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/rsakeyfind-1.0/rsakeyfind.cpp FINAL RESULTS: data/rsakeyfind-1.0/rsakeyfind.cpp:52:5: [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. char tmp[4]; data/rsakeyfind-1.0/rsakeyfind.cpp:121:12: [2] (misc) open: 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). int fd = open(filename, O_RDONLY); data/rsakeyfind-1.0/rsakeyfind.cpp:141:5: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
