Subject: CVE-2017-10664 Qemu: qemu-nbd: server breaks with SIGPIPE upon client

Hello,
Quick Emulator(Qemu) built with the Network Block Device(NBD) Server support
is vulnerable to a crash via SIGPIPE signal. It could occur if a client aborts
connection due to any failure during negotiation.
A remote user/process could use this flaw to crash the qemu-nbd server
resulting in DoS.
