Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving an asynchronous abort while at HYP. Xen hasta la versión 4.7.x permite a usuarios locales del SO ARM invitado provocar una denegación de servicio (caída del host) a través de vectores que implican un aborto asíncrono mientras en HYP. • http://www.openwall.com/lists/oss-security/2016/11/29/3 http://www.openwall.com/lists/oss-security/2016/12/05/7 http://www.securityfocus.com/bid/94581 http://www.securitytracker.com/id/1037358 http://xenbits.xen.org/xsa/advisory-201.html http://xenbits.xen.org/xsa/xsa201-4.patch https://security.gentoo.org/glsa/201612-56 • CWE-284: Improper Access Control •

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 through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations. Xen hasta la versión 4.8.x permite a administradores del kernel locales x86 PV invitados del SO provocar una denegación de servicio (cuelgue del anfitrión o caída) modificando el flujo de instrucciones asincrónicamente mientras se llevan a cabo ciertas operaciones del kernel. • http://www.debian.org/security/2017/dsa-3847 http://www.securityfocus.com/bid/95021 http://www.securitytracker.com/id/1037517 http://xenbits.xen.org/xsa/advisory-202.html https://security.gentoo.org/glsa/201612-56 https://support.citrix.com/article/CTX219378 • CWE-20: Improper Input Validation •

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') •

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 •
