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 •

The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors. La llamada HVMOP_pagetable_dying en Xen v4.0, v4.1, y v4.2 no comprueba correctamente el estado "pagetable" cuando se ejecuta en "shadow pagetables", lo que permite a un sistema operativo HVM de invitado causar una denegación de servicio (caída del hipervisor) a través de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00017.html http://lists.opensuse.org/opensuse-security-announce/2012-11/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2012-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://lists.xen.org/archives/html/xen-announce/2012-11&#x • CWE-20: Improper Input Validation •
