RHSA-2014:0927: qemu-kvm security and bug fix update (Moderate)

oval:org.mitre.oval:def:25091

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm 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 alter the QEMU disk image files loaded by a guest 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. (CVE-2014-0222 CVE-2014-0223) Multiple buffer overflow input validation and out-of-bounds write flaws were found in the way virtio virtio-net virtio-scsi usb and hpet drivers of QEMU handled state loading after migration. A user able to alter the savevm data (either on the disk or over the wire during migration) could use either of these flaws to corrupt QEMU process memory on the (destination) host which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2013-4148 CVE-2013-4149 CVE-2013-4150 CVE-2013-4151 CVE-2013-4527 CVE-2013-4529 CVE-2013-4535 CVE-2013-4536 CVE-2013-4541 CVE-2013-4542 CVE-2013-6399 CVE-2014-0182 CVE-2014-3461) These issues were discovered by Michael S.
