Description

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.
