Prime the wall.
Apply a filler mesh to the wall so that it covers all cracks.
Cover the mesh with a thin layer of putty, wait until it dries and sand. It is done!

For the most reliable work, use Ceresit CT29 for putty. Not only that this putty is intended for external walls, it also does not need subsequent sanding.

Significant cracks

In this case, it will be necessary to work with a "native" wall, and therefore it will be necessary to completely remove the entire layer of plaster - this is not so much a complicated task as it is very dusty. After the plaster is removed, it will be necessary to screw a special metal mesh (you can buy it in any construction shop) to the wall and apply cement-sand plaster.
