Examining data/nototools-0.2.13/nototools/glyph_image/glyph_image.c

FINAL RESULTS:

data/nototools-0.2.13/nototools/glyph_image/glyph_image.c:31:3:  [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 buf[32];
data/nototools-0.2.13/nototools/glyph_image/glyph_image.c:106:7:  [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(buf, "%d,%d", adv_int, adv_frac);
data/nototools-0.2.13/nototools/glyph_image/glyph_image.c:108:7:  [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(buf, "%d", adv_int);
data/nototools-0.2.13/nototools/glyph_image/glyph_image.c:149:20:  [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).
    pixel_height = atoi(argv[2]);
data/nototools-0.2.13/nototools/glyph_image/glyph_image.c:156:19:  [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).
    first_glyph = atoi(argv[3]);
data/nototools-0.2.13/nototools/glyph_image/glyph_image.c:159:18:  [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).
    last_glyph = atoi(argv[4]);
