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/cqrlib-1.1.4/CPPQRTest.cpp Examining data/cqrlib-1.1.4/CQRlibTest.c Examining data/cqrlib-1.1.4/cqrlib.c Examining data/cqrlib-1.1.4/cqrlib.h FINAL RESULTS: data/cqrlib-1.1.4/CQRlibTest.c:56:17: [3] (random) random: 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. #define rand(x) random(x) data/cqrlib-1.1.4/CQRlibTest.c:57:9: [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. #define srand(x) srandom(x) data/cqrlib-1.1.4/CQRlibTest.c:57:18: [3] (random) srandom: 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. #define srand(x) srandom(x) ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 3727 in approximately 0.16 seconds (22986 lines/second) Physical Source Lines of Code (SLOC) = 2429 Hits@level = [0] 96 [1] 0 [2] 0 [3] 3 [4] 0 [5] 0 Hits@level+ = [0+] 99 [1+] 3 [2+] 3 [3+] 3 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 40.7575 [1+] 1.23508 [2+] 1.23508 [3+] 1.23508 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
