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-yuin-goldmark-1.2.1/_benchmark/cmark/cmark_benchmark.c FINAL RESULTS: data/golang-github-yuin-goldmark-1.2.1/_benchmark/cmark/cmark_benchmark.c:44:20: [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). n = argc > 1 ? atoi(argv[1]) : 50; data/golang-github-yuin-goldmark-1.2.1/_benchmark/cmark/cmark_benchmark.c:47:10: [2] (misc) fopen: 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). fp = fopen(markdown_file,"r"); ANALYSIS SUMMARY: Hits = 2 Lines analyzed = 91 in approximately 0.04 seconds (2341 lines/second) Physical Source Lines of Code (SLOC) = 76 Hits@level = [0] 11 [1] 0 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 13 [1+] 2 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 171.053 [1+] 26.3158 [2+] 26.3158 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 2 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
