Unbounded write

[b4yuan]

In src/jose.c:

  if ((i = ArgPos((char *) "-train", argc, argv)) > 0) strcpy(train_file, argv[i + 1]);
  if ((i = ArgPos((char *) "-save-vocab", argc, argv)) > 0) strcpy(save_vocab_file, argv[i + 1]);
  if ((i = ArgPos((char *) "-read-vocab", argc, argv)) > 0) strcpy(read_vocab_file, argv[i + 1]);
  if ((i = ArgPos((char *) "-load-emb", argc, argv)) > 0) strcpy(load_emb_file, argv[i + 1]);
  if ((i = ArgPos((char *) "-debug", argc, argv)) > 0) debug_mode = atoi(argv[i + 1]);
  if ((i = ArgPos((char *) "-alpha", argc, argv)) > 0) alpha = atof(argv[i + 1]);
  if ((i = ArgPos((char *) "-word-output", argc, argv)) > 0) strcpy(word_emb, argv[i + 1]);
  if ((i = ArgPos((char *) "-context-output", argc, argv)) > 0) strcpy(context_emb, argv[i + 1]);
  if ((i = ArgPos((char *) "-doc-output", argc, argv)) > 0) strcpy(doc_output, argv[i + 1]);

Usage of strcpy here with an input from argv might overflow in the destination... perhaps switch to strncpy
