                   =============================
                   Release Notes for Samba 4.2.7
                         December 16, 2015
                   =============================


This is a security release in order to address the following CVEs:

o  CVE-2015-3223 (Denial of service in Samba Active Directory
		  server)
o  CVE-2015-5252 (Insufficient symlink verification in smbd)
o  CVE-2015-5299 (Missing access control check in shadow copy
		  code)
o  CVE-2015-5296 (Samba client requesting encryption vulnerable
		  to downgrade attack)
o  CVE-2015-8467 (Denial of service attack against Windows
		  Active Directory server)
o  CVE-2015-5330 (Remote memory read in Samba LDAP server)

Please note that if building against a system libldb, the required
version has been bumped to ldb-1.1.24.  This is needed to ensure
we build against a system ldb library that contains the fixes
for CVE-2015-5330 and CVE-2015-3223.

=======
Details
=======

o  CVE-2015-3223:
   All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
   ldb versions up to 1.1.23 inclusive) are vulnerable to
   a denial of service attack in the samba daemon LDAP server.

   A malicious client can send packets that cause the LDAP server in the
   samba daemon process to become unresponsive, preventing the server
   from servicing any other requests.

   This flaw is not exploitable beyond causing the code to loop expending
   CPU resources.

o  CVE-2015-5252:
   All versions of Samba from 3.0.0 to 4.3.2 inclusive are vulnerable to
   a bug in symlink verification, which under certain circumstances could
   allow client access to files outside the exported share path.

   If a Samba share is configured with a path that shares a common path
   prefix with another directory on the file system, the smbd daemon may
   allow the client to follow a symlink pointing to a file or directory
   in that other directory, even if the share parameter "wide links" is
   set to "no" (the default).

o  CVE-2015-5299:
   All versions of Samba from 3.2.0 to 4.3.2 inclusive are vulnerable to
   a missing access control check in the vfs_shadow_copy2 module. When
   looking for the shadow copy directory under the share path the current
   accessing user should have DIRECTORY_LIST access rights in order to
   view the current snapshots.

   This was not being checked in the affected versions of Samba.

o  CVE-2015-5296:
   Versions of Samba from 3.2.0 to 4.3.2 inclusive do not ensure that
   signing is negotiated when creating an encrypted client connection to
   a server.

   Without this a man-in-the-middle attack could downgrade the connection
   and connect using the supplied credentials as an unsigned, unencrypted
   connection.

o  CVE-2015-8467:
   Samba, operating as an AD DC, is sometimes operated in a domain with a
   mix of Samba and Windows Active Directory Domain Controllers.

   All versions of Samba from 4.0.0 to 4.3.2 inclusive, when deployed as
   an AD DC in the same domain with Windows DCs, could be used to
   override the protection against the MS15-096 / CVE-2015-2535 security
   issue in Windows.

   Prior to MS16-096 it was possible to bypass the quota of machine
   accounts a non-administrative user could create.  Pure Samba domains
   are not impacted, as Samba does not implement the
   SeMachineAccountPrivilege functionality to allow non-administrator
   users to create new computer objects.

o  CVE-2015-5330:
   All versions of Samba from 4.0.0 to 4.3.2 inclusive (resp. all
   ldb versions up to 1.1.23 inclusive) are vulnerable to
   a remote memory read attack in the samba daemon LDAP server.

   A malicious client can send packets that cause the LDAP server in the
   samba daemon process to return heap memory beyond the length of the
   requested value.

   This memory may contain data that the client should not be allowed to
   see, allowing compromise of the server.

   The memory may either be returned to the client in an error string, or
   stored in the database by a suitabily privileged user.  If untrusted
   users can create objects in your database, please confirm that all DN
   and name attributes are reasonable.


Changes since 4.2.6:
--------------------

o  Andrew Bartlett <abartlet@samba.org>
   * BUG 11552: CVE-2015-8467: samdb: Match MS15-096 behaviour for
     userAccountControl.

o  Jeremy Allison <jra@samba.org>
   * BUG 11325: CVE-2015-3223: Fix LDAP \00 search expression attack DoS.
   * BUG 11395: CVE-2015-5252: Fix insufficient symlink verification (file
     access outside the share).
   * BUG 11529: CVE-2015-5299: s3-shadow-copy2: Fix missing access check on
     snapdir.

o  Douglas Bagnall <douglas.bagnall@catalyst.net.nz>
   * BUG 11599: CVE-2015-5330: Fix remote read memory exploit in LDB.

o  Stefan Metzmacher <metze@samba.org>
   * BUG 11536: CVE-2015-5296: Add man in the middle protection when forcing
     smb encryption on the client side.

                   =============================
                   Release Notes for Samba 4.2.0
                           March 04, 2015
                   =============================


This is is the first stable release of Samba 4.2.

Samba 4.2 will be the next version of the Samba suite.


Samba User Survey 2015
======================

https://www.surveygizmo.com/s3/2020369/Samba-User-Survey-2015

Please take our survey. It will help us improve Samba by understanding
your knowledge and needs. The survey runs until end of March 2015 and
won't ask for any personal info. The full results will be shared with
the Samba Team, and statistical summaries will be shared with the
Samba community after the SambaXP conference (http://sambaxp.org).


IMPORTANT NOTE ABOUT THE SUPPORT END OF SAMBA 3
=================================================

With the final release of Samba 4.2, the last series of Samba 3 has
been discontinued! People still running 3.6.x or earlier,should
consider moving to a more recent and maintained version (4.0 - 4.2).
One of the common misconceptions is that Samba 4.x automatically
means "Active Directory only": This is wrong!

Acting as an Active Directory Domain Controller is just one of the
enhancements included in Samba 4.0 and later. Version 4.0 was just the
next release after the 3.6 series and contains all the features of the
previous ones - including the NT4-style (classic) domain support. This
means you can update a Samba 3.x NT4-style PDC to 4.x, just as you've
updated in the past (e.g. from 3.4.x to 3.5.x). You don't have to move
your NT4-style domain to an Active Directory!

And of course the possibility remains unchanged, to setup a new NT4-style
PDC with Samba 4.x, like done in the past (e.g. with openLDAP backend).
Active Directory support in Samba 4 is additional and does not replace
any of these features. We do understand the difficulty presented by
existing LDAP structures and for that reason there isn't a plan to
decommission the classic PDC support. It remains tested by the continuous
integration system.

The code that supports the classic Domain Controller is also the same
code that supports the internal 'Domain' of standalone servers and
Domain Member Servers. This means that we still use this code, even
when not acting as an AD Domain Controller. It is also the basis for
some of the features of FreeIPA and so it gets development attention
from that direction as well.


UPGRADING
=========

Read the "Winbindd/Netlogon improvements" section (below) carefully!


NEW FEATURES
============

Transparent File Compression
============================

Samba 4.2.0 adds support for the manipulation of file and folder
compression flags on the Btrfs filesystem.
With the Btrfs Samba VFS module enabled, SMB2+ compression flags can
be set remotely from the Windows Explorer File->Properties->Advanced
dialog. Files flagged for compression are transparently compressed
and uncompressed when accessed or modified.

Previous File Versions with Snapper
===================================

The newly added Snapper VFS module exposes snapshots managed by
Snapper for use by Samba. This provides the ability for remote
clients to access shadow-copies via Windows Explorer using the
"previous versions" dialog.

Winbindd/Netlogon improvements
==============================

The whole concept of maintaining the netlogon secure channel
to (other) domain controllers was rewritten in order to maintain
global state in a netlogon_creds_cli.tdb. This is the proper fix
for a large number of bugs:

  https://bugzilla.samba.org/show_bug.cgi?id=6563
  https://bugzilla.samba.org/show_bug.cgi?id=7944
  https://bugzilla.samba.org/show_bug.cgi?id=7945
  https://bugzilla.samba.org/show_bug.cgi?id=7568
  https://bugzilla.samba.org/show_bug.cgi?id=8599

In addition a strong session key is now required by default,
which means that communication to older servers or clients
might be rejected by default.

For the client side we have the following new options:
"require strong key" (yes by default), "reject md5 servers" (no by default).
E.g. for Samba 3.0.37 you need "require strong key = no" and
for NT4 DCs you need "require strong key = no" and "client NTLMv2 auth = no",

On the server side (as domain controller) we have the following new options:
"allow nt4 crypto" (no by default), "reject md5 client" (no by default).
E.g. in order to allow Samba < 3.0.27 or NT4 members to work
you need "allow nt4 crypto = yes"

winbindd does not list group memberships for display purposes
(e.g. getent group <domain\<group>) anymore by default.
The new default is "winbind expand groups = 0" now,
the reason for this is the same as for "winbind enum users = no"
and "winbind enum groups = no". Providing this information is not always
reliably possible, e.g. if there are trusted domains.

Please consult the smb.conf manpage for more details on these new options.

Winbindd use on the Samba AD DC
===============================

Winbindd is now used on the Samba AD DC by default, replacing the
partial rewrite used for winbind operations in Samba 4.0 and 4.1.

This allows more code to be shared, more options to be honoured, and
paves the way for support for trusted domains in the AD DC.

If required the old internal winbind can be activated by setting
'server services = +winbind -winbindd'.  Upgrading users with a server
services parameter specified should ensure they change 'winbind' to
'winbindd' to obtain the new functionality.

The 'samba' binary still manages the starting of this service, there
is no need to start the winbindd binary manually.

Winbind now requires secured connections
========================================

To improve protection against rogue domain controllers we now require
that when we connect to an AD DC in our forest, that the connection be
signed using SMB Signing.  Set 'client signing = off' in the smb.conf
to disable.

Also and DCE/RPC pipes must be sealed, set 'require strong key =
false' and 'winbind sealed pipes = false' to disable.

Finally, the default for 'client ldap sasl wrapping' has been set to
'sign', to ensure the integrity of LDAP connections.  Set 'client ldap
sasl wrapping = plain' to disable.

Larger IO sizes for SMB2/3 by default
=====================================

The default values for "smb2 max read", "smb2 max write" and "smb2 max trans"
have been changed to 8388608 (8MiB) in order to match the default of
Windows 2012R2.

SMB2 leases
===========

The SMB2 protocol allows clients to aggressively cache files
locally above and beyond the caching allowed by SMB1 and SMB2 oplocks.

Called SMB2 leases, this can greatly reduce traffic on an SMB2
connection. Samba 4.2 now implements SMB2 leases.

It can be turned on by setting the parameter "smb2 leases = yes"
in the [global] section of your smb.conf. This parameter is set
to off by default until the SMB2 leasing code is declared fully stable.

Improved DCERPC man in the middle detection
===========================================

The DCERPC header signing has been implemented
in addition to the dcerpc_sec_verification_trailer
protection.

Overhauled "net idmap" command
==============================

The command line interface of the "net idmap" command has been
made systematic, and subcommands for reading and writing the autorid idmap
database have been added. Note that the writing commands should be
used with great care. See the net(8) manual page for details.

tdb improvements
================

The tdb library, our core mechanism to store Samba-specific data on disk and
share it between processes, has been improved to support process shared robust
mutexes on Linux. These mutexes are available on Linux and Solaris and
significantly reduce the overhead involved with tdb. To enable mutexes for
tdb, set

dbwrap_tdb_mutexes:* = yes

in the [global] section of your smb.conf.

Tdb file space management has also been made more efficient. This
will lead to smaller and less fragmented databases.

Messaging improvements
======================

Our internal messaging subsystem, used for example for things like oplock
break messages between smbds or setting a process debug level dynamically, has
been rewritten to use unix domain datagram messages.

Clustering support
==================

Samba's file server clustering component CTDB is now integrated in the
Samba tree.  This avoids the confusion of compatibility of Samba and CTDB
versions as existed previously.

To build the Samba file server with cluster support, use the configure
command line option --with-cluster-support.  This will build clustered
file server against the in-tree CTDB and will also build CTDB.
Building clustered samba with previous versions of CTDB is no longer
supported.

Samba Registry Editor
=====================

The utitlity to browse the samba registry has been overhauled by our Google
Summer of Code student Chris Davis. Now samba-regedit has a
Midnight-Commander-like theme and UI experience. You can browse keys and edit
the diffent value types. For a data value type a hexeditor has been
implemented.

Bad Password Lockout in the AD DC
=================================

Samba's AD DC now implements bad password lockout (on a per-DC basis).

That is, incorrect password attempts are tracked, and accounts locked
out if too many bad passwords are submitted.  There is also a grace
period of 60 minutes on the previous password when used for NTLM
authentication (matching Windows 2003 SP1: https://support2.microsoft.com/kb/906305).

The relevant settings can be seen using 'samba-tool domain
passwordsettings show' (the new settings being highlighted):

Password informations for domain 'DC=samba,DC=example,DC=com'

Password complexity: on
Store plaintext passwords: off
Password history length: 24
Minimum password length: 7
Minimum password age (days): 1
Maximum password age (days): 42
* Account lockout duration (mins): 30     *
* Account lockout threshold (attempts): 0 *
* Reset account lockout after (mins): 30  *

These values can be set using 'samba-tool domain passwordsettings set'.

Correct defaults in the smb.conf manpages
=========================================

The default values for smb.conf parameters are now correctly specified
in the smb.conf manpage, even when they refer to build-time specified
paths.  Provided Samba is built on a system with the right tools
(xsltproc in particular) required to generate our man pages, then
these will be built with the exact same embedded paths as used by the
configuration parser at runtime.  Additionally, the default values
read from the smb.conf manpage are checked by our test suite to match
the values seen in testparm and used by the running binaries.

Consistent behaviour between samba-tool testparm and testparm
=============================================================

With the exception of the registry backend, which remains only
available in the file server, the behaviour of the smb.conf parser and
the tools 'samba-tool testparm' and 'testparm' is now consistent,
particularly with regard to default values.  Except with regard to
registry shares, it is no longer needed to use one tool on the AD
DC, and another on the file server.

VFS WORM module
===============

A VFS module for basic WORM (Write once read many) support has been
added. It allows an additional layer on top of a Samba share, that provides
a basic set of WORM functionality on the client side, to control the
writeability of files and folders.

As the module is simply an additional layer, share access and permissions
work like expected - only WORM functionality is added on top. Removing the
module from the share configuration, removes this layer again. The
filesystem ACLs are not affected in any way from the module and treated
as usual.

The module does not provide complete WORM functions, like some archiving
products do! It is not audit-proof, because the WORM function is only
available on the client side, when accessing a share through SMB! If
the same folder is shared by other services like NFS, the access only
depends on the underlying filesystem ACLs. Equally if you access the
content directly on the server.

For additional information, see
https://wiki.samba.org/index.php/VFS/vfs_worm

vfs_fruit, a VFS module for OS X clients
========================================

A new VFS module that provides enhanced compatibility with Apple SMB
clients and interoperability with a Netatalk 3 AFP fileserver.

The module features enhanced performance with reliable named streams
support, interoperability with special characters commonly used by OS
X client (eg '*', '/'), integrated file locking and Mac metadata
access with Netatalk 3 and enhanced performance by implementing
Apple's SMB2 extension codenamed "AAPL".

The modules behaviour is fully configurable, please refer to the
manpage vfs_fruit for further details.

smbclient archival improvements
===============================

Archive creation and extraction support in smbclient has been rewritten
to use libarchive. This fixes a number of outstanding bugs in Samba's
previous custom tar implementation and also adds support for the
extraction of zipped archives.
smbclient archive support can be enabled or disabled at build time with
corresponding --with[out]-libarchive configure parameters.
