The signal wire (with the pulse width signal) can be connected to the servo.
The power for the servo can not be supplied by the Arduino. You need a seperate power supply for the servo motor.How high is the risk of blowing up the Arduino?
Small risk of blowing up, as either the automatic over-current/over-temp protection of the on-board 5 volt regulator or the on-board 500 ma thermofuse if using USB power will prevent lasting damage, however you most likely end up with a very unreliable system with lots of resets, freeze ups, or other weird symptoms.
