The alloc_domain_struct function in arch/arm/domain.c in Xen 4.4.x, when running on an ARM platform, does not properly initialize the structure containing the grant table pages for a domain, which allows local guest administrators to obtain sensitive information via the GNTTABOP_setup_table subhypercall. La función alloc_domain_struct en arch/arm/domain.c en Xen 4.4.x, cuando funciona en una plataforma ARM, no inicializa debidamente la estructura que contiene las páginas de tablas de permisos para un dominio, lo que permite a administradores locales invitados obtener información sensible a través de la subhiperllamada GNTTABOP_setup_table. • http://secunia.com/advisories/59523 http://www.securityfocus.com/bid/68184 http://www.securitytracker.com/id/1030471 http://xenbits.xen.org/xsa/advisory-101.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2014-4021
Xen 3.2.x through 4.4.x does not properly clean memory pages recovered from guests, which allows local guest OS users to obtain sensitive information via unspecified vectors. Xen 3.2.x hasta 4.4.x no limpia debidamente las páginas de memoria recuperadas de invitados, lo que permite a usuarios locales del sistema operativo invitado obtener información sensible a través de vectores no especificados. It was found that the Xen hypervisor implementation did not properly clean memory pages previously allocated by the hypervisor. A privileged guest user could potentially use this flaw to read data relating to other guests or the hypervisor itself. • http://linux.oracle.com/errata/ELSA-2014-0926-1.html http://linux.oracle.com/errata/ELSA-2014-0926.html http://lists.fedoraproject.org/pipermail/package-announce/2014-July/135068.html http://lists.fedoraproject.org/pipermail/package-announce/2014-July/135071.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00003.html http://secunia.com/advisories/59208 http://secunia.com/advisories/60027 http:// • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-244: Improper Clearing of Heap Memory Before Release ('Heap Inspection') •
