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/elkcode-6.3.2/utilities/xps/conv.c FINAL RESULTS: data/elkcode-6.3.2/utilities/xps/conv.c:66:3: [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 (time (NULL)); data/elkcode-6.3.2/utilities/xps/conv.c:70:7: [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 (argv[1], "r"); ANALYSIS SUMMARY: Hits = 2 Lines analyzed = 90 in approximately 0.33 seconds (274 lines/second) Physical Source Lines of Code (SLOC) = 65 Hits@level = [0] 7 [1] 0 [2] 1 [3] 1 [4] 0 [5] 0 Hits@level+ = [0+] 9 [1+] 2 [2+] 2 [3+] 1 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 138.462 [1+] 30.7692 [2+] 30.7692 [3+] 15.3846 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
