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/bchunk-1.2.2/bchunk.c FINAL RESULTS: data/bchunk-1.2.2/bchunk.c:107:14: [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 ((s = getopt(argc, argv, "swvp?hr")) != -1) { data/bchunk-1.2.2/bchunk.c:167:9: [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). mins = atoi(s); data/bchunk-1.2.2/bchunk.c:173:9: [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). secs = atoi(p); data/bchunk-1.2.2/bchunk.c:176:11: [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). frames = atoi(t); data/bchunk-1.2.2/bchunk.c:245:9: [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. static char s[80]; data/bchunk-1.2.2/bchunk.c:268:2: [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 buf[SECTLEN+10]; data/bchunk-1.2.2/bchunk.c:282:12: [2] (misc) fopen: 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). if (!(f = fopen(fname, "w"))) { data/bchunk-1.2.2/bchunk.c:388:2: [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 s[CUELLEN+1]; data/bchunk-1.2.2/bchunk.c:401:16: [2] (misc) fopen: 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). if (!((cuef = fopen(cuefile, "r")))) { data/bchunk-1.2.2/bchunk.c:444:17: [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). track->num = atoi(p); ANALYSIS SUMMARY: Hits = 11 Lines analyzed = 500 in approximately 0.05 seconds (10891 lines/second) Physical Source Lines of Code (SLOC) = 376 Hits@level = [0] 37 [1] 0 [2] 10 [3] 1 [4] 0 [5] 0 Hits@level+ = [0+] 48 [1+] 11 [2+] 11 [3+] 1 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 127.66 [1+] 29.2553 [2+] 29.2553 [3+] 2.65957 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
