FINAL RESULTS:
data/pforth-21/csrc/pf_io.h:127:20: [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.
#define PRT(x) { printf x; sdFlushFile(PF_STDOUT); }
data/pforth-21/csrc/pf_main.c:28:21: [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.
#define ERR(msg) { printf msg; }
data/pforth-21/csrc/pf_cglue.c:94:2: [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 FName[40];
data/pforth-21/csrc/pf_clib.h:45:27: [2] (buffer) memcpy:
Does not check for buffer overflows when copying to destination (CWE-120).
Make sure destination can always hold the source data.
#define pfCopyMemory memcpy
data/pforth-21/csrc/pf_core.c:45:1: [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 gScratch[TIB_SIZE];
data/pforth-21/csrc/pf_core.c:283:2: [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[32];
data/pforth-21/csrc/pf_guts.h:377:2: [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 td_TIB[TIB_SIZE]; /* Buffer for terminal input. */
data/pforth-21/csrc/pf_guts.h:431:2: [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 inf_SaveTIB[TIB_SIZE];
data/pforth-21/csrc/pf_guts.h:455:8: [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.
extern char gScratch[TIB_SIZE];
data/pforth-21/csrc/pf_io.h:107:27: [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).
#define sdOpenFile fopen
data/pforth-21/csrc/pf_mem.c:40:9: [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.
static char MemoryPool[PF_MEM_POOL_SIZE];
data/pforth-21/csrc/pf_text.c:210:8: [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.
static char cnttPad[CNTT_PAD_SIZE];
data/pforth-21/csrc/pfcompil.c:631:2: [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 FName[40];
data/pforth-21/csrc/pf_clib.h:43:27: [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).
#define pfCStringLength strlen
data/pforth-21/csrc/pf_io.h:36:29: [1] (buffer) getchar:
Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).
#define sdTerminalIn getchar
data/pforth-21/csrc/pf_io.h:114:27: [1] (buffer) fgetc:
Check buffer boundaries if used in a loop including recursive loops
(CWE-120, CWE-20).
#define sdInputChar fgetc
