FINAL RESULTS:
data/popt-1.18/src/popt.c:430:7: [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.
if (!access(t, X_OK))
data/popt-1.18/src/popt.c:532:10: [4] (shell) execvp:
This causes a new program to execute and is difficult to use safely
(CWE-78). try using a library call that implements the same functionality
if available.
rc = execvp(argv[0], (char *const *)argv);
data/popt-1.18/src/popt.c:1207:2: [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(stdout, POPT_("option type (%u) not implemented in popt\n"),
data/popt-1.18/src/popthelp.c:359:7: [4] (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).
strcpy(te, defs);
data/popt-1.18/src/popthelp.c:395:9: [4] (format) sprintf:
Potential format string problem (CWE-134). Make format string constant.
le += sprintf(le, (ops ? "0x%lx" : "%ld"), aLong);
data/popt-1.18/src/popthelp.c:461:3: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(format, "%%s\n%%%ds", (int) indentLength);
data/popt-1.18/src/poptint.c:159:7: [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.
rc = vsnprintf(b, nb, format, ap);
data/popt-1.18/src/poptparse.c:193:6: [4] (buffer) strcat:
Does not check for buffer overflows when concatenating to destination
