Descriptions

The instruction emulation in Xen 3.0.3 allows local SMP guest users to cause a denial of service (host crash) by replacing the instruction that causes the VM to exit in one thread with a different instruction in a different thread.

La instrucción de emulación en Xen 3.0.3 permite a usuarios invitados SMP locales causar denegación de servicio (caída del anfitrión) reemplazando la instrucción que causa que la máquina virtual salga en un hilo con una instrucción deferente en un hilo distinto.
