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/m17n-docs-1.6.2/utils/imdoc.c FINAL RESULTS: data/m17n-docs-1.6.2/utils/imdoc.c:64:4: [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 (cur_comment->line, buf + 4); data/m17n-docs-1.6.2/utils/imdoc.c:128:8: [4] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. sprintf (cmd, "convert -resize 50%% %s images/icon-%s", data/m17n-docs-1.6.2/utils/imdoc.c:130:17: [4] (shell) system: 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. result = system (cmd); data/m17n-docs-1.6.2/utils/imdoc.c:9:3: [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 line[256]; data/m17n-docs-1.6.2/utils/imdoc.c:30:3: [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[256]; data/m17n-docs-1.6.2/utils/imdoc.c:44:8: [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). fp = fopen (argv[1], "r"); data/m17n-docs-1.6.2/utils/imdoc.c:124:8: [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 cmd[1024]; data/m17n-docs-1.6.2/utils/imdoc.c:70:30: [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). mt = mtext_from_data (buf, strlen (buf), MTEXT_FORMAT_US_ASCII); ANALYSIS SUMMARY: Hits = 8 Lines analyzed = 222 in approximately 0.39 seconds (568 lines/second) Physical Source Lines of Code (SLOC) = 206 Hits@level = [0] 30 [1] 1 [2] 4 [3] 0 [4] 3 [5] 0 Hits@level+ = [0+] 38 [1+] 8 [2+] 7 [3+] 3 [4+] 3 [5+] 0 Hits/KSLOC@level+ = [0+] 184.466 [1+] 38.835 [2+] 33.9806 [3+] 14.5631 [4+] 14.5631 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
