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/haskell-hashtables-1.2.3.4/cbits/check.c Examining data/haskell-hashtables-1.2.3.4/cbits/common.c Examining data/haskell-hashtables-1.2.3.4/cbits/default.c Examining data/haskell-hashtables-1.2.3.4/cbits/defs.h Examining data/haskell-hashtables-1.2.3.4/cbits/sse-42-check.c Examining data/haskell-hashtables-1.2.3.4/cbits/sse-42.c FINAL RESULTS: data/haskell-hashtables-1.2.3.4/cbits/sse-42-check.c:10:5: [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 buf[256]; data/haskell-hashtables-1.2.3.4/cbits/sse-42-check.c:17:9: [2] (buffer) sprintf: Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or vsnprintf. Risk is low because the source has a constant maximum length. sprintf(buf, "fill-%x-%d-of-8", (int) v, i+1); \ ANALYSIS SUMMARY: Hits = 2 Lines analyzed = 716 in approximately 0.04 seconds (15955 lines/second) Physical Source Lines of Code (SLOC) = 594 Hits@level = [0] 5 [1] 0 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 7 [1+] 2 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 11.7845 [1+] 3.367 [2+] 3.367 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
