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/wmitime-0.5/wmitime.c FINAL RESULTS: data/wmitime-0.5/wmitime.c:125:21: [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(locale, argv[i+1]); data/wmitime-0.5/wmitime.c:347:5: [4] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. sprintf(OrigBlitStr, "%s", nl_langinfo(ABDAY_1 + clk->tm_wday)); data/wmitime-0.5/wmitime.c:357:5: [4] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. sprintf(OrigBlitStr, "%s", nl_langinfo(ABMON_1 + clk->tm_mon)); data/wmitime-0.5/wmitime.c:37:1: [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 wmitime_mask_bits[64*64]; data/wmitime-0.5/wmitime.c:55:1: [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 locale[256]; data/wmitime-0.5/wmitime.c:273:5: [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 blitstr[32]; data/wmitime-0.5/wmitime.c:286:9: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(blitstr, "%2i:%02i:%02i", i, clk->tm_min, clk->tm_sec); data/wmitime-0.5/wmitime.c:290:9: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(blitstr, "%02i:%02i:%02i", i, clk->tm_min, clk->tm_sec); data/wmitime-0.5/wmitime.c:335:5: [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 OrigBlitStr[20], BlitStr[20]; data/wmitime-0.5/wmitime.c:364:5: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(BlitStr, "%02i", clk->tm_mday); data/wmitime-0.5/wmitime.c:566:5: [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[1024]; data/wmitime-0.5/wmitime.c:569:5: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(buf, "%03i", num); data/wmitime-0.5/wmitime.c:91:6: [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). if (strlen(ProgName) >= 5) data/wmitime-0.5/wmitime.c:92:16: [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). ProgName += (strlen(ProgName) - 5); data/wmitime-0.5/wmitime.c:240:3: [1] (obsolete) usleep: This C routine is considered obsolete (as opposed to the shell command by the same name). The interaction of this function with SIGALRM and other timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead. usleep(100000); data/wmitime-0.5/wmitime.c:295:11: [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). len = strlen(blitstr); ANALYSIS SUMMARY: Hits = 16 Lines analyzed = 599 in approximately 0.02 seconds (27446 lines/second) Physical Source Lines of Code (SLOC) = 427 Hits@level = [0] 12 [1] 4 [2] 9 [3] 0 [4] 3 [5] 0 Hits@level+ = [0+] 28 [1+] 16 [2+] 12 [3+] 3 [4+] 3 [5+] 0 Hits/KSLOC@level+ = [0+] 65.5738 [1+] 37.4707 [2+] 28.103 [3+] 7.02576 [4+] 7.02576 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
