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/python-pyeclib-1.6.0/src/c/pyeclib_c/capsulethunk.h Examining data/python-pyeclib-1.6.0/src/c/pyeclib_c/pyeclib_c.c Examining data/python-pyeclib-1.6.0/src/c/pyeclib_c/pyeclib_c.h FINAL RESULTS: data/python-pyeclib-1.6.0/src/c/pyeclib_c/capsulethunk.h:109:5: [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/python-pyeclib-1.6.0/src/c/pyeclib_c/pyeclib_c.c:147:5: [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 err[255]; data/python-pyeclib-1.6.0/src/c/pyeclib_c/pyeclib_c.c:994:24: [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. hex_encoded_ptr += sprintf(hex_encoded_ptr, "%.2x", (unsigned char)buf[i]); data/python-pyeclib-1.6.0/src/c/pyeclib_c/capsulethunk.h:102:27: [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 = 4 Lines analyzed = 1446 in approximately 0.06 seconds (24480 lines/second) Physical Source Lines of Code (SLOC) = 980 Hits@level = [0] 1 [1] 1 [2] 3 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 5 [1+] 4 [2+] 3 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 5.10204 [1+] 4.08163 [2+] 3.06122 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
