Description Prasad J Pandit 2014-08-22 12:42:35 UTC
An out of bounds memory access flaw was found in Qemu's ACPI PCI hotplug
interface. It leads to Qemu's memory corruption via OOB write(4 bytes) and 
information disclosure(~12 bytes) through OOB read.

A user with a custom PCI device could use this flaw to leak qemu process'
memory bytes or corrupt them on the host.
