Examining data/dbskkd-cdb-3.00/dbskkd-cdb.c

FINAL RESULTS:

data/dbskkd-cdb-3.00/dbskkd-cdb.c:70:3:  [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 combuf[BUFSIZE], data[DATASIZE];
data/dbskkd-cdb-3.00/dbskkd-cdb.c:77:16:  [2] (misc) open:
  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).
  if ((dicfd = open(JISYO_FILE, O_RDONLY, S_IRUSR)) < 0) {
data/dbskkd-cdb-3.00/dbskkd-cdb.c:87:14:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    length = read(STDIN, &combuf[0], BUFSIZE - 1);
