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/python-bitarray-0.8.1/bitarray/_bitarray.c FINAL RESULTS: data/python-bitarray-0.8.1/bitarray/_bitarray.c:119:13: [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 buff[256]; data/python-bitarray-0.8.1/bitarray/_bitarray.c:120:13: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(buff, "cannot create bitarray of size %lld, " data/python-bitarray-0.8.1/bitarray/_bitarray.c:399:12: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
