CVSS: 7.5EPSS: 3%CPEs: 25EXPL: 0CVE-2017-10664 – Qemu: qemu-nbd: server breaks with SIGPIPE upon client abort
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 •

The dhcp_decode function in slirp/bootp.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) via a crafted DHCP options string. La función dhcp_decode en el archivo slirp/bootp.c en QEMU (conocido como Quick Emulator), permite a los usuarios de sistemas operativos invitados locales causar una denegación de servicio (lectura fuera de límites y bloqueo del proceso QEMU) por medio de una cadena de opciones DHCP creada. • http://www.debian.org/security/2017/dsa-3925 http://www.openwall.com/lists/oss-security/2017/07/19/2 http://www.securityfocus.com/bid/99923 https://bugzilla.redhat.com/show_bug.cgi?id=1472611 https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https://lists.gnu.org/archive/html/qemu-devel/2017-07/msg05001.html • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 4%CPEs: 2EXPL: 0CVE-2017-9524 – Qemu: nbd: segmentation fault due to client non-negotiation
https://notcve.org/view.php?id=CVE-2017-9524
The qemu-nbd server in QEMU (aka Quick Emulator), when built with the Network Block Device (NBD) Server support, allows remote attackers to cause a denial of service (segmentation fault and server crash) by leveraging failure to ensure that all initialization occurs before talking to a client in the nbd_negotiate function. El servidor qemu-nbd en QEMU (también se conoce como Quick Emulator), cuando se ensambló con el soporte del servidor Network Block Device (NBD), permite a los atacantes remotos causar una denegación de servicio (fallo de segmentación y fallo del servidor) aprovechando el fallo para garantizar que toda la inicialización ocurre antes de hablar con un cliente en la función nbd_negotiate. Quick Emulator (QEMU) built with Network Block Device (NBD) Server support was vulnerable to a null-pointer dereference issue. The flaw could occur when releasing a client that was not initialized due to failed negotiation. A remote user or process could exploit this flaw to crash the qemu-nbd server (denial of service). • http://www.debian.org/security/2017/dsa-3925 http://www.openwall.com/lists/oss-security/2017/06/12/1 http://www.securityfocus.com/bid/99011 https://access.redhat.com/errata/RHSA-2017:1681 https://access.redhat.com/errata/RHSA-2017:1682 https://access.redhat.com/errata/RHSA-2017:2408 https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg06240.html https://lists.gnu.org/archive/html/qemu-devel/2017-06/msg02321.html https://access.redhat.com/security/cve/CVE&# • CWE-20: Improper Input Validation CWE-476: NULL Pointer Dereference •
