The qemuDomainGetBlockIoTune function in qemu/qemu_driver.c in libvirt
before 1.2.9, when a disk has been hot-plugged or removed from the live
image, allows remote attackers to cause a denial of service (crash) or read
sensitive heap information via a crafted blkiotune query, which triggers an
out-of-bounds read.
