Hallo,
Regarding the concern about some dangerous functions in the Lua
library, it's not necessary to have a custom Lua distribution to
disable them. All one has to do is to set the functions to nil right
after the library initialisation in lua.cc:
luaopen_base(st);
luaopen_io(st);
luaopen_string(st);
luaopen_math(st);
luaopen_table(st);
luaopen_debug(st);
// disabling os.execute
lua_pushstring(st, "os");
lua_gettable(st, LUA_GLOBALSINDEX);
lua_pushstring(st, "execute");
lua_pushnil(st);
lua_settable(st, -3);
lua_pop(st, 1);
And after this the os.execute() function will be garbage collected.
