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/cbm-0.2/src/ErrnoError.hpp Examining data/cbm-0.2/src/cbm.cpp Examining data/cbm-0.2/src/statistics.cpp Examining data/cbm-0.2/src/statistics.hpp Examining data/cbm-0.2/src/widgets/Bar.cpp Examining data/cbm-0.2/src/widgets/Bar.hpp Examining data/cbm-0.2/src/widgets/CursesError.hpp Examining data/cbm-0.2/src/widgets/Screen.cpp Examining data/cbm-0.2/src/widgets/Screen.hpp Examining data/cbm-0.2/src/widgets/VerticalTable.cpp Examining data/cbm-0.2/src/widgets/VerticalTable.hpp Examining data/cbm-0.2/src/widgets/Window.cpp Examining data/cbm-0.2/src/widgets/Window.hpp FINAL RESULTS: data/cbm-0.2/src/cbm.cpp:298:4: [4] (buffer) strcpy: Does not check for buffer overflows when copying to destination [MS-banned] (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused). strcpy(req.ifr_name, interface->getName().c_str()); data/cbm-0.2/src/cbm.cpp:120:15: [3] (buffer) getopt_long: Some older implementations do not protect against internal buffer overflows (CWE-120, CWE-20). Check implementation on installation, or limit the size of all string inputs. int ch = getopt_long(argc, argv, "", longopts, NULL); data/cbm-0.2/src/cbm.cpp:303:8: [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 addrString[100]; data/cbm-0.2/src/statistics.cpp:58:5: [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(statistics_ + 1, statistics_ + 0, sizeof(Statistics)); data/cbm-0.2/src/statistics.cpp:59:5: [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(statistics_, &statistics, sizeof(Statistics)); data/cbm-0.2/src/statistics.cpp:76:17: [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 *dev = fopen(PROC_NET_DEV, "r"); data/cbm-0.2/src/statistics.cpp:88:6: [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 buf[500]; ANALYSIS SUMMARY: Hits = 7 Lines analyzed = 1114 in approximately 0.31 seconds (3558 lines/second) Physical Source Lines of Code (SLOC) = 665 Hits@level = [0] 1 [1] 0 [2] 5 [3] 1 [4] 1 [5] 0 Hits@level+ = [0+] 8 [1+] 7 [2+] 7 [3+] 2 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 12.0301 [1+] 10.5263 [2+] 10.5263 [3+] 3.00752 [4+] 1.50376 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
