util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module. util/virlog.c en libvirt no determina correctamente el nombre de host en el arranque del contenedor LXC, lo que permite que usuarios locales invitados del sistema operativo omitan un mecanismo de protección de contenedor planeado y ejecuten comandos arbitrarios mediante un módulo NSS manipulado. • http://www.ubuntu.com/usn/USN-3576-1 https://access.redhat.com/errata/RHSA-2018:3113 https://www.debian.org/security/2018/dsa-4137 https://www.redhat.com/archives/libvir-list/2018-February/msg00239.html https://access.redhat.com/security/cve/CVE-2018-6764 https://bugzilla.redhat.com/show_bug.cgi?id=1541444 • CWE-179: Incorrect Behavior Order: Early Validation CWE-346: Origin Validation Error •

https://notcve.org/view.php?id=CVE-2015-5160
libvirt before 2.2 includes Ceph credentials on the qemu command line when using RADOS Block Device (aka RBD), which allows local users to obtain sensitive information via a process listing. libvirt en versiones anteriores a la 2.2 incluye las credenciales de Ceph en la línea de comandos qemu cuando se utiliza RADOS Block Device (también conocido como RBD), lo que permite a los usuarios locales obtener información sensible mediante un listado de procesos. It was found that the libvirt daemon, when using RBD (RADOS Block Device), leaked private credentials to the process list. A local attacker could use this flaw to perform certain privileged operations within the cluster. • http://rhn.redhat.com/errata/RHSA-2016-2577.html http://www.openwall.com/lists/oss-security/2017/07/21/3 https://bugs.launchpad.net/ossn/+bug/1686743 https://bugzilla.redhat.com/show_bug.cgi?id=1245647 https://wiki.openstack.org/wiki/OSSN/OSSN-0079 https://access.redhat.com/security/cve/CVE-2015-5160 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 9.8EPSS: 2%CPEs: 2EXPL: 0CVE-2016-5008 – libvirt: Setting empty VNC password allows access to unauthorized users
https://notcve.org/view.php?id=CVE-2016-5008
libvirt before 2.0.0 improperly disables password checking when the password on a VNC server is set to an empty string, which allows remote attackers to bypass authentication and establish a VNC session by connecting to the server. libvirt en versiones anteriores a 2.0.0 desactiva inadecuadamente la comprobación de contraseñas cuando la contraseña en un servidor VNC está establecida en una cadena vacía, lo que permite a atacantes remotos eludir la autenticación y establecer una sesióin VNC conectándose al servidor. It was found that setting a VNC password to an empty string in libvirt did not disable all access to the VNC server as documented, instead it allowed access with no authentication required. An attacker could use this flaw to access a VNC server with an empty VNC password without any authentication. • http://lists.opensuse.org/opensuse-updates/2016-07/msg00054.html http://lists.opensuse.org/opensuse-updates/2016-07/msg00055.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00024.html http://rhn.redhat.com/errata/RHSA-2016-2577.html http://security.libvirt.org/2016/0001.html http://www.debian.org/security/2016/dsa-3613 http://www.securityfocus.com/bid/91562 https://bugzilla.redhat.com/show_bug.cgi?id=1180092 https://lists.fedoraproject.org/archives/list/package-announc • CWE-284: Improper Access Control •
