'REPORT LUNS' command when more than 256 LUNs were specified for a
single SCSI target. 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-2013-4344)

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."
