Subject: CVE-2017-9374 Qemu: usb: ehci host memory leakage during hotunplug
Hello,
Quick Emulator(Qemu) built with the USB EHCI Emulation support is vulnerable
to a memory leakage issue. It could occur while hot-unplugging 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.
