FINAL RESULTS:
data/hiredis-1.0.0/examples/example-push.c:40:9: [4] (format) fprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
fprintf(stderr, "%s:%d:%s(): " fmt, __FILE__, __LINE__, __func__, __VA_ARGS__); \
data/hiredis-1.0.0/sds.c:522:9: [4] (format) vsnprintf:
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.
vsnprintf(buf, buflen, fmt, cpy);
data/hiredis-1.0.0/sds.h:237:27: [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.
__attribute__((format(printf, 2, 3)));
data/hiredis-1.0.0/test.c:62:47: [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 test(_s) { printf("#%02d ", ++tests); printf(_s); }
data/hiredis-1.0.0/test.c:1311:24: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.
test_unix_socket = access(cfg.unix_sock.path, F_OK) == 0;
data/hiredis-1.0.0/win32.h:23:9: [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.
#ifndef snprintf
data/hiredis-1.0.0/win32.h:24:9: [4] (format) snprintf:

a constant for the format specification.
#define snprintf c99_snprintf
