1.1 benno 229: <ul>
1.2 benno 230: <li>Add ability to constrain an RPKI Trust Anchor's effective signing
231: authority to a limited set of Internet numbers. This allows Relying
232: Parties to enjoy the potential benefits of assuming trust, but within
233: a bounded scope.
234: <li>Following a 'failed fetch' (described in RFC 9286), emit a warning and
235: continue with a previously cached Manifest file.
236: <li>Emit a warning when the remote repository presents a Manifest with an
237: unexpected manifestNumber.
238: <li>Improved CRL extension checking.
239: <li>Experimental support for the P-256 signature algorithm.
240: <!-- 8.8. -->
241: <li>A failed manifest fetch could result in a NULL pointer dereference or
242: a use after free.
243: <li>Reject non-conforming RRDP delta elements that contain neither publish
244: nor a withdraw element and fall back to the RRDP snapshot.
245: <li>Refactoring and minor bug fixes in the warning display functions.
246: <!-- 8.9 -->
247: <li>The handling of manifests fetched via rsync or RRDP was reworked to
248: fully conform to RFC 9286.
249: <li>Fix a race condition between closing an idle connection and scheduling a
250: new request on it.
251: <li>The evaluation time specified with -P now also applies to trust anchor
252: certificates.
253: <li>Check that the entire CMS eContent was consumed. Previously, trailing
254: data would be silently discarded on deserialization of products.
255: <li>In file mode do not consider overclaiming intermediate CA certificates
256: as invalid. OAA warning is still issued.
257: <li>Print the revocation time of certificates in file mode.
258: <li>Be more careful when converting OpenSSL numeric identifiers (NIDs)
259: to strings.
260: <!-- 9.0 -->
261: <li>Added support for RPKI Signed Prefix Lists.
262: <li>Added an -x flag to opt into parsing and evaluation of file types that are
263: still considered experimental.
264: <li>Added a metric to track the number of new files that were moved to the
265: validated cache.
266: <li>Ensure that the FileAndHashes list in a Manifest contains no duplicate
267: file names and no duplicate hashes.
1.1 benno 268: </ul>

1.5 op 272: <li>Add <code>Message-Id</code> as needed for messages received on
273: the submission port.
274: <li>Added support for RFC 7505 "Null MX" handling and treat
275: an MX of "localhost" as it were a "Null MX".
276: <li>Allow inline tables and filter listings in
277: <a href="https://man.openbsd.org/smtpd.conf.5">smtpd.conf(5)</a>
278: to span over multiple lines.
279: <li>Enabled <abbr title="Delivery Status Notification">DSN</abbr>
280: for the implicit socket too.
281: <li>Added the
282: <a href="https://man.openbsd.org/smtpd.conf.5#no-dsn~2">no-dsn</a>
283: option for <code>listen on socket</code> too.

290: <li>Disallow custom commands and file reading in root's
291: <code>.forward</code> file.
292: <li>Do not process other users <code>.forward</code> files when
293: an alternate delivery user is provided in a dispatcher.
294: <li>Unify the <a href="https://man.openbsd.org/table.5">table(5)</a>
295: parser used in
296: <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a> and
297: <a href="https://man.openbsd.org/makemap.8">makemap(8)</a>.

1.16 djm 422: <li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>, <a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: implement protocol extensions to thwart the
423: so-called "Terrapin attack" discovered by Fabian Bäumer, Marcus
424: Brinkmann and Jörg Schwenk. This attack allows a MITM to effect a
425: limited break of the integrity of the early encrypted SSH transport
426: protocol by sending extra messages prior to the commencement of
427: encryption, and deleting an equal number of consecutive messages
428: immediately after encryption starts. A peer SSH client/server
429: would not be able to detect that messages were deleted.
430:
431: <br>While cryptographically novel, the security impact of this attack
432: is fortunately very limited as it only allows deletion of
433: consecutive messages, and deleting most messages at this stage of
1.17 gnezdo 434: the protocol prevents user authentication from proceeding and
1.16 djm 435: results in a stuck connection.
436:
437: <br>The most serious identified impact is that it lets a MITM to
438: delete the SSH2_MSG_EXT_INFO message sent before authentication
439: starts, allowing the attacker to disable a subset of the keystroke
440: timing obfuscation features introduced in OpenSSH 9.5. There is no
441: other discernable impact to session secrecy or session integrity.
442:
443: <li><a href='https://man.openbsd.org/ssh-agent.1'>ssh-agent(1)</a>: when adding PKCS#11-hosted private keys while
444: specifying destination constraints, if the PKCS#11 token returned
445: multiple keys then only the first key had the constraints applied.
446: Use of regular private keys, FIDO tokens and unconstrained keys
447: are unaffected.
448:
449: <li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: if an invalid user or hostname that contained shell
450: metacharacters was passed to <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>, and a ProxyCommand,
451: LocalCommand directive or "match exec" predicate referenced the
452: user or hostname via %u, %h or similar expansion token, then
453: an attacker who could supply arbitrary user/hostnames to <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>
454: could potentially perform command injection depending on what
455: quoting was present in the user-supplied <a href='https://man.openbsd.org/ssh_config.5'>ssh_config(5)</a> directive.
456:
457: <br>OpenSSH 9.6 now
458: bans most shell metacharacters from user and hostnames supplied
459: via the command-line. This countermeasure is not guaranteed to be
460: effective in all situations, as it is infeasible for <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a> to
461: universally filter shell metacharacters potentially relevant to
462: user-supplied commands.
463:
464: <br>User/hostnames provided via <a href='https://man.openbsd.org/ssh_config.5'>ssh_config(5)</a> are not subject to these
465: restrictions, allowing configurations that use strange names to
466: continue to be used, under the assumption that the user knows what
467: they are doing in their own configuration files.

1.16 djm 471: <li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>, <a href='https://man.openbsd.org/sshd.8'>sshd(8)</a>: add a "global" ChannelTimeout type that watches
472: all open channels and will close all open channels if there is no
473: traffic on any of them for the specified interval. This is in
474: addition to the existing per-channel timeouts added recently.
475: <br>This supports situations like having both session and x11
476: forwarding channels open where one may be idle for an extended
477: period but the other is actively used. The global timeout could
478: close both channels when both have been idle for too long.

829: <h3>Ports Tree</h3>
830: <p>
831: A ports tree archive is also provided. To extract:
832: <blockquote><pre>
833: # <kbd>cd /usr</kbd>
834: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
835: </pre></blockquote>
836: <p>
837: Go read the <a href="faq/ports/index.html">ports</a> page
838: if you know nothing about ports
839: at this point. This text is not a manual of how to use ports.
840: Rather, it is a set of notes meant to kickstart the user on the
841: OpenBSD ports system.
842: <p>
843: The <i>ports/</i> directory represents a CVS checkout of our ports.
844: As with our complete source tree, our ports tree is available via
845: <a href="anoncvs.html">AnonCVS</a>.
846: So, in order to keep up to date with the -stable branch, you must make
847: the <i>ports/</i> tree available on a read-write medium and update the tree
848: with a command like:
849: <blockquote><pre>
850: # <kbd>cd /usr/ports</kbd>
851: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_5</kbd>
852: </pre></blockquote>
853: <p>
854: [Of course, you must replace the server name here with a nearby anoncvs
855: server.]
856: <p>
857: Note that most ports are available as packages on our mirrors. Updated
858: ports for the 7.5 release will be made available if problems arise.
859: <p>
860: If you're interested in seeing a port added, would like to help out, or just
861: would like to know more, the mailing list
862: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
