145 Release Notes for Samba 4.17.4
147 ==============================
150 This is the latest stable release of the Samba 4.17 release series.
151 It also contains security changes in order to address the following defects:
154 o CVE-2022-37966: This is the Samba CVE for the Windows Kerberos
155 RC4-HMAC Elevation of Privilege Vulnerability
156 disclosed by Microsoft on Nov 8 2022.
158 A Samba Active Directory DC will issue weak rc4-hmac
159 session keys for use between modern clients and servers
160 despite all modern Kerberos implementations supporting
161 the aes256-cts-hmac-sha1-96 cipher.
163 On Samba Active Directory DCs and members
164 'kerberos encryption types = legacy' would force
165 rc4-hmac as a client even if the server supports
166 aes128-cts-hmac-sha1-96 and/or aes256-cts-hmac-sha1-96.
168 https://www.samba.org/samba/security/CVE-2022-37966.html
170 o CVE-2022-37967: This is the Samba CVE for the Windows
171 Kerberos Elevation of Privilege Vulnerability
172 disclosed by Microsoft on Nov 8 2022.
174 A service account with the special constrained
175 delegation permission could forge a more powerful
176 ticket than the one it was presented with.
178 https://www.samba.org/samba/security/CVE-2022-37967.html
180 o CVE-2022-38023: The "RC4" protection of the NetLogon Secure channel uses the
181 same algorithms as rc4-hmac cryptography in Kerberos,
182 and so must also be assumed to be weak.
184 https://www.samba.org/samba/security/CVE-2022-38023.html
186 Note that there are several important behavior changes
187 included in this release, which may cause compatibility problems
188 interacting with system still expecting the former behavior.
189 Please read the advisories of CVE-2022-37966,
190 CVE-2022-37967 and CVE-2022-38023 carefully!
192 samba-tool got a new 'domain trust modify' subcommand
193 -----------------------------------------------------
195 This allows "msDS-SupportedEncryptionTypes" to be changed
196 on trustedDomain objects. Even against remote DCs (including Windows)
197 using the --local-dc-ipaddress= (and other --local-dc-* options).

481 Release Notes for Samba 4.17.0
483 ==============================
486 This is the first stable release of the Samba 4.17 release series.
487 Please read the release notes carefully before upgrading.
493 SMB Server performance improvements
494 -----------------------------------
496 The security improvements in recent releases
497 (4.13, 4.14, 4.15, 4.16), mainly as protection against symlink races,
498 caused performance regressions for meta data heavy workloads.
500 With 4.17 the situation improved a lot again:
502 - Pathnames given by a client are devided into dirname and basename.
503 The amount of syscalls to validate dirnames is reduced to 2 syscalls
504 (openat, close) per component. On modern Linux kernels (>= 5.6) smbd
505 makes use of the openat2() syscall with RESOLVE_NO_SYMLINKS,
506 in order to just use 2 syscalls (openat2, close) for the whole dirname.
508 - Contended path based operations used to generate a lot of unsolicited
509 wakeup events causing thundering herd problems, which lead to masive
510 latencies for some clients. These events are now avoided in order
511 to provide stable latencies and much higher throughput of open/close
514 Configure without the SMB1 Server
515 ---------------------------------
517 It is now possible to configure Samba without support for
518 the SMB1 protocol in smbd. This can be selected at configure
519 time with either of the options:
522 --without-smb1-server
524 By default (without either of these options set) Samba
525 is configured to include SMB1 support (i.e. --with-smb1-server
526 is the default). When Samba is configured without SMB1 support,
527 none of the SMB1 code is included inside smbd except the minimal
528 stub code needed to allow a client to connect as SMB1 and immediately
529 negotiate the selected protocol into SMB2 (as a Windows server also
532 None of the SMB1-only smb.conf parameters are removed when
533 configured without SMB1, but these parameters are ignored by
534 the smbd server. This allows deployment without having to change
535 an existing smb.conf file.
537 This option allows sites, OEMs and integrators to configure Samba
538 to remove the old and insecure SMB1 protocol from their products.
540 Note that the Samba client libraries still support SMB1 connections
541 even when Samba is configured as --without-smb1-server. This is
542 to ensure maximum compatibility with environments containing old
545 Bronze bit and S4U support now also with MIT Kerberos 1.20
546 ----------------------------------------------------------
548 In 2020 Microsoft Security Response Team received another Kerberos-related
549 report. Eventually, that led to a security update of the CVE-2020-17049,
550 Kerberos KDC Security Feature Bypass Vulnerability, also known as a ‘Bronze
551 Bit’. With this vulnerability, a compromised service that is configured to use
552 Kerberos constrained delegation feature could tamper with a service ticket that
553 is not valid for delegation to force the KDC to accept it.
555 With the release of MIT Kerberos 1.20, Samba AD DC is able able to mitigate the
556 ‘Bronze Bit’ attack. MIT Kerberos KDC's KDB (Kerberos Database Driver) API was
557 changed to allow passing more details between KDC and KDB components. When built
558 against MIT Kerberos, Samba AD DC supports MIT Kerberos 1.19 and 1.20 versions
559 but 'Bronze Bit' mitigation is provided only with MIT Kerberos 1.20.
561 In addition to fixing the ‘Bronze Bit’ issue, Samba AD DC now fully supports
562 S4U2Self and S4U2Proxy Kerberos extensions.
564 Note the default (Heimdal-based) KDC was already fixed in 2021,
565 see https://bugzilla.samba.org/show_bug.cgi?id=14642
567 Resource Based Constrained Delegation (RBCD) support
568 ----------------------------------------------------
570 Samba AD DC built with MIT Kerberos 1.20 offers RBCD support now. With MIT
571 Kerberos 1.20 we have complete RBCD support passing Sambas S4U testsuite.
573 samba-tool delegation got the 'add-principal' and 'del-principal' subcommands
574 in order to manage RBCD.
576 To complete RBCD support and make it useful to Administrators we added the
577 Asserted Identity [1] SID into the PAC for constrained delegation. This is
578 available for Samba AD compiled with MIT Kerberos 1.20.
580 Note the default (Heimdal-based) KDC does not support RBCD yet.
582 [1] https://docs.microsoft.com/en-us/windows-server/security/kerberos/kerberos-constrained-delegation-overview
584 Customizable DNS listening port
585 -------------------------------
587 It is now possible to set a custom listening port for the builtin DNS service,
588 making easy to host another DNS on the same system that would bind to the
589 default port and forward the domain-specific queries to Samba using the custom
590 port. This is the opposite configuration of setting a forwarder in Samba.
592 It makes possible to use another DNS server as a front and forward to Samba.
594 Dynamic DNS updates may not be proxied by the front DNS server when forwarding
595 to Samba. Dynamic DNS update proxying depends on the features of the other DNS
596 server used as a front.
601 * When Samba is configured with both --with-cluster-support and
602 --systemd-install-services then a systemd service file for CTDB will
605 * ctdbd_wrapper has been removed. ctdbd is now started directly from
606 a systemd service file or init script.
608 * The syntax for the ctdb.tunables configuration file has been
609 relaxed. However, trailing garbage after the value, including
610 comments, is no longer permitted. Please see ctdb-tunables(7) for
613 Operation without the (unsalted) NT password hash
614 -------------------------------------------------
616 When Samba is configured with 'nt hash store = never' then Samba will
617 no longer store the (unsalted) NT password hash for users in Active
618 Directory. (Trust accounts, like computers, domain controllers and
619 inter-domain trusts are not impacted).
621 In the next version of Samba the default for 'nt hash store' will
622 change from 'always' to 'auto', where it will follow (behave as 'nt
623 hash store = never' when 'ntlm auth = disabled' is set.
625 Security-focused deployments of Samba that have eliminated NTLM from
626 their networks will find setting 'ntlm auth = disabled' with 'nt hash
627 store = always' as a useful way to improve compliance with
628 best-practice guidance on password storage (which is to always use an
631 Note that when 'nt hash store = never' is set, then arcfour-hmac-md5
632 Kerberos keys will not be available for users who subsequently change
633 their password, as these keys derive their values from NT hashes. AES
634 keys are stored by default for all deployments of Samba with Domain
635 Functional Level 2008 or later, are supported by all modern clients,
636 and are much more secure.
638 Finally, also note that password history in Active Directory is stored
639 in nTPwdHistory using a series of NT hash values. Therefore the full
640 password history feature is not available in this mode.
642 To provide some protection against password re-use previous Kerberos
643 hash values (the current, old and older values are already stored) are
644 used, providing a history length of 3.
646 There is one small limitation of this workaround: Changing the
647 sAMAccountName, userAccountControl or userPrincipalName of an account
648 can cause the Kerberos password salt to change. This means that after
649 *both* an account rename and a password change, only the current
650 password will be recognised for password history purposes.
652 Python API for smbconf
653 ----------------------
655 Samba's smbconf library provides a generic frontend to various
656 configuration backends (plain text file, registry) as a C library. A
657 new Python wrapper, importable as 'samba.smbconf' is available. An
658 additional module, 'samba.samba3.smbconf', is also available to enable
659 registry backend support. These libraries allow Python programs to
660 read, and optionally write, Samba configuration natively.
662 JSON support for smbstatus
663 --------------------------
665 It is now possible to print detailed information in JSON format in
666 the smbstatus program using the new option --json. The JSON output
667 covers all the existing text output including sessions, connections,
668 open files, byte-range locks, notifies and profile data with all
669 low-level information maintained by Samba in the respective databases.
671 Protected Users security group
672 ------------------------------
674 Samba AD DC now includes support for the Protected Users security
675 group introduced in Windows Server 2012 R2. The feature reduces the
676 attack surface of user accounts by preventing the use of weak
677 encryption types. It also mitigates the effects of credential theft by
678 limiting credential lifetime and scope.
680 The protections are intended for user accounts only, and service or
681 computer accounts should not be added to the Protected Users
682 group. User accounts added to the group are granted the following
683 security protections:
685 * NTLM authentication is disabled.
686 * Kerberos ticket-granting tickets (TGTs) encrypted with RC4 are
687 not issued to or accepted from affected principals. Tickets
688 encrypted with AES, and service tickets encrypted with RC4, are
689 not affected by this restriction.
690 * The lifetime of Kerberos TGTs is restricted to a maximum of four
692 * Kerberos constrained and unconstrained delegation is disabled.
694 If the Protected Users group is not already present in the domain, it
695 can be created with 'samba-tool group add'. The new '--special'
696 parameter must be specified, with 'Protected Users' as the name of the
697 group. An example command invocation is:
699 samba-tool group add 'Protected Users' --special
701 or against a remote server:
703 samba-tool group add 'Protected Users' --special -H ldap://dc1.example.com -U Administrator
705 The Protected Users group is identified in the domain by its having a
706 RID of 525. Thus, it should only be created with samba-tool and the
707 '--special' parameter, as above, so that it has the required RID
708 to function correctly.
714 LanMan Authentication and password storage removed from the AD DC
715 -----------------------------------------------------------------
717 The storage and authentication with LanMan passwords has been entirely
718 removed from the Samba AD DC, even when "lanman auth = yes" is set.
724 Parameter Name Description Default
725 -------------- ----------- -------
726 dns port New default 53
727 fruit:zero_file_id New default yes
728 nt hash store New parameter always
729 smb1 unix extensions Replaces "unix extensions"
730 volume serial number New parameter -1
731 winbind debug traceid New parameter no
