The IRQ setup in Xen 4.2.x and 4.3.x, when using device passthrough and configured to support a large number of CPUs, frees certain memory that may still be intended for use, which allows local guest administrators to cause a denial of service (memory corruption and hypervisor crash) and possibly execute arbitrary code via vectors related to an out-of-memory error that triggers a (1) use-after-free or (2) double free. La configuración de IRQ en Xen 4.2.x y 4.3.x, utilizando passthrough de dispositivos y configurado para soportar un gran número de CPUs, libera cierta memoria que todavía puedan destinarse a su utilización, lo que permite a los administradores de los huéspedes locales provocar una denegación de servicio (corrupción de memoria y caída de hipervisor) y posiblemente ejecutar código arbitrario a través de vectores relacionados con un error de falta de memoria que provoca un fallo de (1) uso después de liberación o (2) doble liberación de memoria. • http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127580.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127607.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00011.html http://osvdb.org/102406 http://secunia.com/advisories/56557 http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists/oss-security/2014/01/23/4 http://www.securityfocus.com/bid/65097 http://www.securitytracker.com/id/1029679&# • CWE-399: Resource Management Errors •

The do_physdev_op function in Xen 4.1.5, 4.1.6.1, 4.2.2 through 4.2.3, and 4.3.x does not properly restrict access to the (1) PHYSDEVOP_prepare_msix and (2) PHYSDEVOP_release_msix operations, which allows local PV guests to cause a denial of service (host or guest malfunction) or possibly gain privileges via unspecified vectors. La función do_physdev_op en Xen 4.1.5, 4.1.6.1, 4.2.2 hasta 4.2.3 y 4.3.x no restringe adecuadamente el acceso a las operaciones: (1) PHYSDEVOP_release_msix y (2) PHYSDEVOP_prepare_msix , lo que permite a los huéspedes PV locales provocar una denegación de servicio ( mal funcionamiento de host o invitado) o posiblemente obtener privilegios a través de vectores no especificados. • http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127580.html http://lists.fedoraproject.org/pipermail/package-announce/2014-February/127607.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00011.html http://osvdb.org/102536 http://secunia.com/advisories/56650 http://security.gentoo.org/glsa/glsa-201407-03.xml http://support.citrix.com/article/CTX200288 http://www.openwall.com/lis • CWE-264: Permissions, Privileges, and Access Controls •

The qdisk PV disk backend in qemu-xen in Xen 4.2.x and 4.3.x before 4.3.1, and qemu 1.1 and other versions, allows local HVM guests to cause a denial of service (domain grant reference consumption) via unspecified vectors. El backend PV qdisk en qemu-xen de Xen 4.2.x y 4.3.x anteriores a 4.3.1, y qemu 1.1 y otras versiones, permite a invitados locales HVM causar una denegación de servicio (consumo de referencia de concesión de dominio) a través de vectores no especificados. • http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists/oss-security/2013/10/10/14 http://www.ubuntu.com/usn/USN-2092-1 http://xenproject.org/downloads/xen-archives/supported-xen-43-series/xen-431.html • CWE-399: Resource Management Errors •

Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. Xen 3.0.3 a 4.1.x (posiblemente 4.1.6.1), 4.2.x (posiblemente 4.2.3), y 4.3.x (posiblemente 4.3.1) no previene correctamente acceso a hypercalls, lo cual permite a usuarios invitados locales obtener privilegios a través de la ejecución de una aplicación manipulada en el anillo 1 o el anillo 2. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2014-04/msg00000.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00059.html http://rhn.redhat.com/errata/RHSA-2014-0285.html http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists&# • CWE-264: Permissions, Privileges, and Access Controls •
