Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/jnoise-0.6.0/source/jnoise.cc Examining data/jnoise-0.6.0/source/prbsgen.h Examining data/jnoise-0.6.0/source/rngen.cc Examining data/jnoise-0.6.0/source/rngen.h FINAL RESULTS: data/jnoise-0.6.0/source/jnoise.cc:115:15: [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. while (1) usleep (200000); ANALYSIS SUMMARY: Hits = 1 Lines analyzed = 606 in approximately 0.10 seconds (5927 lines/second) Physical Source Lines of Code (SLOC) = 334 Hits@level = [0] 3 [1] 1 [2] 0 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 4 [1+] 1 [2+] 0 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 11.976 [1+] 2.99401 [2+] 0 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
