FINAL RESULTS:

data/python-os-ken-1.2.0/os_ken/tests/packet_data_generator2/gen.c:526:5:  [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.
    sprintf(ps.desc.name, "eth0");
data/python-os-ken-1.2.0/os_ken/tests/packet_data_generator2/gen.c:652:10:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
    fp = fopen(name, "wb");
data/python-os-ken-1.2.0/os_ken/tests/packet_data_generator2/gen.c:942:9:  [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 name[255];
