Red Hat Security Advisory 2014-0888-01 - 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. 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.

The qemu-kvm packages provide a user-space component to run virtual machines using KVM. An out-of-bounds memory access flaw was found in the way QEMU's IDE device driver handled the execution of SMART EXECUTE OFFLINE commands. A privileged guest user could use this flaw 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.

Ubuntu Security Notice 2182-1 - Michael S. Tsirkin discovered that QEMU incorrectly handled vmxnet3 devices. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. This issue only applied to Ubuntu 13.10 and Ubuntu 14.04 LTS. Michael S. Tsirkin discovered that QEMU incorrectly handled virtio-net MAC addresses. A local guest could possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host. Various other issues were also addressed.
