CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix. Emulación CMPXCHG8B en Xen 3.3.x hasta la versión 4.7.x en sistemas x86 permite a usuarios locales HVM invitados del SO obtener información sensible de la memoria basada en pila del anfitrión a través de un prefijo de tamaño de operando "supuestamente ignorado". • http://www.debian.org/security/2017/dsa-3847 http://www.securityfocus.com/bid/94863 http://www.securitytracker.com/id/1037468 http://xenbits.xen.org/xsa/advisory-200.html https://security.gentoo.org/glsa/201612-56 https://support.citrix.com/article/CTX219378 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Xen 4.7.x and earlier does not properly honor CR0.TS and CR0.EM, which allows local x86 HVM guest OS users to read or modify FPU, MMX, or XMM register state information belonging to arbitrary tasks on the guest by modifying an instruction while the hypervisor is preparing to emulate it. Xen 4.7.x y versiones anteriores no respeta adecuadamente CR0.TS y CR0.EM, lo que permite a usuarios locales x86 HVM del SO invitado leer o modificar información del estado de registro FPU, MMX o XMM que pertenece a tareas arbitrarias en el invitado modificando una instrucción mientras que el hipervisor se prepara para emularlo. • http://www.securityfocus.com/bid/93344 http://www.securitytracker.com/id/1036942 http://xenbits.xen.org/xsa/advisory-190.html https://security.gentoo.org/glsa/201611-09 https://support.citrix.com/article/CTX217363 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Use-after-free vulnerability in the FIFO event channel code in Xen 4.4.x allows local guest OS administrators to cause a denial of service (host crash) and possibly execute arbitrary code or obtain sensitive information via an invalid guest frame number. Vulnerabilidad de uso después de liberación de memoria en el código de canal de evento FIFO en Xen 4.4.x permite a administradores locales del SO invitado provocar una denegación de servicio (caída de host) y posiblemente ejecutar código arbitrario u obtener información sensible a través de un número de marco invitado no válido. • http://support.citrix.com/article/CTX216071 http://www.c7zero.info/stuff/csw2017_ExploringYourSystemDeeper_updated.pdf http://www.debian.org/security/2016/dsa-3663 http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http://www.securityfocus.com/bid/92863 http://www.securitytracker.com/id/1036754 http://xenbits.xen.org/xsa/advisory-188.html http://xenbits.xen.org/xsa/xsa188.patch • CWE-416: Use After Free •

Xen 4.5.3, 4.6.3, and 4.7.x allow local HVM guest OS administrators to overwrite hypervisor memory and consequently gain host OS privileges by leveraging mishandling of instruction pointer truncation during emulation. Xen 4.5.3, 4.6.3 y 4.7.x permiten a administradores locales del SO invitado HVM sobreescribir memoria del hipervisor y consecuentemente obtener privilegios del SO anfitrión aprovechando el mal manejo del truncamiento del puntero de instrucción durante la emulación. • http://support.citrix.com/article/CTX216071 http://www.securityfocus.com/bid/92865 http://www.securitytracker.com/id/1036752 http://xenbits.xen.org/xsa/advisory-186.html http://xenbits.xen.org/xsa/xsa186-0001-x86-emulate-Correct-boundary-interactions-of-emulate.patch https://security.gentoo.org/glsa/201611-09 • CWE-264: Permissions, Privileges, and Access Controls •
