FINAL RESULTS:
data/openvpn-auth-ldap-2.0.4/src/testplugin.c:84:16: [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This function is obsolete and not portable.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.
password = getpass("Password: ");
data/openvpn-auth-ldap-2.0.4/src/testplugin.c:91:5: [4] (buffer) strcpy:

(e.g., by moving files), the attacker can exploit the race condition
