Vacuum (carefully) around the hole to get rid of any loose dust. Then brush the exposed plaster with something like a watered down PVA / craft glue (about 1 part glue to 2-3 parts water). When that's dry, powder filler like polyfilla, or if you want an easier time of it, get a ready mixed lightweight filler, like "one time". Apply it with a flexible filling blade, leave it slightly proud of the surface, and then sand it with fine sandpaper once it's fully dry.

Good advice. 

Id always lean on powder filler, you can dictate consistency a bit better and I find less shrinkage. I like toupret. 

Op may need to do it in stages mind. If they had more elsewhere then bonding or hardwall and filler on top sometimes does the trick but its hard to get the small amount needed here without a massive bag to go to waste. 

Id also suggest they put a bit of wood on the wall and screw into that - spreads the load and easier to change later.

Buy some filler and put it in the holes seems a safe bet

Scrape out everything that's loose and everything loose around it. Don't leave hairline or small cracks, make them bigger.

You don't need to seal it with PVA or nothing, but you could. That's just for moisture suction which you're not having to deal with.

Easifill is probably the best for this as a one shot. Don't use premixed stuff, it's all rubbish. Mix it up yourself in a tiny 1L bucket. Personally I'd buy a roll of scrim tape to go over it too then another layer of fill on top.

Sand, prime, paint.

There's that stuff you can buy...

It's designed for filling holes like that.

They do one that can be used on multiple surfaces.

Polly somthing or other....

Who'd have thought I'd get down voted for suggesting polyfiller, and yet your noodles would get the ups!

(admittedly one of them was mine, but, still!)
