QEMU is vulnerable to denial of service. The Quick Emulator (QEMU) built with the Network Block Device (NBD) Server support is vulnerable to a crash via a SIGPIPE signal. The crash can occur if a client aborts a connection due to any failure during negotiation or read operation. A remote user/process could use this flaw to crash the qemu-nbd server resulting in a Denial of Service (DoS).
