      Such an event is called and emergency and the crew is trained for exactly this type of event.
      If it is a large leak, the crew has breathing masks, like a fireman on Earth. So they would always be able to move into their escape vehicle and return to Earth.
      If it is not such a bad leak, they can isolate the leaking module by closing doors (hatches). This is similar to a submarine which has water coming in!
      And finally, there is a leak repair kit. If the crew can find the hole, they have special material to block the hole and stop the leak.
      Fresh oxygen is always available from storage tanks.
