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/dbskkd-cdb-3.00/dbskkd-cdb.c FINAL RESULTS: data/dbskkd-cdb-3.00/dbskkd-cdb.c:70:3: [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 combuf[BUFSIZE], data[DATASIZE]; data/dbskkd-cdb-3.00/dbskkd-cdb.c:77:16: [2] (misc) open: 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). if ((dicfd = open(JISYO_FILE, O_RDONLY, S_IRUSR)) < 0) { data/dbskkd-cdb-3.00/dbskkd-cdb.c:87:14: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). length = read(STDIN, &combuf[0], BUFSIZE - 1); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 177 in approximately 0.03 seconds (5586 lines/second) Physical Source Lines of Code (SLOC) = 108 Hits@level = [0] 0 [1] 1 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 3 [1+] 3 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 27.7778 [1+] 27.7778 [2+] 18.5185 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
