Lua through 5.4.0 mishandles the interaction between stack resizes and
garbage collection, leading to a heap-based buffer overflow, heap-based
buffer over-read, or use-after-free.

Notes

Author Note
mdeslaur couldn’t reproduce on lua earlier than 5.4. No indication that earlier versions are vulnerable. Marking not-affected.
