Examining data/since-1.1/since.c

FINAL RESULTS:

data/since-1.1/since.c:331:5:  [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(tmp, path);
data/since-1.1/since.c:333:5:  [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(tmp + plen + 1, append);
data/since-1.1/since.c:823:14:  [4] (format) snprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
    result = snprintf(line, MAX_FMT, sn->s_fmt, df->d_dev, df->d_ino, 0);
data/since-1.1/since.c:1504:16:  [4] (format) snprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
      result = snprintf(target, sn->s_fmt_output + 1, sn->s_fmt, df->d_dev, df->d_ino, df->d_pos);
data/since-1.1/since.c:168:6:  [3] (buffer) realpath:
  This function does not protect against buffer overflows, and some
  implementations can overflow internally (CWE-120/CWE-785!). Ensure that the
  destination buffer is at least of size MAXPATHLEN, andto protect against
  implementation problems, the input argument should also be checked to
  ensure it is no larger than MAXPATHLEN.
  if(realpath(sn->s_name, canon) == NULL){
data/since-1.1/since.c:388:9:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
  ptr = getenv("SINCE");
data/since-1.1/since.c:393:9:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
  ptr = getenv("HOME");
data/since-1.1/since.c:85:3:  [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 s_fmt[MAX_FMT];
data/since-1.1/since.c:165:3:  [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 canon[PATH_MAX], tmp[PATH_MAX], *tptr;
data/since-1.1/since.c:189:9:  [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).
  nfd = open(tmp, flags, mode);
data/since-1.1/since.c:351:14:  [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).
  sn->s_fd = open(sn->s_name, flags, mode);
data/since-1.1/since.c:558:3:  [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 line[MAX_FMT], *ptr;
data/since-1.1/since.c:602:7:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
      memcpy(line + k, ptr, end[x]);
data/since-1.1/since.c:759:8:  [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).
  fd = open(name, O_RDONLY);
data/since-1.1/since.c:812:3:  [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.

  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 buffer[IO_BUFFER];
data/since-1.1/since.c:1622:32:  [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).
          sn->s_delay.tv_sec = atoi(argv[i] + j);
data/since-1.1/since.c:321:12:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
