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/golang-github-msteinert-pam-0.0~git20170830.0.f4cd9f5/transaction.c FINAL RESULTS: data/golang-github-msteinert-pam-0.0~git20170830.0.f4cd9f5/transaction.c:21:6: [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.
