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/ros-resource-retriever-1.12.6/include/resource_retriever/retriever.h Examining data/ros-resource-retriever-1.12.6/src/retriever.cpp Examining data/ros-resource-retriever-1.12.6/test/test.cpp FINAL RESULTS: data/ros-resource-retriever-1.12.6/src/retriever.cpp:93:3: [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(&membuf->v[prev_size], buffer, size * nmemb); data/ros-resource-retriever-1.12.6/src/retriever.cpp:125:3: [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 error_buffer[CURL_ERROR_SIZE]; data/ros-resource-retriever-1.12.6/src/retriever.cpp:141:5: [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(res.data.get(), &buf.v[0], res.size); data/ros-resource-retriever-1.12.6/test/test.cpp:65:15: [2] (misc) fopen: 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). FILE* f = fopen(path.c_str(), "w"); data/ros-resource-retriever-1.12.6/src/retriever.cpp:103:22: [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). mod_url.erase(0, strlen("package://")); ANALYSIS SUMMARY: Hits = 5 Lines analyzed = 378 in approximately 0.03 seconds (12777 lines/second) Physical Source Lines of Code (SLOC) = 224 Hits@level = [0] 1 [1] 1 [2] 4 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 6 [1+] 5 [2+] 4 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 26.7857 [1+] 22.3214 [2+] 17.8571 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
