FINAL RESULTS:

data/ristretto-0.10.0/src/file.c:576:63:  [3] (buffer) g_get_home_dir:
  This function is synonymous with 'getenv("HOME")';it returns untrustable
  input if the environment can beset by an attacker. It 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.
            r_file->priv->thumbnail_path = g_build_path ("/", g_get_home_dir(), ".thumbnails", "normal", filename, NULL);
data/ristretto-0.10.0/src/image_list.c:322:31:  [3] (random) g_random_int:
  This function is not sufficiently random for security-related functions
  such as key and nonce creation (CWE-327). Use a more secure technique for
  acquiring random values.
    image_list->priv->stamp = g_random_int();
data/ristretto-0.10.0/src/properties_dialog.c:346:49:  [3] (buffer) g_get_home_dir:
  This function is synonymous with 'getenv("HOME")';it returns untrustable
  input if the environment can beset by an attacker. It can have any content

data/ristretto-0.10.0/src/file.c:565:72:  [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).
        checksum = g_compute_checksum_for_string (G_CHECKSUM_MD5, uri, strlen (uri));
data/ristretto-0.10.0/src/main_window.c:3234:13:  [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 (strlen (g_value_get_string (&current_uri_val)) > 0)
data/ristretto-0.10.0/src/properties_dialog.c:335:86:  [1] (buffer) strlen:
