The LM267X device should have no problem with this. The main area of concern would be the external passive components. If the output capacitor does not have a high enough voltage rating then it could be destroyed. If the short is to the switch output and not to the output capacitor cathode, then the capacitor is still in danger and the inductor could overheat. In either case the output voltage will go up and the IC will simply stop switching. There should be no reason to be concerned about the LM267X.
