NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-driver-storage package and not the libvirt-daemon-driver-storage package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

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.
