Isn't this why projects such as Homebrew thrive? For me personally, I just `brew install git`, and I keep it updated that way (`brew update && brew upgrade`)... Sure, Apple should ship a fix, but there are ways around it for now.
Sure, but your /usr/bin/git is still vulnerable. You're one config mistake (or maybe running a "malicious" script) away from executing.
I got the updated brew version downloaded already.
