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/py3c-1.2/include/py3c.h Examining data/py3c-1.2/include/py3c/capsulethunk.h Examining data/py3c-1.2/include/py3c/comparison.h Examining data/py3c-1.2/include/py3c/compat.h Examining data/py3c-1.2/include/py3c/fileshim.h Examining data/py3c-1.2/include/py3c/py3shims.h Examining data/py3c-1.2/include/py3c/tpflags.h Examining data/py3c-1.2/test/test_py3c.c FINAL RESULTS: data/py3c-1.2/include/py3c/capsulethunk.h:90:5: [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(name_dup, name, name_length); data/py3c-1.2/test/test_py3c.c:290:2: [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 data[200]; data/py3c-1.2/include/py3c/capsulethunk.h:83:27: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). size_t name_length = (strlen(name) + 1) * sizeof(char); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 1177 in approximately 0.04 seconds (29743 lines/second) Physical Source Lines of Code (SLOC) = 864 Hits@level = [0] 1 [1] 1 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 4 [1+] 3 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 4.62963 [1+] 3.47222 [2+] 2.31481 [3+] 0 [4+] 0 [5+] 0 Symlinks skipped = 1 (--allowlink overrides but see doc for security issue) Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
