583: so-called "Terrapin attack" discovered by Fabian Bäumer, Marcus
584: Brinkmann and Jörg Schwenk. This attack allows a MITM to effect a
585: limited break of the integrity of the early encrypted SSH transport
586: protocol by sending extra messages prior to the commencement of
587: encryption, and deleting an equal number of consecutive messages
588: immediately after encryption starts. A peer SSH client/server
589: would not be able to detect that messages were deleted.
590:
591: <br>While cryptographically novel, the security impact of this attack
592: is fortunately very limited as it only allows deletion of
593: consecutive messages, and deleting most messages at this stage of
1.17 gnezdo 594: the protocol prevents user authentication from proceeding and
1.16 djm 595: results in a stuck connection.
596:
597: <br>The most serious identified impact is that it lets a MITM to
598: delete the SSH2_MSG_EXT_INFO message sent before authentication
599: starts, allowing the attacker to disable a subset of the keystroke
600: timing obfuscation features introduced in OpenSSH 9.5. There is no
601: other discernable impact to session secrecy or session integrity.
602:
603: <li><a href='https://man.openbsd.org/ssh-agent.1'>ssh-agent(1)</a>: when adding PKCS#11-hosted private keys while
604: specifying destination constraints, if the PKCS#11 token returned
605: multiple keys then only the first key had the constraints applied.
606: Use of regular private keys, FIDO tokens and unconstrained keys
607: are unaffected.
608:
609: <li><a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>: if an invalid user or hostname that contained shell
610: metacharacters was passed to <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>, and a ProxyCommand,
611: LocalCommand directive or "match exec" predicate referenced the
612: user or hostname via %u, %h or similar expansion token, then
613: an attacker who could supply arbitrary user/hostnames to <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a>
614: could potentially perform command injection depending on what
615: quoting was present in the user-supplied <a href='https://man.openbsd.org/ssh_config.5'>ssh_config(5)</a> directive.
616:
617: <br>OpenSSH 9.6 now
618: bans most shell metacharacters from user and hostnames supplied
619: via the command-line. This countermeasure is not guaranteed to be
620: effective in all situations, as it is infeasible for <a href='https://man.openbsd.org/ssh.1'>ssh(1)</a> to
621: universally filter shell metacharacters potentially relevant to
622: user-supplied commands.
623:
624: <br>User/hostnames provided via <a href='https://man.openbsd.org/ssh_config.5'>ssh_config(5)</a> are not subject to these
625: restrictions, allowing configurations that use strange names to

635: <br>This supports situations like having both session and x11

949: If you already have an OpenBSD 7.4 system, and do not want to reinstall,

957: <h3>Notes about the source code</h3>
958: <p>
959: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
960: This file contains everything you need except for the kernel sources,
961: which are in a separate archive.
962: To extract:
963: <blockquote><pre>
964: # <kbd>mkdir -p /usr/src</kbd>
965: # <kbd>cd /usr/src</kbd>
966: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
967: </pre></blockquote>
968: <p>
969: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
970: This file contains all the kernel sources you need to rebuild kernels.
971: To extract:
972: <blockquote><pre>
973: # <kbd>mkdir -p /usr/src/sys</kbd>
974: # <kbd>cd /usr/src</kbd>
975: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
976: </pre></blockquote>
977: <p>
978: Both of these trees are a regular CVS checkout. Using these trees it
979: is possible to get a head-start on using the anoncvs servers as
980: described <a href="anoncvs.html">here</a>.
981: Using these files
982: results in a much faster initial CVS update than you could expect from
983: a fresh checkout of the full OpenBSD source tree.

989: <h3>Ports Tree</h3>
990: <p>
991: A ports tree archive is also provided. To extract:
992: <blockquote><pre>
993: # <kbd>cd /usr</kbd>
994: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
995: </pre></blockquote>
996: <p>
997: Go read the <a href="faq/ports/index.html">ports</a> page
998: if you know nothing about ports
999: at this point. This text is not a manual of how to use ports.
1000: Rather, it is a set of notes meant to kickstart the user on the
1001: OpenBSD ports system.
1002: <p>
1003: The <i>ports/</i> directory represents a CVS checkout of our ports.
1004: As with our complete source tree, our ports tree is available via
1005: <a href="anoncvs.html">AnonCVS</a>.
1006: So, in order to keep up to date with the -stable branch, you must make
1007: the <i>ports/</i> tree available on a read-write medium and update the tree
1008: with a command like:
1009: <blockquote><pre>
1010: # <kbd>cd /usr/ports</kbd>
1011: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_5</kbd>
1012: </pre></blockquote>
1013: <p>
1014: [Of course, you must replace the server name here with a nearby anoncvs
1015: server.]
1016: <p>
1017: Note that most ports are available as packages on our mirrors. Updated
1018: ports for the 7.5 release will be made available if problems arise.
1019: <p>
1020: If you're interested in seeing a port added, would like to help out, or just
1021: would like to know more, the mailing list
1022: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
