Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An update for qemu-kvm-rhev is now available for RHEV 3.X Hypervisor
and Agents for RHEL-7 and RHEV 4.X RHEV-H and Agents for RHEL-7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. 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) :

* An assertion-failure flaw was found in the Network Block Device
(NBD) server's initial connection negotiation, where the I/O
co-routine was undefined. This could crash the qemu-nbd server if a
client sent unexpected data during connection negotiation. A remote
user or process could use this flaw to crash the qemu-nbd server
resulting in denial of service. (CVE-2017-7539)
