Examining data/gamine-1.6/gamine.c

FINAL RESULTS:

data/gamine-1.6/gamine.c:282:21:  [3] (random) random:
  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.
        color.red = random() % 10 * 0.1;
data/gamine-1.6/gamine.c:283:23:  [3] (random) random:
  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.
        color.green = random() % 10 * 0.1;
data/gamine-1.6/gamine.c:284:22:  [3] (random) random:
  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.
        color.blue = random() % 10 * 0.1;
data/gamine-1.6/gamine.c:370:24:  [3] (random) random:
  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.
    star.spike_count = random() % 6 + 2;
data/gamine-1.6/gamine.c:398:32:  [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.
    dirname = g_build_filename(g_get_home_dir(), "gamine", NULL);
data/gamine-1.6/gamine.c:404:5:  [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(buf, "%d-%d-%d_%d-%d-%d.png", 1900 + t->tm_year,
