QEMU 1.7.1

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.

The (1) BMDMA and (2) AHCI HBA interfaces in the IDE functionality in QEMU 1.0 through 2.1.3 have multiple interpretations of a function's return value, which allows guest OS users to cause a host OS denial of service (memory consumption or infinite loop, and system crash) via a PRDT with zero complete sectors, related to the bmdma_prepare_buf and ahci_dma_prepare_buf functions.

Integer overflow in the virtio_net_handle_mac function in hw/net/virtio-net.c in QEMU 2.0 and earlier allows local guest users to execute arbitrary code via a MAC addresses table update request, which triggers a heap-based buffer overflow.

The virtio_load function in virtio/virtio.c in QEMU 1.x before 1.7.2 allows remote attackers to execute arbitrary code via a crafted savevm image, which triggers an out-of-bounds write.

The virtio_net_load function in hw/net/virtio-net.c in QEMU 1.5.0 through 1.7.x before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors in which the value of curr_queues is greater than max_queues, which triggers an out-of-bounds write.
