https://notcve.org/view.php?id=CVE-2017-10664
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). • http://www.debian.org/security/2017/dsa-3920 http://www.openwall.com/lists/oss-security/2017/06/29/1 http://www.securityfocus.com/bid/99513 https://access.redhat.com/errata/RHSA-2017:2390 https://access.redhat.com/errata/RHSA-2017:2445 https://access.redhat.com/errata/RHSA-2017:3466 https://access.redhat.com/errata/RHSA-2017:3470 https://access.redhat.com/errata/RHSA-2017:3471 https://access.redhat.com/errata/RHSA-2017:3472 https://access.redhat.com/errata/RH • CWE-248: Uncaught Exception •
