data/qmidiroute-0.4.0/src/logwidget.cpp:68:16:  [4] (format) sprintf:
  Potential format string problem (CWE-134). Make format string constant.

data/qmidiroute-0.4.0/src/main.cpp:59:28:  [4] (shell) system:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
    QLocale loc = QLocale::system();
data/qmidiroute-0.4.0/src/main.cpp:29:29:  [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 ((getopt_return = getopt_long(argc, argv, "vhp:", options,
data/qmidiroute-0.4.0/src/main.cpp:33:29:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
                portCount = atoi(optarg);
data/qmidiroute-0.4.0/src/mainwindow.cpp:402:12:  [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).
    if (!f.open(QIODevice::ReadOnly)) {

    if (!f.open(QIODevice::WriteOnly)) {
data/qmidiroute-0.4.0/src/seqdriver.cpp:42:5:  [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 buf[16];
data/qmidiroute-0.4.0/src/mainwindow.cpp:576:9:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    if (read(fd, &message, sizeof(message)) == -1) {
