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-golang-freetype-0.0~git20170609.e2365df+dfsg/cmd/print-glyph-points/main.c FINAL RESULTS: data/golang-github-golang-freetype-0.0~git20170609.e2365df+dfsg/cmd/print-glyph-points/main.c:26:14: [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). font_size = atoi(argv[1]); ANALYSIS SUMMARY: Hits = 1 Lines analyzed = 87 in approximately 0.04 seconds (2020 lines/second) Physical Source Lines of Code (SLOC) = 78 Hits@level = [0] 13 [1] 0 [2] 1 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 14 [1+] 1 [2+] 1 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 179.487 [1+] 12.8205 [2+] 12.8205 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
