The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2016:0082 :
Updated qemu-kvm packages that fix one security issue are now
available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having Important
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.
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.
Red Hat would like to thank Donghai Zhu of Alibaba for reporting this
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.
