FINAL RESULTS:

data/node-zipfile-0.5.12+ds/src/node_zipfile.cpp:75:5:  [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.

  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
