The guest_physmap_mark_populate_on_demand function in Xen 4.2 and earlier does not properly unlock the subject GFNs when checking if they are in use, which allows local guest HVM administrators to cause a denial of service (hang) via unspecified vectors. La función guest_physmap_mark_populate_on_demand en Xen v4.2 y anteriores no desbloquea correctamente los GFNs al comprobar si están en uso, lo que permite causar una denegación de servicio (caída del HVM)a los administradores de HVM invitados locales a través de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2013-01/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-updates/2013-04/msg00051.html http://lists.opensuse.org/opensuse-updates/2013-04/msg00052.html http •

Xen 4.x, when downgrading the grant table version, does not properly remove the status page from the tracking list when freeing the page, which allows local guest OS administrators to cause a denial of service (hypervisor crash) via unspecified vectors. Xen v4.x, cuando se baja la versión de la tabla de permisos, no elimina correctamente la página de estado de la lista de seguimiento cuando libera la página, lo que permite causar una denegación de servicio (caída del hipervisor) a los administradores de sistemas operativos huespedes del HVM local a través de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2013-01/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-updates/2013-04/msg00051.html http://lists.opensuse.org/opensuse-updates/2013-04/msg00052.html http •

The (1) XENMEM_decrease_reservation, (2) XENMEM_populate_physmap, and (3) XENMEM_exchange hypercalls in Xen 4.2 and earlier allow local guest administrators to cause a denial of service (long loop and hang) via a crafted extent_order value. Las hiperllamadas (1) XENMEM_decrease_reservation, (2) XENMEM_populate_physmap, y (3) XENMEM_exchange en Xen v4.2 y anteriores permiten a los administradores invitados locales causar una denegación de servicio (bucle largo y cuelgue) a través de un valor modificado de "extent_order". • http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2013-01/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2014-04 •

https://notcve.org/view.php?id=CVE-2012-5513
The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range. El manejador XENMEM_exchange en Xen v4.2 y anteriores no comprueba correctamente la dirección de memoria, lo que permite causar una denegación de servicio (caída del S.O.) a administrador de sistemas operativos invitados PV o posiblemente obtener privilegios a través de vectores no especificados que sobrescriben memoria en rangos del hipervisor reservados. • http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2013-01/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2014-04 • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
