FINAL RESULTS:

data/light-locker-1.8.0/src/gs-listener-dbus.c:2297:41:  [4] (race) access:
  This usually indicates a security flaw. If an attacker can change anything
  along the path between the call to access() and the file's actual use
  (e.g., by moving files), the attacker can exploit the race condition
  (CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
  and try to open the file directly.
        listener->priv->have_systemd = (access("/run/systemd/seats/", F_OK) >= 0);
data/light-locker-1.8.0/src/gs-bus.h:53:41:  [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.
#define DM_SESSION_PATH                 getenv("XDG_SESSION_PATH")
data/light-locker-1.8.0/src/gs-listener-dbus.c:2204:58:  [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.
                listener->priv->sd_session_id = g_strdup(getenv("XDG_SESSION_ID"));
data/light-locker-1.8.0/src/gs-debug.c:51:9:  [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    buffer [1025];
data/light-locker-1.8.0/src/gs-debug.c:96:23:  [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.
                const char path [50] = "light_locker_debug_XXXXXX";
data/light-locker-1.8.0/src/gs-grab-x11.c:74:32:  [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.
                        static char foo [255];
data/light-locker-1.8.0/src/gs-grab-x11.c:75:25:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
                        sprintf (foo, "unknown status: %d", status);
data/light-locker-1.8.0/src/gs-listener-dbus.c:599:9:  [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.
