Red Hat Security Advisory 2014-1268-01 - 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. Two integer overflow flaws were found in the QEMU block driver for QCOW version 1 disk images. A user able to supply a malicious image file to QEMU or to helper tools used in image conversion by services such as glance and nova could potentially use these flaws to cause memory corruption, resulting in a crash or possibly arbitrary code execution.

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. Multiple buffer overflow, input validation, and out-of-bounds write flaws were found in the way the virtio, virtio-net, virtio-scsi, and usb drivers of QEMU handled state loading after migration. A user able to alter the savevm data could use either of these flaws to corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process.
