==============================================
  Hello,

Quick Emulator(Qemu) built with the Network Block Device(NBD) client support is
vulnerable to a stack buffer overflow issue. It could occur while processing
server's response to a 'NBD_OPT_LIST' request.


A malicious NBD server could use this issue to crash remote NBD client
resulting in DoS or potentially execute arbitrary code on client host with
privileges of the Qemu process.
