FINAL RESULTS:

data/kauth-5.74.0/src/kauthhelpersupport.cpp:27:9:  [4] (format) syslog:
  If syslog's format strings can be influenced by an attacker, they can be
  exploited (CWE-134). Use a constant format string for syslog.
#define syslog(level, ...) fprintf(stderr, __VA_ARGS__)
data/kauth-5.74.0/src/kauthhelpersupport.cpp:27:28:  [4] (format) fprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
#define syslog(level, ...) fprintf(stderr, __VA_ARGS__)
data/kauth-5.74.0/src/kauthhelpersupport.cpp:54:9:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
    if (getenv(home) == nullptr) {
data/kauth-5.74.0/examples/helper.cpp:34:15:  [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 (!file.open(QIODevice::ReadOnly)) {
data/kauth-5.74.0/autotests/TestHelper.cpp:50:18:  [1] (obsolete) usleep:
  This C routine is considered obsolete (as opposed to the shell command by
  the same name). The interaction of this function with SIGALRM and other
  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
  unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
        QThread::usleep(20000);
data/kauth-5.74.0/examples/helper.cpp:22:21:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
        ActionReply read(const QVariantMap& args);
data/kauth-5.74.0/examples/helper.cpp:29:23:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
ActionReply MyHelper::read(const QVariantMap& args)
data/kauth-5.74.0/examples/helper.cpp:60:17:  [1] (obsolete) usleep:
  This C routine is considered obsolete (as opposed to the shell command by
  the same name). The interaction of this function with SIGALRM and other
  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
  unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
       QThread::usleep(250000);
data/kauth-5.74.0/src/backends/dbus/DBusHelperProxy.cpp:273:52:  [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).
            if (strncmp(needle, method.typeName(), strlen(needle)) == 0) {
