Descriptions
Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions.
Xen, cuando se ejecuta en un hipervisor de 64-bit, permite a usuarios locales del SO invitado x86 modificar memoria arbitraria y consecuentemente obtener información sensible, provocar una denegación de servicio (caída del host), o ejecutar código arbitrario en el host aprovechando la emulación rota de instrucciones de prueba de bits.
Multiple vulnerabilities have been found in Xen, the worst of which could lead to the execution of arbitrary code on the host system. Versions less than 4.7.1-r4 are affected.
