Descriptions

qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt.

qemu-nbd en QEMU (Quick Emulator) no ignora la señal SIGPIPE, lo que permite a atacantes remotos provocar una denegación de servicio desconectando el proceso durante un intento de respuesta de servidor a cliente.

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).
