Not unless you get between it and its young. I can't really back this up, but I seem to remember a news article about a guy who had to spend some time up a tree due to an enraged moose. Also there have been incidents where hormonally disturbed animals entered populated areas and acted in a more or less threatening manner, but I can't recall anyone getting hurt by them.
I'd say the risk of a moose attack is probably well below the chance of getting hit by a meteorite, so can safely be ignored
