When lua_chown is used to call chown(2) internally, it first resolves the user and/or group by calling the getpwnam_r(3) and getgrnam_r(3) functions, respectively. However, although it checks for errors, it does not check when entries are not found (which is not an error), which means that the buffer will be set to NULL, and since lua_chown attempts to access the NULL structure, it will receive a SIGSEGV signal.
