Subject: CVE-2019-8934 QEMU: ppc64: sPAPR emulator leaks the host hardware


It was found that the KVM PPC64 emulator for the sPAPR machine leaks the host 
hardware identity to all running guests. The sPAPAR(hw/ppc/spapr.c) emulator 
populates the device tree for the guest with two fields "host-serial" and 
"host-model". The values for these fields are taken via hypervisor from the 
host device tree data exposed in "/proc/device-tree/system-id" and 
"/proc/device-tree/model" file respectively.
