The remote Red Hat host is missing one or more security updates.
An update for qemu-kvm-rhev is now available for RHEV 3.X Hypervisor
and Agents for RHEL-6.
Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
KVM (Kernel-based Virtual Machine) is a full virtualization solution
for Linux on a variety of architectures. The qemu-kvm-rhev packages
provide the user-space component for running virtual machines that use
KVM in environments managed by Red Hat products.
Security Fix(es) :
* Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA emulator
support is vulnerable to an out-of-bounds access issue. It could occur
while copying VGA data via bitblt copy in backward mode. A privileged
user inside a guest could use this flaw to crash the Qemu process
resulting in DoS or potentially execute arbitrary code on the host
with privileges of Qemu process on the host. (CVE-2017-2615)
* An out-of-bounds read-access flaw was found in the QEMU emulator
built with IP checksum routines. The flaw could occur when computing a
TCP/UDP packet's checksum, because a QEMU function used the packet's
payload length without checking against the data buffer's size. A user
inside a guest could use this flaw to crash the QEMU process (denial
of service). (CVE-2016-2857)
