I'm having a hard time seeing the problem with this buffer overflow problem can someone please elaborate if its secure or not, and if there are any other issues with the implementation in the problem?

Someone tries to fix the stack based buffer overflow problem as follows, is it secure now? why? Are there any other issues within the function's implementation below? Explain your reasoning.

int bof(char *str, int size)

{

  char *buffer = (char *) malloc(size);

  strcpy(buffer, str);

  return 1;

}
