Red Hat Security Advisory 2016-1653-01 – KVM is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM in environments managed by Red Hat Enterprise Virtualization Manager. Security Fix: Quick Emulator built with the Block driver for iSCSI images support is vulnerable to a heap buffer overflow issue. It could occur while processing iSCSI asynchronous I/O ioctl calls. A user inside guest could use this flaw to crash the Qemu process resulting in DoS or potentially leverage it to execute arbitrary code with privileges of the Qemu process on the host.
