If you have straight-in access to the fitting, you can cut off the pipe and
bore out the inside of the hub. Plumbing supply shops sell a tool to do
this - IIRC it's about $25 but looks like it should only be $5 - just a
stamped steel blade on a shaft with a centering piece to keep it in the
center of the pipe. They come in various sizes to match the nominal pipe
size. Once the pipe is out you just glue in new pieces.
You could also install a mission coupling - a rubber sleeve with stainless
hose clamps. These are commonly used in drainage applications, and the
smaller sizes come either plain or with a corrugated stainless steel sleeve
to add rigidity (required by code for some drainage applications, probably
not necessary for what you're doing). One of those would, however,. require
you to have an open end to slip the fitting onto the pipe - which could
later be patched with a PVC slip-coupling and glued. Or you could slit the
rubber mission coupling and use it with silicone and clamps, placing the
slit 180 degrees away from the leak.
If you're just going to "goop" it over, you might consider adding some
string wound around the joint and over the hub to strengthen the patch
against vibration cracking and give the whole thing some integrity.
