Heap-based buffer overflow in the process_tx_desc function in the e1000 emulation (hw/e1000.c) in qemu-kvm 0.12, and possibly other versions, allows guest OS users to cause a denial of service (QEMU crash) and possibly execute arbitrary code via crafted legacy mode packets.

The virtio_queue_notify in qemu-kvm 0.14.0 and earlier does not properly validate the virtqueue number, which allows guest users to cause a denial of service (guest crash) and possibly execute arbitrary code via a negative number in the Queue Notify field of the Virtio Header, which bypasses a signed comparison.
