QEMU (aka Quick Emulator) built to use 'address_space_translate' to map an address to a MemoryRegionSection is vulnerable to an OOB r/w access issue. It could occur while doing pci_dma_read/write calls. Affects QEMU versions > 1.6.0 and < 2.3.1. A privileged user inside guest could use this flaw to crash the guest instance resulting in DoS.
