The libxlDomainGetNumaParameters function in the libxl driver (libxl/libxl_driver.c) in libvirt before 1.2.1 does not properly initialize the nodemap, which allows local users to cause a denial of service (invalid free operation and crash) or possibly execute arbitrary code via an inactive domain to the virsh numatune command. La función libxlDomainGetNumaParameters en el driver libxl (libxl/libxl_driver.c) de libvirt anteriores a 1.2.1 no inicializa correctamente el nodemap, lo cual permite a usuarios locales causar denegación de servicio (operación de liberación inválida y caída) o posiblemente ejecutar código arbitrario a través de un dominio inactivo en el comando virsh numatune. • http://libvirt.org/news.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00060.html http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://www.ubuntu.com/usn/USN-2093-1 https://bugzilla.redhat.com/show_bug.cgi?id=1048629 https://www.redhat.com/archives/libvir-list/2013-December/msg01176.html https://www.redhat.com/archives/libvir-list/2013-December/msg01258.html • CWE-264: Permissions, Privileges, and Access Controls •

libvirt 1.1.1 through 1.2.0 allows context-dependent attackers to bypass the domain:getattr and connect:search_domains restrictions in ACLs and obtain sensitive domain object information via a request to the (1) virConnectDomainEventRegister and (2) virConnectDomainEventRegisterAny functions in the event registration API. libvirt 1.1.1 a 1.2.0 permite a atacantes dependientes del contexto sortear restricciones domain:getattr y connecdt:search_domains en ACLs y obtener información sensible de objetos a través de una petición a funciones (1) virConnectDomainEventRegister y (2) virConnectDomainEventRegisterAny en la API de registro de eventos. • http://libvirt.org/news.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00060.html http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://www.ubuntu.com/usn/USN-2093-1 https://bugzilla.redhat.com/show_bug.cgi?id=1048637 https://www.redhat.com/archives/libvir-list/2014-January/msg00684.html • CWE-264: Permissions, Privileges, and Access Controls •

Multiple race conditions in the (1) virDomainBlockStats, (2) virDomainGetBlockInf, (3) qemuDomainBlockJobImpl, and (4) virDomainGetBlockIoTune functions in libvirt before 1.2.1 do not properly verify that the disk is attached, which allows remote read-only attackers to cause a denial of service (libvirtd crash) via the virDomainDetachDeviceFlags command. Múltiples condiciones de carrera en las funciones (1) virDomainBlockStats, (2) virDomainGetBlockInf, (3) qemuDomainBlockJobImpl y (4) virDomainGetBlockIoTune en libvirt anteriores a 1.2.1 no verifica correctamente que el disco esté conectado, lo cual permite a atacantes remotos con permisos de sólo lectura causar denegación de servicio (caída de libvirtd) a través del comando virDomainDetachDeviceFlags. • http://libvirt.org/news.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00060.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00062.html http://rhn.redhat.com/errata/RHSA-2014-0103.html http://secunia.com/advisories/56186 http://secunia.com/advisories/56446 http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://www.debian.org/security/2014/dsa-2846 http://www.ubuntu.com/usn/USN-2093-1 https://bugzilla • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The lxcDomainGetMemoryParameters method in lxc/lxc_driver.c in libvirt 1.0.5 through 1.2.0 does not properly check the status of LXC guests when reading memory tunables, which allows local users to cause a denial of service (NULL pointer dereference and libvirtd crash) via a guest in the shutdown status, as demonstrated by the "virsh memtune" command. El método lxcDomainGetMemoryParameters en lxc/lxc_driver.c en libvirt 1.0.5 a 1.2.0 no comprueba correctamente el estado de invitados LXC cuando lee configuraciones de memoria, lo cual permite a usuarios locales causar denegación de servicio (referencia a puntero a NULL y caída de libvirtd) a través de un invitado en el estado de apagado, como se demuestra con el comando "virsh memtune". • http://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=f8c1cb90213508c4f32549023b0572ed774e48aa http://lists.opensuse.org/opensuse-updates/2014-01/msg00004.html http://osvdb.org/101485 http://secunia.com/advisories/56245 http://secunia.com/advisories/60895 http://security.gentoo.org/glsa/glsa-201412-04.xml http://www.ubuntu.com/usn/USN-2093-1 https://www.redhat.com/archives/libvir-list/2013-December/msg01170.html • CWE-264: Permissions, Privileges, and Access Controls •
