Red Hat Security Advisory 2014-1941-01 - 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 Linux OpenStack Platform. An information leak flaw was found in the way QEMU's VGA emulator accessed frame buffer memory for high resolution displays. A privileged guest user could use this flaw to leak memory contents of the host to the guest by setting the display to use a high resolution in the guest. This issue was discovered by Laszlo Ersek of Red Hat.
