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/yatm-0.9/yatm.cc FINAL RESULTS: data/yatm-0.9/yatm.cc:757:4: [4] (format) fprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. fprintf(stderr, header->vbr ? ", VBR)\n" : ")\n"); data/yatm-0.9/yatm.cc:180:15: [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 ((c = getopt(argc, argv, "b:e:c:s:qt:vVh")) != -1) { data/yatm-0.9/yatm.cc:149:3: [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. char buffer[bufsize * channels * sizeof(signed int)]; data/yatm-0.9/yatm.cc:189:24: [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). pitchCentDelta = atoi(optarg); data/yatm-0.9/yatm.cc:192:24: [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). pitchCentDelta = atoi(optarg)*100; data/yatm-0.9/yatm.cc:227:12: [2] (misc) open: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents? (CWE-362). int fd = open(input_file, O_RDONLY); ANALYSIS SUMMARY: Hits = 6 Lines analyzed = 934 in approximately 0.04 seconds (22764 lines/second) Physical Source Lines of Code (SLOC) = 761 Hits@level = [0] 40 [1] 0 [2] 4 [3] 1 [4] 1 [5] 0 Hits@level+ = [0+] 46 [1+] 6 [2+] 6 [3+] 2 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 60.4468 [1+] 7.88436 [2+] 7.88436 [3+] 2.62812 [4+] 1.31406 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
