CVE-2013-6458

Multiple race conditions in the (1) virDomainBlockStats, (2)
virDomainGetBlockInf, (3) qemuDomainBlockJobImpl, and (4)
virDomainGetBlockIoTune functions in libvirt before 1.2.1 do not properly
verify that the disk is attached, which allows remote read-only attackers
to cause a denial of service (libvirtd crash) via the
virDomainDetachDeviceFlags command.
