FreeBSD : FreeBSD -- pam_ssh improperly grants access when user account has unencrypted SSH private keys (eda151d8-4638-11e1-9f47-00e0815b8da8)

Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

The OpenSSL library call used to decrypt private keys ignores the
passphrase argument if the key is not encrypted. Because the pam_ssh
module only checks whether the passphrase provided by the user is
null, users with unencrypted SSH private keys may successfully
authenticate themselves by providing a dummy passphrase.
