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/oggfwd-0.2/oggfwd.c FINAL RESULTS: data/oggfwd-0.2/oggfwd.c:116:15: [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 ((ch = getopt(argc, argv, "d:g:hn:pu:")) != -1) { data/oggfwd-0.2/oggfwd.c:106:11: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. unsigned char buff[BUFFERSIZE]; data/oggfwd-0.2/oggfwd.c:87:8: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). siz = strlen(opt) + 1; ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 241 in approximately 0.02 seconds (15218 lines/second) Physical Source Lines of Code (SLOC) = 189 Hits@level = [0] 19 [1] 1 [2] 1 [3] 1 [4] 0 [5] 0 Hits@level+ = [0+] 22 [1+] 3 [2+] 2 [3+] 1 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 116.402 [1+] 15.873 [2+] 10.582 [3+] 5.29101 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
