CVE-2019-19391

DISPUTED In LuaJIT through 2.0.5, as used in Moonjit before 2.1.2 and
other products, debug.getinfo has a type confusion issue that leads to
arbitrary memory write or read operations, because certain cases involving
valid stack levels and > options are mishandled. 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.
