NOTE. FreeBSD uses both a different PAM implementation and a different PAM support in OpenSSH: it doesn't seem to be vulnerable to this particular timing leak issue. All OpenSSH-portable releases <= OpenSSH_3.6.1p1 compiled with PAM support enabled (./configure --with-pam) are vulnerable to this information leak. The PAMAuthenticationViaKbdInt directive doesn't need to be enabled in sshd_config.
Howevever, it lists MACOSX as "unconfirmed". I thought MACOSX used the FreeBSD ssh implementation.
