data/mcrypt-2.6.8/src/defines.h:167:14: [4] (crypto) crypt:
The crypt functions use a poor one-way hashing algorithm; since they only
accept passwords of 8 characters or fewer and only a two-byte salt, they
are excessively vulnerable to dictionary attacks given today's faster
computing equipment (CWE-327). Use a different algorithm, such as SHA-256,
with a larger, non-repeating salt.
extern char *crypt(); /* libufc */
data/mcrypt-2.6.8/src/extra.c:33:26: [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This function is obsolete and not portable.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.

execl(entry->path, entry->path, entry->arg, NULL);
data/mcrypt-2.6.8/src/rndunix.c:498:6: [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.
