Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char buffer[length]; ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 497 in approximately 1.86 seconds (267 lines/second) Physical Source Lines of Code (SLOC) = 305 Hits@level = [0] 0 [1] 0 [2] 3 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 3 [1+] 3 [2+] 3 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 9.83607 [1+] 9.83607 [2+] 9.83607 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 2 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
