The do_tmem_control function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly check privileges, which allows local guest OS users to access control stack operations via unspecified vectors. NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others. La función do_tmem_control en el Transcendent Memory (TMEM) en Xen v4.0, v4.1, y v4.2 no comprueba correctamente los privilegios, lo que permite a los usuarios del SO de invitado acceder a las operaciones de la pila mediante vectores no especificados. NOTA: este problema se publicó originalmente como parte de CVE-2012-3497, que era demasiado general; CVE-2012-3497 se ha dividido en este ID y otros. • http://lists.xen.org/archives/html/xen-announce/2012-09/msg00006.html http://osvdb.org/85199 http://secunia.com/advisories/50472 http://secunia.com/advisories/55082 http://security.gentoo.org/glsa/glsa-201309-24.xml http://wiki.xen.org/wiki/Security_Announcements#XSA-15_multiple_TMEM_hypercall_vulnerabilities http://www.openwall.com/lists/oss-security/2012/09/05/8 http://www.securityfocus.com/bid/55410 http://www.securitytracker.com/id?1027482 https://exchange.xforce.ibmcloud& • CWE-264: Permissions, Privileges, and Access Controls •

The physdev_get_free_pirq hypercall in arch/x86/physdev.c in Xen 4.1.x and Citrix XenServer 6.0.2 and earlier uses the return value of the get_free_pirq function as an array index without checking that the return value indicates an error, which allows guest OS users to cause a denial of service (invalid memory write and host crash) and possibly gain privileges via unspecified vectors. La hypercall physdev_get_free_pirq en arch/x86/physdev.c en Xen v4.1.x y Citrix XenServer v6.0.2 y anteriores utiliza el valor devuelto por la función get_free_pirq como un índice de la matriz sin comprobar que el valor de retorno indica un error, permitiendo a los huéspedes del OS invitado causar una denegación de servicio (escritura de memoria no válidas y caída del host) y, posiblemente, obtener privilegios a través de vectores no especificados. • http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2012-09/msg00017.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.xen.org/archives/html/xen-announce/2012-09/msg00001.html http://secunia.com/advisories/51413 http://secunia.com&#x • CWE-20: Improper Input Validation •
