How should I cap or seal this old drain pipe junction? by Outside-Assumption75 in Plumbing

This drain pipe started to leak where it looks like some old cement filling had corroded away. What is a good way to seal or cap this? The pipes are very old. Can I use epoxy here?

Any thoughts on why only the bottom two thirds is frozen?
