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/pyrsistent-0.15.5/pvectorcmodule.c FINAL RESULTS: data/pyrsistent-0.15.5/pvectorcmodule.c:120:3: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy(result->items, source->items, sizeof(source->items)); data/pyrsistent-0.15.5/pvectorcmodule.c:563:3: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy(dest, src, BRANCH_FACTOR * sizeof(void*)); data/pyrsistent-0.15.5/pvectorcmodule.c:758:3: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy(newVec->tail->items, original->tail->items, TAIL_SIZE(original) * sizeof(void*)); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 1642 in approximately 0.06 seconds (25262 lines/second) Physical Source Lines of Code (SLOC) = 1249 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+] 2.40192 [1+] 2.40192 [2+] 2.40192 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
