Examining data/onesixtyone-0.3.3~git20190328/onesixtyone.c

FINAL RESULTS:

data/onesixtyone-0.3.3~git20190328/onesixtyone.c:399:3:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
  strcpy((buf + 7), target_community);
data/onesixtyone-0.3.3~git20190328/onesixtyone.c:439:5:  [4] (format) vprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    vprintf(fmt, args2);
data/onesixtyone-0.3.3~git20190328/onesixtyone.c:444:5:  [4] (format) vfprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    vfprintf(o.log_fd, fmt, args);
data/onesixtyone-0.3.3~git20190328/onesixtyone.c:277:17:  [3] (buffer) getopt:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
  while ((arg = getopt(argc, argv, "c:di:o:p:s:w:q")) != EOF) {
data/onesixtyone-0.3.3~git20190328/onesixtyone.c:115:13:  [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).
  if ((fd = fopen(filename, "r")) == 0) {
data/onesixtyone-0.3.3~git20190328/onesixtyone.c:165:15:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
    netmask = atoi(slash + 1);
data/onesixtyone-0.3.3~git20190328/onesixtyone.c:211:3:  [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.

data/onesixtyone-0.3.3~git20190328/onesixtyone.c:301:25:  [2] (integer) atol:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).

  Make sure destination can always hold the source data.
