  script_tag(name:"insight", value:"KVM (Kernel-based Virtual Machine) is a
full virtualization solution for Linux on AMD64 and Intel 64 systems. The
qemu-kvm 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)

Red Hat would like to thank Donghai Zhu of Alibaba for reporting this
issue.

All qemu-kvm users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing this
update, shut down all running virtual machines. Once all virtual machines
have shut down, start them again for this update to take effect.");
