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/proftpd-mod-msg-0.5/mod_msg.c FINAL RESULTS: data/proftpd-mod-msg-0.5/mod_msg.c:75:3: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
