drywall repair around an outlet.
I have an old house with lathe and plaster walls. When I've gone in and replaced old boxes with new or just added in new boxes, I've actually used the spray foam in a can around loose boxes. You have to wait until the foam dries, about a day, then trim it away and back cut the foam just enough to mud over it. I tend to actually use some plaster of paris mixed with a small amount of drywall mud and it becomes hard as a rock, but smoothes out fairly easily.
I like this for several reasons....1) I've found when just using drywall mud, the patch is kind of weak and if someone pushes on the outlet very hard when plugging something in, it tends to crack out. 2) With my lathe and plaster walls, it also "glues" the lathe back to the plaster where I had to cut out the hole for the box. 3) It provides an air tight seal between the wall and the box, so no cold air seeps past!
This might be overkill for your fix, but it's an option...
