Open Question: Will a pack of wolves/coyotes attack you if you are alone in a forest at night time?

I live beside a forest and sometime at night, I hear a pack of coyotes yelping/howling. It realy freaks me out, but it raised the question. If someone is alone in a forest at night, will a pack of coyotes or wolves attack them? Thanks!
