FINAL RESULTS:

data/dune-grid-glue-2.7.0/dune/grid-glue/adapter/gridglue.cc:74:3:  [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.
  char patch0surf[256];
data/dune-grid-glue-2.7.0/dune/grid-glue/adapter/gridglue.cc:75:3:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
