"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2017:2408 advisory.
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 that 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)
* An information-exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR)
optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user
inside a guest could use this issue to read portions of the host memory. (CVE-2016-4020)
* A memory-leak flaw was found in the Quick Emulator (QEMU) built with USB xHCI controller emulation
support. The flaw could occur while doing a USB-device unplug operation. Unplugging the device repeatedly
resulted in leaking host memory, which affected other services on the host. A privileged user inside the
guest could exploit this flaw to cause a denial of service on the host or potentially crash the host's
QEMU process instance. (CVE-2016-7466)
* Multiple CVEs were fixed as a result of rebase to QEMU 2.9.0. (CVE-2016-6888, CVE-2016-7422,
