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/verse-0.22.8/verse.c FINAL RESULTS: data/verse-0.22.8/verse.c:19:1: [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 sstring[10]; /* String to look for */ data/verse-0.22.8/verse.c:27:2: [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(sstring,"R%02d%02d",local_time->tm_mon+1,local_time->tm_mday); data/verse-0.22.8/verse.c:31:4: [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). f=fopen(VERSE_LIB,"r"); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 60 in approximately 0.01 seconds (5727 lines/second) Physical Source Lines of Code (SLOC) = 44 Hits@level = [0] 2 [1] 0 [2] 3 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 5 [1+] 3 [2+] 3 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 113.636 [1+] 68.1818 [2+] 68.1818 [3+] 0 [4+] 0 [5+] 0 Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
