Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/display-dhammapada-1.0/src/display-dhammapada.c FINAL RESULTS: data/display-dhammapada-1.0/src/display-dhammapada.c:211:8: [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(s2, s); data/display-dhammapada-1.0/src/display-dhammapada.c:259:6: [3] (random) srand: This function is not sufficiently random for security-related functions such as key and nonce creation (CWE-327). Use a more secure technique for acquiring random values. srand ((unsigned int) time (NULL)); data/display-dhammapada-1.0/src/display-dhammapada.c:51:8: [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. char begin[mark_length], end[mark_length]; data/display-dhammapada-1.0/src/display-dhammapada.c:136:6: [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 s[max_string_length]; data/display-dhammapada-1.0/src/display-dhammapada.c:161:6: [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 s[max_string_length]; data/display-dhammapada-1.0/src/display-dhammapada.c:193:6: [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 s[max_string_length]; data/display-dhammapada-1.0/src/display-dhammapada.c:196:6: [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 s2[max_string_length*2]; data/display-dhammapada-1.0/src/display-dhammapada.c:249:19: [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). if (number <= atoi (marks[index].end)) data/display-dhammapada-1.0/src/display-dhammapada.c:288:6: [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 dp_filename [200]; data/display-dhammapada-1.0/src/display-dhammapada.c:363:12: [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). dp = fopen (dp_filename, "rt"); data/display-dhammapada-1.0/src/display-dhammapada.c:213:17: [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). inleft = strlen(s2); ANALYSIS SUMMARY: Hits = 11 Lines analyzed = 385 in approximately 0.10 seconds (3946 lines/second) Physical Source Lines of Code (SLOC) = 353 Hits@level = [0] 11 [1] 1 [2] 8 [3] 1 [4] 1 [5] 0 Hits@level+ = [0+] 22 [1+] 11 [2+] 10 [3+] 2 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 62.3229 [1+] 31.1615 [2+] 28.3286 [3+] 5.66572 [4+] 2.83286 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
