FINAL RESULTS:
data/atomix-3.34.0/src/level-manager.c:204:32: [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.
dir_path = g_build_filename (g_get_home_dir (), ".atomix", "level", NULL);
data/atomix-3.34.0/src/playfield.c:651:10: [3] (random) g_random_int_range:
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.
row = g_random_int_range (min_wall[0], max_wall[0]);
