Descriptions
Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors.
Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x y versiones anteriores no inicializa registros de memoria de pila x86 FPU y XMM cuando XSAVE/XRSTOR no se utilizan para gestionar el estado del registro extendido de invitado, lo que permite a dominios de invitado local obtener información sensible de otros dominios a través de vectores no especificados.
