Buffer overflow in the Python bindings for the xc_vcpu_setaffinity call in Xen 4.0.x, 4.1.x, and 4.2.x allows local administrators with permissions to configure VCPU affinity to cause a denial of service (memory corruption and xend toolstack crash) and possibly gain privileges via a crafted cpumap. Desbordamiento de búfer en los enlaces de Python para la llamada xc_vcpu_setaffinity en Xen v4.0.x, v4.1.x, y v4.2.x permite a los administradores locales con permisos, configurar la afinidad de VCPU para causar una denegación de servicio (corrupción de memoria y caída de "xend toolstack") y, posiblemente, obtener privilegios a través de un "cpumap" manipulado. • http://lists.fedoraproject.org/pipermail/package-announce/2013-May/106718.html http://lists.fedoraproject.org/pipermail/package-announce/2013-May/106721.html http://lists.fedoraproject.org/pipermail/package-announce/2013-May/106778.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://www.debian.org/security/2014/dsa-3041 http://www.openwall.com/lists/oss-security/2013/05/17/2 http://www.securityfocus.com/bid/59982 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Xen 4.0.x, 4.1.x, and 4.2.x does not properly restrict the contents of a XRSTOR, which allows local PV guest users to cause a denial of service (unhandled exception and hypervisor crash) via unspecified vectors. Xen 4.0.x, 4.1.x, y 4.2.x no restringe adecuadamente los contenidos de un XRSTOR, lo que permite a usuarios locales "PV Guest" provocar una denegación de servicio (excepción sin controlar y caída del hypervisor) a través de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://www.debian.org/security/2014/dsa-3006 http://www.openwall.com/lists/oss-security/2013/06/03/2 • CWE-264: Permissions, Privileges, and Access Controls •

The libxenlight (libxl) toolstack library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions for xenstore keys for paravirtualised and emulated serial console devices, which allows local guest administrators to modify the xenstore value via unspecified vectors. La biblioteca libxenlight (libxl) toolstack ein Xen 4.0.x, 4.1.x, y 4.2.x utiliza permisos débiles para claves xenstore para dispositivos paravirtualizados y emulados de consola serie, lo que permite a administradores invitados (guest) la modificación del valor xenstore a través de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://www.debian.org/security/2014/dsa-3006 http://www.openwall.com/lists/oss-security/2013/06/25/1 http://www.openwall.com/lists/oss-security/2013/06/26/4 • CWE-264: Permissions, Privileges, and Access Controls •

Xen 4.1.x and 4.2.x, when the XSA-45 patch is in place, does not properly maintain references on pages stored for deferred cleanup, which allows local PV guest kernels to cause a denial of service (premature page free and hypervisor crash) or possibly gain privileges via unspecified vectors. Xen versiones 4.1.x y 4.2.x, cuando el parche XSA-45 está en su lugar, no mantiene apropiadamente las referencias sobre las páginas almacenadas para una limpieza diferida, lo que permite a los kernels invitados PV locales causar una denegación de servicio (liberación de página prematura y bloqueo del hipervisor) o posiblemente conseguir privilegios por medio de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://support.citrix.com/article/CTX138134 http://www.debian.org/security/2014/dsa-3006 http://www.openwall.com/lists/oss-security/2013/06/26/5 • CWE-399: Resource Management Errors •

The vmx_set_uc_mode function in Xen 3.3 through 4.3, when disabling caches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service (CPU consumption and possibly hypervisor or guest kernel panic) via a crafted GFN range. La función vmx_set_uc_mode en Xen 3.3 hasta la versión 4.3, al deshabilitar cachés, permite a invitados HVM locales con a las regiones I/O asignadas a la memoria provocar una denegación de servicio (consumo de CPU y posiblemente pánico de hypervisor o de kérnel invitado) a través de un rango GFN manipulado. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00021.html http://www.openwall.com/lists/oss-security/2013/07/24/6 https://security.gentoo.org/glsa/201504-04 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
