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/assembly-stats-1.0.1+ds/assembly-stats.cpp Examining data/assembly-stats-1.0.1+ds/fasta.cpp Examining data/assembly-stats-1.0.1+ds/fasta.h Examining data/assembly-stats-1.0.1+ds/fasta_unittest.cpp Examining data/assembly-stats-1.0.1+ds/fastq.cpp Examining data/assembly-stats-1.0.1+ds/fastq.h Examining data/assembly-stats-1.0.1+ds/fastq_unittest.cpp Examining data/assembly-stats-1.0.1+ds/filetype.cpp Examining data/assembly-stats-1.0.1+ds/filetype.h Examining data/assembly-stats-1.0.1+ds/filetype_unittest.cpp Examining data/assembly-stats-1.0.1+ds/stats.cpp Examining data/assembly-stats-1.0.1+ds/stats.h Examining data/assembly-stats-1.0.1+ds/stats_unittest.cpp FINAL RESULTS: data/assembly-stats-1.0.1+ds/assembly-stats.cpp:100:29: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190). If source untrusted, check both minimum and maximum, even if the input had no minus sign (large numbers can roll over into negative number; consider saving to an unsigned value if that is intended). ops.minLength = atoi(argv[ops.infileStartIndex + 1]); data/assembly-stats-1.0.1+ds/filetype.cpp:20:9: [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). ifs.open(filename.c_str()); data/assembly-stats-1.0.1+ds/stats.cpp:35:14: [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?
