Description Prasad J Pandit 2016-12-07 07:26:51 UTC
Quick Emulator(Qemu) built with the USB EHCI Emulation support is vulnerable
to a memory leakage issue. It could occur while processing packet data in
'ehci_init_transfer'.

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