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 •

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 •

The Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x allows local guests to cause a denial of service (kernel panic) via a malformed Message Signaled Interrupt (MSI) from a PCI device that is bus mastering capable that triggers a System Error Reporting (SERR) Non-Maskable Interrupt (NMI). El motor Intel VT-d Interrupt Remapping en Xen 3.3.x a la 4.3.x permite a invitados (guest) locales provocar una denegación de servicio (kernel panic) a través de un Message Signaled Interrupt (MSI) mal formado desde un dispositivo PCI que es capaz de provocar un System Error Reporting (SERR) Non-Maskable Interrupt (NMI). • http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2015-02/msg00010.html http://osvdb.org/96438 http://secunia.com/advisories/54341 http://www.openwall.com/lists/oss-security/2013/08/20/8 http://www.securityfocus.com/bid/61854 http://www.securitytracker.com/id/1028931 https://security.gentoo.org/glsa/201504-04 • 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 •

Xen 4.0.x, 4.1.x, and 4.2.x, when running on AMD64 processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one domain to determine portions of the state of floating point instructions of other domains, which can be leveraged to obtain sensitive information such as cryptographic keys, a similar vulnerability to CVE-2006-1056. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processors in a security-relevant fashion that was not addressed by the kernels. Xen v4.0.x, v4.1.x, y v4.2.x, cuando se ejecuta en procesadores AMD64, sólo guarda/restaura los registros FOP, FIP, y FDP x87 en FXSAVE/FXRSTOR cuando una excepción se encuentra pendiente, lo que permite un dominio para determinar las porciones del estado de las instrucciones de punto flotante de otros dominios, por lo que pueden ser aprovechados para obtener información confidencial, como claves criptográficas, una vulnerabilidad similar a CVE-2006-1056. NOTA: este es el comportamiento documentado de procesadores AMD64, pero no es consistente con procesadores Intel de modo relevante para la seguridad que no ha sido resuelto por los kernel. • 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/2013/06/03/1 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
