2017-06-06 07:57:44 EDT
Quick Emulator(Qemu) built with the USB EHCI Emulation support is vulnerable
to a memory leakage issue. It could occur while hotunplugging the device, as
it does not release the memory allocated at initialisation.

A guest user/process could use this issue to leak host memory, resulting in
DoS for host.
