CVSS: 7.5EPSS: 4%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 •
CVSS: 9.8EPSS: 1%CPEs: 12EXPL: 0CVE-2017-9214 – openvswitch: Integer underflow in the ofputil_pull_queue_get_config_reply10 function
https://notcve.org/view.php?id=CVE-2017-9214
In Open vSwitch (OvS) 2.7.0, while parsing an OFPT_QUEUE_GET_CONFIG_REPLY type OFP 1.0 message, there is a buffer over-read that is caused by an unsigned integer underflow in the function `ofputil_pull_queue_get_config_reply10` in `lib/ofp-util.c`. En Open vSwitch (OvS) versión 2.7.0, mientras analiza un mensaje OFPT_QUEUE_GET_CONFIG_REPLY tipo OFP versión 1.0, se presenta una lectura excesiva búfer causada por un desbordamiento de enteros sin signo en la función “ofputil_pull_queue_get_config_reply10” en la biblioteca “lib/ofp-util.c”. An unsigned integer wrap around that led to a buffer over-read was found when parsing OFPT_QUEUE_GET_CONFIG_REPLY messages in Open vSwitch (OvS). An attacker could use this issue to cause a remote denial of service attack. • https://access.redhat.com/errata/RHSA-2017:2418 https://access.redhat.com/errata/RHSA-2017:2553 https://access.redhat.com/errata/RHSA-2017:2648 https://access.redhat.com/errata/RHSA-2017:2665 https://access.redhat.com/errata/RHSA-2017:2692 https://access.redhat.com/errata/RHSA-2017:2698 https://access.redhat.com/errata/RHSA-2017:2727 https://lists.debian.org/debian-lts-announce/2021/02/msg00032.html https://mail.openvswitch.org/pipermail/ovs-dev/2017-May/332711.html https • CWE-190: Integer Overflow or Wraparound CWE-191: Integer Underflow (Wrap or Wraparound) •
CVSS: 10.0EPSS: 0%CPEs: 4EXPL: 0CVE-2017-2637 – rhosp-director: libvirtd is deployed with no authentication
https://notcve.org/view.php?id=CVE-2017-2637
A design flaw issue was found in the Red Hat OpenStack Platform director use of TripleO to enable libvirtd based live-migration. Libvirtd is deployed by default (by director) listening on 0.0.0.0 (all interfaces) with no-authentication or encryption. Anyone able to make a TCP connection to any compute host IP address, including 127.0.0.1, other loopback interface addresses, or in some cases possibly addresses that have been exposed beyond the management interface, could use this to open a virsh session to the libvirtd instance and gain control of virtual machine instances or possibly take over the host. Se ha detectado un fallo de diseño en el director de Red Hat OpenStack Platform que utiliza TripleO para permitir migraciones live basadas en libvirtd. Libvirtd se implementa por defecto (por el director) escuchando en 0.0.0.0 (todas las interfaces) sin ninguna autenticación o cifrado. • http://www.securityfocus.com/bid/98576 https://access.redhat.com/errata/RHSA-2017:1242 https://access.redhat.com/errata/RHSA-2017:1504 https://access.redhat.com/errata/RHSA-2017:1537 https://access.redhat.com/errata/RHSA-2017:1546 https://access.redhat.com/solutions/3022771 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-2637 https://wiki.openstack.org/wiki/OSSN/OSSN-0007 https://access.redhat.com/security/cve/CVE-2017-2637 https://bugzilla.redhat.com/show_bug • CWE-306: Missing Authentication for Critical Function •
