"The version of QEMU installed on the remote Windows host is prior to 8.2.1 and therefore vulnerable to the following:
A flaw was found in QEMU, in the virtio-scsi, virtio-blk, and virtio-crypto devices. The size for virtqueue_push 
as set in virtio_scsi_complete_req / virtio_blk_req_complete / virito_crypto_req_complete could be larger than the 
true size of the data which has been sent to guest. Once virtqueue_push() finally calls dma_memory_unmap to ummap 
the in_iov, it may call the address_space_write function to write back the data. Some uninitialized data may exist 
in the bounce.buffer, leading to an information leak. 

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version 
number.");
