QEMU 'pit_ioport_read()' Function Memory Corruption Vulnerability

QEMU is prone to a memory-corruption vulnerability because it fails to perform adequate boundary-checks on user-supplied data.

An attacker can exploit this issue to execute arbitrary code on the host with the privileges of the hosting QEMU process. Failed exploit attempts may result in a denial-of-service condition.
