FINAL RESULTS:

data/unmo3-0.6/mo3_parse.c:220:13:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
            sprintf(note,"%s%d", notes[notev], oct+1);
data/unmo3-0.6/mo3_parse.c:17:1:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
