I will depart slightly from what my esteemed colleagues have said but only slightly. From my experience the big thing you have in your corner is that the cookies are thin. If they were 3" to 4" and better in thickness you'd have some loss.
Don't coat them with paint.Especially latex. Latex paint has been engineered to be able to breathe so as not to trap moisture between the painted surface and the paint itslef; the exact thing you want to do when you seal end grain. Use Anchor Seal or some other suitable log sealer.
You should have sealed them immediately though. Thin cookies begin their destructive moisture-releasing immediately and even though the damage may not be apparent yet, there are micro-fissures which must be arrested immediately.
Red oak should not be as bad as White Oak either so if you get them coated before you see these tiny cracks, before they become checks, you might be okay. But you have got to get a thick coat of wax sealer on them now.
You can stand them upright leaning against one another in a sdahy place with no sun, and a humid place will actually help for the first few weeks, them move them to a place less humid but still out of the sun. Coat them thick and your loss should be minimal.
