The telnetd codebase is unmaintained and has a number of quality
issues. Telnet has been largely supplanted by ssh. If needed, a port is
available (net/freebsd-telnetd), but a more maintained implementation
should be prefered.
While the telnet client suffers from the same issues, it is deemed
to be of lower risk and is required to connect to legacy devices, so
it remains.

According to pam_exec(8), the `expose_authtok` option should be ignored
when the service function is `pam_sm_setcred`. Currently `pam_exec` only
prevent prompt for anth token when `expose_authtok` is set on
`pam_sm_setcred`. This subsequently led to segfault when there isn't an
existing auth token available.
Bug reported on this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263893
After reading https://reviews.freebsd.org/rS349556 I am not sure if the
default behaviour supposed to be simply not prompt for authentication
token, or is it to ignore the option entirely as stated in the man page.
This patch is therefore only adding an additional NULL check on the item
`pam_get_item` provide, and exit with `PAM_SYSTEM_ERR` when such item is
NULL.

Release notes are available at https://www.openssh.com/txt/release-8.9
Some highlights:
* ssh(1), sshd(8), ssh-add(1), ssh-agent(1): add a system for
restricting forwarding and use of keys added to ssh-agent(1)
* ssh(1), sshd(8): add the sntrup761x25519-sha512@openssh.com hybrid
ECDH/x25519 + Streamlined NTRU Prime post-quantum KEX to the
default KEXAlgorithms list (after the ECDH methods but before the
prime-group DH ones). The next release of OpenSSH is likely to
make this key exchange the default method.
* sshd(8), portable OpenSSH only: this release removes in-built
support for MD5-hashed passwords. If you require these on your
system then we recommend linking against libxcrypt or similar.
Future deprecation notice
=========================
A near-future release of OpenSSH will switch scp(1) from using the
legacy scp/rcp protocol to using SFTP by default.
Legacy scp/rcp performs wildcard expansion of remote filenames (e.g.
"scp host:* .") through the remote shell. This has the side effect of
requiring double quoting of shell meta-characters in file names
included on scp(1) command-lines, otherwise they could be interpreted
as shell commands on the remote side.

Some notable changes, from upstream's release notes:
- sshd(8): Remove support for obsolete "host/port" syntax.
- ssh(1): When prompting whether to record a new host key, accept the key
fingerprint as a synonym for "yes".
- ssh-keygen(1): when acting as a CA and signing certificates with an RSA
key, default to using the rsa-sha2-512 signature algorithm.
- ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
(RSA/SHA1) algorithm from those accepted for certificate signatures.
- ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F
support to provide address-space isolation for token middleware
libraries (including the internal one).
- ssh(1): this release enables UpdateHostkeys by default subject to some
conservative preconditions.
- scp(1): this release changes the behaviour of remote to remote copies
(e.g. "scp host-a:/path host-b:") to transfer through the local host
by default.
- scp(1): experimental support for transfers using the SFTP protocol as
a replacement for the venerable SCP/RCP protocol that it has
traditionally used.
Additional integration work is needed to support FIDO/U2F in the base
system.
Deprecation Notice
------------------
OpenSSH will disable the ssh-rsa signature scheme by default in the
next release.

up to par with the Linux pam_access(8).
Like the Linux pam_access(8) our pam_login_access(8) is a service module
for pam(3) that allows a administrator to limit access from specified
remote hosts or terminals. Unlike the Linux pam_access, pam_login_access
is missing some features which are added by this commit:
Access file can now be specified. The default remains /etc/access.conf.
The syntax is consistent with Linux pam_access.
By default usernames are matched. If the username fails to match a match
against a group name is attempted. The new nodefgroup module option will
only match a username and no attempt to match a group name is made.
Group names must be specified in brackets, "()" when nodefgroup is
specified. Otherwise the old backward compatible behavior is used.
This is consistent with Linux pam_access.
A new field separator module option allows the replacement of the default
colon (:) with any other character. This facilitates potential future
specification of X displays. This is also consistent with Linux pam_access.
A new list separator module option to replace the default space/comma/tab
with another character. This too is consistent with Linux pam_access.
Linux pam_access options not implemented in this commit are the debug
and audit options. These will be implemented at a later date.
