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/xf86-input-xwiimote-0.5/src/xwiimote.c FINAL RESULTS: data/xf86-input-xwiimote-0.5/src/xwiimote.c:1253:9: [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). *out = atoi(t); data/xf86-input-xwiimote-0.5/src/xwiimote.c:1310:2: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy(dev->map_key, map_key_default, sizeof(map_key_default)); ANALYSIS SUMMARY: Hits = 2 Lines analyzed = 1503 in approximately 0.05 seconds (28168 lines/second) Physical Source Lines of Code (SLOC) = 1303 Hits@level = [0] 2 [1] 0 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 4 [1+] 2 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 3.06984 [1+] 1.53492 [2+] 1.53492 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
