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 •

Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation. Desbordamiento de búfer basado en memoria dinámica (heap) en Cirrus CLGD 54xx VGA Emulator en Quick Emulator (Qemu) en versiones 2.8 y anteriores permite que los usuarios invitados del sistema operativo ejecuten código arbitrario o provoquen una denegación de servicio (DoS) mediante vectores relacionados con un cliente VNC que actualiza su display después de una operación VGA. An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data via various bitblt functions.
