Red Hat Security Advisory 2017-2392-01
Posted Aug 2, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-2392-01 - KVM 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. The following packages have been upgraded to a later upstream version: qemu-kvm-rhev. Security Fix: A stack buffer overflow flaw was found in the Quick Emulator built with the Network Block Device client support. The flaw could occur while processing server's response to a 'NBD_OPT_LIST' request. A malicious NBD server could use this issue to crash a remote NBD client resulting in DoS or potentially execute arbitrary code on client host with privileges of the QEMU process.

Red Hat Security Advisory 2017-1856-01 - Kernel-based Virtual Machine is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm package provides the user-space component for running virtual machines that use KVM. Security Fix: An out-of-bounds memory access issue was found in Quick Emulator in the VNC display driver. This flaw could occur while refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A user inside a guest could use this flaw to crash the QEMU process.
