Multiple integer overflows in the (1) FLASK_GETBOOL and (2) FLASK_SETBOOL suboperations in the flask hypercall in Xen 4.1.x, 3.3.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1891, CVE-2014-1892, and CVE-2014-1894. Múltiples desbordamientos de enteros en las suboperaciones (1) FLASK_GETBOOL y (2) FLASK_SETBOOL en la hiperllamada flask hypercall en Xen 4.1.x, 3.3.x, 3.2.x y anteriores, cuando XSM está habilitado, permiten a usuarios locales causar una denegación de servicio (fallo de procesador) a través de vectores no especificados, una vulnerabilidad diferente a CVE-2014-1891, CVE-2014-1892 y CVE-2014-1894. • 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://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists/oss-security/2014/02/07/12 http://www.openwall.com/lists/oss-security/2014/02/07/4 http://www.openwall.com/lists/oss-security/2014/02/10/8 http://xenbits.xen.org/xsa&#x • CWE-189: Numeric Errors •

Off-by-one error in the flask_security_avc_cachestats function in xsm/flask/flask_op.c in Xen 4.2.x and 4.3.x, when the maximum number of physical CPUs are in use, allows local users to cause a denial of service (host crash) or obtain sensitive information from hypervisor memory by leveraging a FLASK_AVC_CACHESTAT hypercall, which triggers a buffer over-read. Error de superación de límite (off-by-one) en la función flask_security_avc_cachestats en xsm/flask/flask_op.c en Xen 4.2.x y 4.3.x, cuando el número máximo de CPUs físicas están en uso, permite a usuarios locales causar una denegación de servicio (caída de host) u obtener información sensible de memoria del hipervisor mediante el aprovechamiento de una hiperllamada FLASK_AVC_CACHESTAT, lo que provoca una sobrelectura de buffer. • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00011.html http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists/oss-security/2014/02/07/12 http://www.openwall.com/lists/oss-security/2014/02/10/6 http://xenbits.xen.org/xsa/advisory-85.html • CWE-189: Numeric Errors •

The (1) do_send and (2) do_recv functions in io.c in libvchan in Xen 4.2.x, 4.3.x, and 4.4-RC series allows local guests to cause a denial of service or possibly gain privileges via crafted xenstore ring indexes, which triggers a "read or write past the end of the ring." Las funciones (1) do_send y (2) do_recv en io.c in libvchan en Xen 4.2.x, 4.3.x y series 4.4-RC permiten a invitados locales causar una denegación de servicio o posiblemente ganar privilegios a través de indices de anillo xenstore manipulados, lo que provoca un "leer o escribir pasado el final del anillo". • http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00011.html http://security.gentoo.org/glsa/glsa-201407-03.xml http://www.openwall.com/lists/oss-security/2014/02/07/12 http://www.openwall.com/lists/oss-security/2014/02/10/7 http://xenbits.xen.org/xsa/advisory-86.html http://xenbits.xen.org/xsa/xsa86.patch • CWE-20: Improper Input Validation •
