How Can I Replace Our Leaking Outdoor Faucet?

Question

Our outdoor faucet is leaking. Here's a picture:

Here's another picture that more clearly shows from where I think it's leaking:

I think I need to replace the faucet. The online resources I've found warn that the pipe must be held fast when unscrewing the faucet to avoid damage. However, the pipe isn't exposed outside the wall. Unfortunately, I can't get to the pipe from the other side, either. What is the best strategy to replace the leaky faucet? Will I need to remove a section of stucco?

As mentioned by Ecnerwal, the washer needs replacing that is around the stem. you can remove it with a wrench turning counter clockwise (CC)
Once it's free turn the handle CC to remove the washer assembly. You can also wrap Graphite string (or teflon tape) around the stem and under the nut.

Your indication of where it leaks from suggests that simply repacking the valve stem might fix your leak, without having to change the faucet.
If you do change the faucet, if the pipe in the basement is threaded, just unscrew it - either the pipe in the wall will unscrew, or the faucet will, and if the pipe in the wall is what unscrews, you can remove it from the faucet after it's out of the wall, attach it to the new faucet, and thread it back into the wall.
If your pipes in the basement, including this one, are soldered, you may need to unsolder it inside and pull the valve & pipe out to change the valve. One way or another that would require gaining access to the pipe.
