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 •
