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/jack-delay-0.4.2/source/jack_delay.cc Examining data/jack-delay-0.4.2/source/mtdm.cc Examining data/jack-delay-0.4.2/source/mtdm.h FINAL RESULTS: data/jack-delay-0.4.2/source/jack_delay.cc:173:2: [4] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. sprintf (b, "%s:out", jack_name); data/jack-delay-0.4.2/source/jack_delay.cc:182:2: [4] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. sprintf (b, "%s:in", jack_name); data/jack-delay-0.4.2/source/jack_delay.cc:83:17: [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 ((k = getopt (ac, av, options)) != -1) data/jack-delay-0.4.2/source/jack_delay.cc:139:5: [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 b [1024]; data/jack-delay-0.4.2/source/jack_delay.cc:210:2: [1] (obsolete) usleep: This C routine is considered obsolete (as opposed to the shell command by the same name). The interaction of this function with SIGALRM and other timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead. usleep (250000); ANALYSIS SUMMARY: Hits = 5 Lines analyzed = 425 in approximately 0.06 seconds (6700 lines/second) Physical Source Lines of Code (SLOC) = 311 Hits@level = [0] 32 [1] 1 [2] 1 [3] 1 [4] 2 [5] 0 Hits@level+ = [0+] 37 [1+] 5 [2+] 4 [3+] 3 [4+] 2 [5+] 0 Hits/KSLOC@level+ = [0+] 118.971 [1+] 16.0772 [2+] 12.8617 [3+] 9.6463 [4+] 6.43087 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
