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