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/aconnectgui-0.9.0rc2-1/src/Client.cxx Examining data/aconnectgui-0.9.0rc2-1/src/Connector.cxx Examining data/aconnectgui-0.9.0rc2-1/src/Layout.H Examining data/aconnectgui-0.9.0rc2-1/src/Port.cxx Examining data/aconnectgui-0.9.0rc2-1/src/Connection.cxx Examining data/aconnectgui-0.9.0rc2-1/src/Window.cxx Examining data/aconnectgui-0.9.0rc2-1/src/aconnect.cxx FINAL RESULTS: data/aconnectgui-0.9.0rc2-1/src/aconnect.cxx:44:2: [4] (format) vfprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. vfprintf(stderr, fmt, arg); data/aconnectgui-0.9.0rc2-1/src/aconnect.cxx:329:14: [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. while ((c = getopt_long(argc, argv, "dior:t:elx", long_option, NULL)) != -1) { data/aconnectgui-0.9.0rc2-1/src/Window.cxx:136:2: [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 from[16]; data/aconnectgui-0.9.0rc2-1/src/Window.cxx:137:2: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).
