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-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 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 Network Block Device (NBD) Server
support was vulnerable to a NULL pointer dereference issue. The flaw
could occur when releasing a client, which was not initialized due to
failed negotiation. A remote user or process could exploit this flaw
to crash the qemu-nbd server (denial of service). (CVE-2017-9524)
Bug Fix(es) :
* Previously, when the data plane was in use, changing the target
image of a virtual SCSI CD device caused the guest to terminate
unexpectedly with a core dump. With this update, the virtio-scsi bus
rejects SCSI CDs when the data plane is active, which prevents the
crash from occurring. Note that this is a temporary solution, and a
full fix to make the data plane and SCSI CD compatible will be
provided in the future. (BZ#1461837)
