Since this is the kind of mess no one wants to clean up, you can play it safe by sticking with strong zip-top bags and flexible plastic containers when freezing food. Of course, this doesn't mean you have to stop reusing glass jars entirely; they can come in handy for short-term storage in the fridge.
If, however, you still would prefer to freeze food in glass instead of plastic, there is definitely a safer option than using jars for the task. The New York Times recommends the Pyrex 18-piece simply food storage set. The tempered glass is easier to clean than most plastic, won't absorb food smells, and claims to be freezer and microwave safe. However, Pyrex does warn against taking the storage dishes from the freezer and placing them directly into a hot oven, as the drastic temperature change can cause them to shatter. Basically, you want to avoid ever heating or cooling glass too quickly (via Epicurious). Take it slowly, and you're sure to avoid a big mess and an even bigger headache.
