libvirt <= 1.2.8 is suffering from an out-of-bounds read access [0] in qemuDomainGetBlockIoTune() due to invalid index.

A remote attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd or, potentially, leak memory from the libvirtd process.

A fix for this flaw has been commited upstream [1] and f.e. already applied by debian [2] as 1.2.9 is not yet there.

This task depends upon
