You would not flash-freeze nor explode in space. Heat transfer in space is pitiful (you would only radiate, not conduct and that would take a while) and the compressiblility of the body means you do not explode (NASA are very specific on this and can offer real-life examples of people exposed to zero pressure environments, and they are fine!)
However, it would NOT be very pleasant and you would be in serious trouble very quickly, especially if you tried to breathe or had any air in your lungs! (the people I mentioned above are only fine because they weren't exposed for very long!)
Luckily, Star Wars rarely has much to do woth real science and so this can be ignored.
