As for a repair to holes, personally think not needed as you will be drilling through these holes from one side to anotherBest to change the latch as well for a ‘bolt through tubular latch’ then no problem with using 4 handle bolts Again, good chance of 1 or more bolts fouling on the latch so swap out current latch for a 'bolt through tubular latch' Could do away with the latch and swap for one of these as its a stairs cupboard; (as an example only) M3 no snap off screw – can be cut with electrician pliers Both the sleeve and the screw has a slotted head.
