rh#1340924

Quick Emulator(Qemu) built with the Block driver for iSCSI images support
(virtio-blk) is vulnerable to a heap buffer overflow flaw. It could occur
while processing iSCSI asynchronous I/O ioctl(2) calls.

A user inside guest could use this flaw to crash the Qemu process resulting
in DoS OR potentially leverage it to execute arbitrary code with privileges
of the Qemu process on the host.
