2 Release Notes for Samba 4.3.6
4 =============================
7 This is a security release in order to address the following CVEs:
9 o CVE-2015-7560 (Incorrect ACL get/set allowed on symlink path)
10 o CVE-2016-0771 (Out-of-bounds read in internal DNS server)
17 All versions of Samba from 3.2.0 to 4.4.0rc3 inclusive are vulnerable to
18 a malicious client overwriting the ownership of ACLs using symlinks.
20 An authenticated malicious client can use SMB1 UNIX extensions to
21 create a symlink to a file or directory, and then use non-UNIX SMB1
22 calls to overwrite the contents of the ACL on the file or directory
26 All versions of Samba from 4.0.0 to 4.4.0rc3 inclusive, when deployed as
27 an AD DC and choose to run the internal DNS server, are vulnerable to an
28 out-of-bounds read issue during DNS TXT record handling caused by users
29 with permission to modify DNS records.
31 A malicious client can upload a specially constructed DNS TXT record,
32 resulting in a remote denial-of-service attack. As long as the affected
33 TXT record remains undisturbed in the Samba database, a targeted DNS
34 query may continue to trigger this exploit.
36 While unlikely, the out-of-bounds read may bypass safety checks and
37 allow leakage of memory from the server in the form of a DNS TXT reply.
39 By default only authenticated accounts can upload DNS records,
40 as "allow dns updates = secure only" is the default.
41 Any other value would allow anonymous clients to trigger this
42 bug, which is a much higher risk.

50 change permissions on link target.

245 Release Notes for Samba 4.3.3
247 =============================
250 This is a security release in order to address the following CVEs:
252 o CVE-2015-3223 (Denial of service in Samba Active Directory
254 o CVE-2015-5252 (Insufficient symlink verification in smbd)
255 o CVE-2015-5299 (Missing access control check in shadow copy
257 o CVE-2015-5296 (Samba client requesting encryption vulnerable
259 o CVE-2015-8467 (Denial of service attack against Windows
260 Active Directory server)
261 o CVE-2015-5330 (Remote memory read in Samba LDAP server)
263 Please note that if building against a system libldb, the required
264 version has been bumped to ldb-1.1.24. This is needed to ensure
265 we build against a system ldb library that contains the fixes
266 for CVE-2015-5330 and CVE-2015-3223.
273 All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
274 ldb versions up to 1.1.23 inclusive) are vulnerable to
275 a denial of service attack in the samba daemon LDAP server.
277 A malicious client can send packets that cause the LDAP server in the
278 samba daemon process to become unresponsive, preventing the server
279 from servicing any other requests.
281 This flaw is not exploitable beyond causing the code to loop expending
285 All versions of Samba from 3.0.0 to 4.3.2 inclusive are vulnerable to
286 a bug in symlink verification, which under certain circumstances could
287 allow client access to files outside the exported share path.
289 If a Samba share is configured with a path that shares a common path
290 prefix with another directory on the file system, the smbd daemon may
291 allow the client to follow a symlink pointing to a file or directory
292 in that other directory, even if the share parameter "wide links" is
293 set to "no" (the default).
296 All versions of Samba from 3.2.0 to 4.3.2 inclusive are vulnerable to
297 a missing access control check in the vfs_shadow_copy2 module. When
298 looking for the shadow copy directory under the share path the current
299 accessing user should have DIRECTORY_LIST access rights in order to
300 view the current snapshots.
302 This was not being checked in the affected versions of Samba.
305 Versions of Samba from 3.2.0 to 4.3.2 inclusive do not ensure that
306 signing is negotiated when creating an encrypted client connection to
309 Without this a man-in-the-middle attack could downgrade the connection
310 and connect using the supplied credentials as an unsigned, unencrypted
314 Samba, operating as an AD DC, is sometimes operated in a domain with a
315 mix of Samba and Windows Active Directory Domain Controllers.
317 All versions of Samba from 4.0.0 to 4.3.2 inclusive, when deployed as
318 an AD DC in the same domain with Windows DCs, could be used to
319 override the protection against the MS15-096 / CVE-2015-2535 security
322 Prior to MS16-096 it was possible to bypass the quota of machine
323 accounts a non-administrative user could create. Pure Samba domains
324 are not impacted, as Samba does not implement the
325 SeMachineAccountPrivilege functionality to allow non-administrator
326 users to create new computer objects.
329 All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
330 ldb versions up to 1.1.23 inclusive) are vulnerable to
331 a remote memory read attack in the samba daemon LDAP server.
333 A malicious client can send packets that cause the LDAP server in the
334 samba daemon process to return heap memory beyond the length of the
337 This memory may contain data that the client should not be allowed to
338 see, allowing compromise of the server.
340 The memory may either be returned to the client in an error string, or
341 stored in the database by a suitabily privileged user. If untrusted
342 users can create objects in your database, please confirm that all DN
343 and name attributes are reasonable.

553 ======================================================================
556 ----------------------------------------------------------------------
559 =============================
560 Release Notes for Samba 4.3.0
562 =============================
565 This is the first stable release of Samba 4.3.
571 Read the "New FileChangeNotify subsystem" and "smb.conf changes" sections
581 The logging code now supports logging to multiple backends. In
582 addition to the previously available syslog and file backends, the
583 backends for logging to the systemd-journal, lttng and gpfs have been
584 added. Please consult the section for the 'logging' parameter in the
585 smb.conf manpage for details.
590 Support for Apple's Spotlight has been added by integrating with Gnome
593 For detailed instructions how to build and setup Samba for Spotlight,
594 please see the Samba wiki: <https://wiki.samba.org/index.php/Spotlight>
596 New FileChangeNotify subsystem
597 ------------------------------
599 Samba now contains a new subsystem to do FileChangeNotify. The
600 previous system used a central database, notify_index.tdb, to store
601 all notification requests. In particular in a cluster this turned out
602 to be a major bottleneck, because some hot records need to be bounced
603 back and forth between nodes on every change event like a new created
606 The new FileChangeNotify subsystem works with a central daemon per
607 node. Every FileChangeNotify request and every event are handled by an
608 asynchronous message from smbd to the notify daemon. The notify daemon
609 maintains a database of all FileChangeNotify requests in memory and
610 will distribute the notify events accordingly. This database is
611 asynchronously distributed in the cluster by the notify daemons.
613 The notify daemon is supposed to scale a lot better than the previous
614 implementation. The functional advantage is cross-node kernel change
615 notify: Files created via NFS will be seen by SMB clients on other
616 nodes per FileChangeNotify, despite the fact that popular cluster file
617 systems do not offer cross-node inotify.
619 Two changes to the configuration were required for this new subsystem:
620 The parameters "change notify" and "kernel change notify" are not
621 per-share anymore but must be set globally. So it is no longer
622 possible to enable or disable notify per share, the notify daemon has
623 no notion of a share, it only works on absolute paths.
625 New SMB profiling code
626 ----------------------
628 The code for SMB (SMB1, SMB2 and SMB3) profiling uses a tdb instead
629 of sysv IPC shared memory. This avoids performance problems and NUMA
630 effects. The profile stats are a bit more detailed than before.
632 Improved DCERPC man in the middle detection for kerberos
633 --------------------------------------------------------
635 The gssapi based kerberos backends for gensec have support for
636 DCERPC header signing when using DCERPC_AUTH_LEVEL_PRIVACY.
638 SMB signing required in winbindd by default
639 -------------------------------------------
641 The effective value for "client signing" is required
642 by default for winbindd, if the primary domain uses active directory.
644 Experimental NTDB was removed
645 -----------------------------
647 The experimental NTDB library introduced in Samba 4.0 has been
650 Improved support for trusted domains (as AD DC)
651 -----------------------------------------------
653 The support for trusted domains/forests has improved a lot.
655 samba-tool got "domain trust" subcommands to manage trusts:
657 create - Create a domain or forest trust.
658 delete - Delete a domain trust.
659 list - List domain trusts.
660 namespaces - Manage forest trust namespaces.
661 show - Show trusted domain details.
662 validate - Validate a domain trust.
664 External trusts between individual domains work in both ways
665 (inbound and outbound). The same applies to root domains of
666 a forest trust. The transitive routing into the other forest
667 is fully functional for kerberos, but not yet supported for NTLMSSP.
669 While a lot of things are working fine, there are currently a few limitations:
671 - Both sides of the trust need to fully trust each other!
672 - No SID filtering rules are applied at all!
673 - This means DCs of domain A can grant domain admin rights
675 - It's not possible to add users/groups of a trusted domain
681 Both client and server have support for SMB 3.1.1 now.
683 This is the dialect introduced with Windows 10, it improves the secure
684 negotiation of SMB dialects and features.
686 There's also a new optinal encryption algorithm aes-gcm-128,
687 but for now this is only selected as fallback and aes-ccm-128
688 is preferred because of the better performance. This might change
689 in future versions when hardware encryption will be supported.

720 vfs_shell_snap - see 'man 8 vfs_shell_snap'
722 New sparsely connected replia graph (Improved KCC)
723 --------------------------------------------------
725 The Knowledge Consistency Checker (KCC) maintains a replication graph
726 for DCs across an AD network. The existing Samba KCC uses a fully
727 connected graph, so that each DC replicates from all the others, which
728 does not scale well with large networks. In 4.3 there is an
729 experimental new KCC that creates a sparsely connected replication
730 graph and closely follows Microsoft's specification. It is turned off
731 by default. To use the new KCC, set "kccsrv:samba_kcc=true" in
732 smb.conf and let us know how it goes. You should consider doing this
733 if you are making a large new network. For small networks there is
734 little benefit and you can always switch over at a later date.
736 Configurable TLS protocol support, with better defaults
737 -------------------------------------------------------
739 The "tls priority" option can be used to change the supported TLS
740 protocols. The default is to disable SSLv3, which is no longer
743 Samba-tool now supports all 7 FSMO roles
744 -------------------------------------------------------
746 Previously "samba-tool fsmo" could only show, transfer or seize the
747 five well-known FSMO roles:
753 Infrastructure Master
755 It can now also show, transfer or seize the DNS infrastructure roles:
757 DomainDnsZones Infrastructure Master
758 ForestDnsZones Infrastructure Master
763 The destination for CTDB logging is now set via a single new
764 configuration variable CTDB_LOGGING. This replaces CTDB_LOGFILE and
765 CTDB_SYSLOG, which have both been removed. See ctdbd.conf(5) for
766 details of CTDB_LOGGING.
768 CTDB no longer runs a separate logging daemon.
770 CTDB NFS support changes
771 ------------------------
773 CTDB's NFS service management has been combined into a single 60.nfs
774 event script. This updated 60.nfs script now uses a call-out to
775 interact with different NFS implementations. See the CTDB_NFS_CALLOUT
776 option in the ctdbd.conf(5) manual page for details. A default
777 call-out is provided to interact with the Linux kernel NFS
778 implementation. The 60.ganesha event script has been removed - a
779 sample call-out is provided for NFS Ganesha, based on this script.
781 The method of configuring NFS RPC checks has been improved. See
782 ctdb/config/nfs-checks.d/README for details.
784 Improved Cross-Compiling Support
785 --------------------------------
787 A new "hybrid" build configuration mode is added to improve
788 cross-compilation support.
790 A common challenge in cross-compilation is that of obtaining the results
791 of tests that have to run on the target, during the configuration
792 phase of the build. The Samba build system already supports the following
795 - Executing configure tests using the --cross-execute parameter
796 - Obtaining the results from an answers file using the --cross-answers
799 The first method has the drawback of inaccurate results if the tests are
800 run using an emulator, or a need to be connected to a running target
801 while building, if the tests are to be run on an actual target. The
802 second method presents a challenge of figuring out the test results.
804 The new hybrid mode runs the tests and records the result in an answer file.
805 To activate this mode, use both --cross-execute and --cross-answers in the
806 same configure invocation. This mode can be activated once against a
807 running target, and then the generated answers file can be used in
810 Also supplied is an example script that can be used as the
811 cross-execute program. This script copies the test to a running target
812 and runs the test on the target, obtaining the result. The obtained
813 results are more accurate than running the test with an emulator, because
814 they reflect the exact kernel and system libraries that exist on the
817 Improved Sparse File Support
818 ----------------------------
819 Support for the FSCTL_SET_ZERO_DATA and FSCTL_QUERY_ALLOCATED_RANGES
820 SMB2 requests has been added to the smbd file server.
821 This allows for clients to deallocate (hole punch) regions within a
822 sparse file, and check which portions of a file are allocated.
