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");
