FINAL RESULTS:
data/princeprocessor-0.22/src/pp.c:272:5: [4] (format) printf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
printf (USAGE_MINI[i], progname);
data/princeprocessor-0.22/src/pp.c:295:5: [4] (format) printf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
printf (USAGE_BIG[i], progname);
data/princeprocessor-0.22/src/pp.c:749:15: [3] (buffer) getopt_long:
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 ((c = getopt_long (argc, argv, "Vhs:l:o:c", long_options, &option_index)) != -1)
data/princeprocessor-0.22/src/pp.c:122:3: [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[BUFSIZ];
data/princeprocessor-0.22/src/pp.c:409:3: [2] (buffer) memcpy:

data/princeprocessor-0.22/src/pp.c:667:14: [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).
FILE *fp = fopen (SAVE_FILE, "w");
data/princeprocessor-0.22/src/pp.c:756:59: [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).
case IDX_PW_MIN: pw_min = atoi (optarg); break;

data/princeprocessor-0.22/src/pp.c:758:59: [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).

case IDX_WL_MAX: wl_max = atoi (optarg); break;
data/princeprocessor-0.22/src/pp.c:922:15: [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).

data/princeprocessor-0.22/src/pp.c:963:5: [2] (buffer) char:

maximum possible length.
char buf[BUFSIZ];

char pw_buf[BUFSIZ];
data/princeprocessor-0.22/src/mpz_int128.h:89:4: [1] (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). Risk is low because the source is a constant character.
strcpy(ptr, "0"); \
data/princeprocessor-0.22/src/pp.c:360:13: [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).
int len = strlen (buf);
