FINAL RESULTS:
data/codecrypt-1.8/src/privfile.cpp:53:8: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
if (chmod (fn.c_str(), st.st_mode & ~07))
data/codecrypt-1.8/src/privfile.cpp:58:6: [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.
if (access (fn.c_str(), R_OK | W_OK)) return false;
data/codecrypt-1.8/src/pwrng.cpp:53:15: [4] (misc) getpass:
This function is obsolete and not portable. It was in SUSv2 but removed by
POSIX.2. What it does exactly varies considerably between systems,
particularly in where its prompt is displayed and where it gets its data
(e.g., /dev/tty, stdin, stderr, etc.). In addition, some implementations
overflow buffers. (CWE-676, CWE-120, CWE-20). Make the specific calls to do
exactly what you want. If you continue to use it, or write your own, be
sure to zero the password as soon as possible to avoid leaving the
cleartext password visible in the process' address space.
char* pass = getpass (prompt.c_str());
data/codecrypt-1.8/src/algos_enc.cpp:129:27: [3] (random) random:

such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.

data/codecrypt-1.8/src/generator.cpp:43:21: [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.

data/codecrypt-1.8/src/main.cpp:204:7: [3] (buffer) getopt_long:
Some older implementations do not protect against internal buffer overflows
(CWE-120, CWE-20). Check implementation on installation, or limit the size
of all string inputs.

data/codecrypt-1.8/src/main.cpp:338:16: [3] (buffer) getenv:
