NOTE: The LuaJIT project owner states that the debug libary is unsafe by definition and that this is not a vulnerability. When LuaJIT was originally developed the expectation was that the entire debug library had no security guarantees and thus it made no sense to assign CVEs. However not all users of later LuaJIT derivatives share this perspective.
