Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the

user-space component for running virtual machines using KVM.

 

An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware

Configuration device emulation processed certain firmware configurations.

A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the

QEMU process instance or, potentially, execute arbitrary code on the host

with privileges of the QEMU process. (CVE-2016-1714)
