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/setop-0.1/src/main.cpp FINAL RESULTS: data/setop-0.1/src/main.cpp:144:13: [2] (misc) open: 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). inputfile.open(filename); data/setop-0.1/src/main.cpp:46:47: [1] (buffer) equal: Function does not check the second iterator for over-read conditions (CWE-126). This function is often discouraged by most C++ coding standards in favor of its safer alternatives provided since C++14. Consider using a form of this function that checks the second iterator before potentially overflowing it. #error Macro EXIT_QUERY_NEGATIVE must not be equal to EXIT_SUCCESS or to EXIT_FAILURE. data/setop-0.1/src/main.cpp:215:15: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). inputstream.read(buffer.get() + used_buffer, buffersize - used_buffer); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 631 in approximately 0.03 seconds (21561 lines/second) Physical Source Lines of Code (SLOC) = 425 Hits@level = [0] 0 [1] 2 [2] 1 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 3 [1+] 3 [2+] 1 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 7.05882 [1+] 7.05882 [2+] 2.35294 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
