Heap-based buffer overflow in the virtio_load function in hw/virtio/virtio.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a crafted config length in a savevm image.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
