Descriptions

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

** EN DISPUTA ** En LuaJIT hasta la versión 2.0.5, como se usaba en Moonjit antes de 2.1.2 y otros productos, debug.getinfo tiene un problema de confusión de tipos que conduce a operaciones arbitrarias de escritura o lectura de memoria, porque ciertos casos involucran niveles de pila válidos y > las opciones se manejan mal. NOTA: El propietario del proyecto LuaJIT declara que la biblioteca de depuración no es segura por definición y que esto no es una vulnerabilidad. Cuando LuaJIT se desarrolló originalmente, la expectativa era que toda la biblioteca de depuración no tenía garantías de seguridad y, por lo tanto, no tenía sentido asignar CVE. Sin embargo, no todos los usuarios de derivados posteriores de LuaJIT comparten esta perspectiva.
