FINAL RESULTS:
data/tetzle-2.1.6/src/generator.cpp:57:59: [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.
Generator::Generator(int columns, int rows, std::mt19937& random) :

data/tetzle-2.1.6/src/path.cpp:54:12: [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.
oldpath = getenv("$XDG_DATA_HOME");
data/tetzle-2.1.6/src/board.cpp:279:12: [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(QFile::ReadOnly)) {
data/tetzle-2.1.6/src/graphics_layer.h:43:11: [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.
unsigned char pad[4];
