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 (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-2013-4151, CVE-2013-4535, CVE-2013-4536, CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182, CVE-2014-3461)
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.
(CVE-2014-2894)
This update also fixes the following bugs :
Can’t assign device inside non-zero PCI segment as this KVM module doesn’t support it.
This update fixes this issue and guests using the aforementioned configuration no longer fail to start.
After installing this update, shut down all running virtual machines.
Once all virtual machines have shut down, start them again for this update to take effect.

This update also fixes the following bugs :
- Previously, under certain circumstances, libvirt failed
to start guests which used a non-zero PCI domain and
SR-IOV Virtual Functions (VFs), and returned the
following error message :
Can't assign device inside non-zero PCI segment as this KVM module
doesn't support it.
This update fixes this issue and guests using the aforementioned
configuration no longer fail to start.
- Due to an incorrect initialization of the cpus_sts
bitmap, which holds the enablement status of a vCPU,
libvirt could fail to start a guest with an unusual vCPU
topology (for example, a guest with three cores and two
sockets). With this update, the initialization of
cpus_sts has been corrected, and libvirt no longer fails
to start the aforementioned guests.
After installing this update, shut down all running virtual machines.
Once all virtual machines have shut down, start them again for this
update to take effect."
