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/conda-package-handling-1.7.2/src/conda_package_handling/archive_utils_c.c FINAL RESULTS: data/conda-package-handling-1.7.2/src/conda_package_handling/archive_utils_c.c:77:5: [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 buff[8192]; data/conda-package-handling-1.7.2/src/conda_package_handling/archive_utils_c.c:107:10: [2] (misc) open: 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). fd = open(filename, O_RDONLY | O_BINARY); data/conda-package-handling-1.7.2/src/conda_package_handling/archive_utils_c.c:108:11: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). len = read(fd, buff, sizeof(buff)); data/conda-package-handling-1.7.2/src/conda_package_handling/archive_utils_c.c:111:15: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). len = read(fd, buff, sizeof(buff)); ANALYSIS SUMMARY: Hits = 4 Lines analyzed = 207 in approximately 0.11 seconds (1804 lines/second) Physical Source Lines of Code (SLOC) = 190 Hits@level = [0] 0 [1] 2 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 4 [1+] 4 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 21.0526 [1+] 21.0526 [2+] 10.5263 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 3 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
