Using anonymous PL/SQL block you can achieve this by executing following code:
DECLARE
vDateC VARCHAR2(500) := '01/'||&month||'/'||&year;
vDate DATE := TO_DATE(vDateC,'DD/MM/YYYY');
vYear VARCHAR2(10);
vMonth VARCHAR2(3);
vYrCt VARCHAR2(100);
vMnCt VARCHAR2(100);
BEGIN
FOR i IN 1..12
LOOP
vYear := TO_CHAR(vDate,'YYYY');
vMonth := TO_CHAR(vDate,'MM');
vYrCt := vYrCt||vYear||chr(9);
vMnCt := vMnCt||vMonth||chr(9);
vDate := ADD_MONTHS(vDate,-1);
END LOOP;
DBMS_OUTPUT.put_line(vYrCt);
DBMS_OUTPUT.put_line(vMnCt);
END;
