Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/apt-move-4.2.27/fetch.cc FINAL RESULTS: data/apt-move-4.2.27/fetch.cc:111:14: [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 ((c = getopt(argc, argv, "t")) != -1) { ANALYSIS SUMMARY: Hits = 1 Lines analyzed = 139 in approximately 0.01 seconds (10050 lines/second) Physical Source Lines of Code (SLOC) = 119 Hits@level = [0] 0 [1] 0 [2] 0 [3] 1 [4] 0 [5] 0 Hits@level+ = [0+] 1 [1+] 1 [2+] 1 [3+] 1 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 8.40336 [1+] 8.40336 [2+] 8.40336 [3+] 8.40336 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
