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/mbw-1.2.2/mbw.c FINAL RESULTS: data/mbw-1.2.2/mbw.c:186:14: [3] (buffer) getopt: Some older implementations do not protect against internal buffer overflows (CWE-120, CWE-20). Check implementation on installation, or limit the size of all string inputs. while((o=getopt(argc, argv, "haqn:t:b:")) != EOF) { data/mbw-1.2.2/mbw.c:104:9: [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(b, a, array_bytes); ANALYSIS SUMMARY: Hits = 2 Lines analyzed = 287 in approximately 0.02 seconds (17285 lines/second) Physical Source Lines of Code (SLOC) = 196 Hits@level = [0] 29 [1] 0 [2] 1 [3] 1 [4] 0 [5] 0 Hits@level+ = [0+] 31 [1+] 2 [2+] 2 [3+] 1 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 158.163 [1+] 10.2041 [2+] 10.2041 [3+] 5.10204 [4+] 0 [5+] 0 Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
