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/mpfrc++-3.6.8+ds/example/example.cpp Examining data/mpfrc++-3.6.8+ds/mpreal.h FINAL RESULTS: data/mpfrc++-3.6.8+ds/mpreal.h:451:25: [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. friend const mpreal random(unsigned int seed); data/mpfrc++-3.6.8+ds/mpreal.h:2727:21: [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. inline const mpreal random(unsigned int seed = 0) data/mpfrc++-3.6.8+ds/mpreal.h:2744:27: [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. if(seed != 0) std::srand(seed); data/mpfrc++-3.6.8+ds/mpreal.h:620:14: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120).
