Examining data/gbase-0.5/gbase.c

FINAL RESULTS:

data/gbase-0.5/gbase.c:51:1:  [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 buffer[33];

  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.

  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

    accumulator = strtoul(gtk_entry_get_text(GTK_ENTRY(entry)), (char **)NULL, bases[id]);
data/gbase-0.5/gbase.c:269:5:  [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(buffer, "%ld", accumulator);
data/gbase-0.5/gbase.c:273:7:  [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(buffer, "%lu", accumulator);
data/gbase-0.5/gbase.c:276:7:  [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(buffer, "%lX", accumulator);
data/gbase-0.5/gbase.c:279:7:  [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(buffer, "%lo", accumulator);
data/gbase-0.5/gbase.c:224:6:  [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).
  if(strlen(gtk_entry_get_text(GTK_ENTRY(entry))) == 0) {
data/gbase-0.5/gbase.c:384:30:  [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).
    if(bad_string(argv[i+1], strlen(argv[i+1]), type, 0)) {
