The qemu-nbd server in QEMU (aka Quick Emulator), when built with the
Network Block Device (NBD) Server support, allows remote attackers to cause
a denial of service (segmentation fault and server crash) by leveraging
failure to ensure that all initialization occurs before talking to a client
in the nbd_negotiate function.
