Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char buf[51]; data/bastet-0.43/Ui.cpp:477:2: [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(500000/6); ANALYSIS SUMMARY: Hits = 15 Lines analyzed = 1992 in approximately 0.06 seconds (33387 lines/second) Physical Source Lines of Code (SLOC) = 1402 Hits@level = [0] 2 [1] 1 [2] 1 [3] 13 [4] 0 [5] 0 Hits@level+ = [0+] 17 [1+] 15 [2+] 14 [3+] 13 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 12.1255 [1+] 10.699 [2+] 9.98573 [3+] 9.27247 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
