As long as you are transiting within KLIA itself and not dealing with the completely separate LCC terminal building (which with CX and MH you shouldn't be), then KLIA transit is very easy and 70 minutes is a generous amount of time if everything is on time. Depending on arriving vs departure gates, you may have to take a quick (free) light rail link between two KLIA (main and satellite) terminal buildings. I vaguely recall another quick security check done as you enter the gate waiting area, it was pretty painless. IMO, KLIA is one of the easier airports in Asia to transit through, though it doesn't have the sort of extensive facilities and shopping as SIN does, it is adequate.
