                   Release Notes for Samba 4.0.25
                          February 23, 2015
                   ==============================


This is a security release in order to address CVE-2015-0240 (Unexpected
code execution in smbd).

o  CVE-2015-0240:
   All versions of Samba from 3.5.0 to 4.2.0rc4 are vulnerable to an
   unexpected code execution vulnerability in the smbd file server
   daemon.

   A malicious client could send packets that may set up the stack in
   such a way that the freeing of memory in a subsequent anonymous
   netlogon packet could allow execution of arbitrary code. This code
   would execute with root privileges.


Changes since 4.0.24:
---------------------

o   Jeremy Allison <jra@samba.org>
    * BUG 11077: CVE-2015-0240: talloc free on uninitialized stack pointer
      in netlogon server could lead to security vulnerability.


o   Andreas Schneider <asn@samba.org>
    * BUG 11077: CVE-2015-0240: s3-netlogon: Make sure we do not deference
      a NULL pointer./auth: Make sure that creds_out is initialized with NULL.

                   Release Notes for Samba 4.0.19
                           June 23, 2014
                   ==============================


This is a security release in order to address
CVE-2014-0244 (Denial of service - CPU loop) and
CVE-2014-3493 (Denial of service - Server crash/memory corruption).

o  CVE-2014-0244:
   All current released versions of Samba are vulnerable to a denial of
   service on the nmbd NetBIOS name services daemon. A malformed packet
   can cause the nmbd server to loop the CPU and prevent any further
   NetBIOS name service.

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

o  CVE-2014-3493:
   All current released versions of Samba are affected by a denial of service
   crash involving overwriting memory on an authenticated connection to the
   smbd file server.


Changes since 4.0.18:
---------------------

o   Jeremy Allison <jra@samba.org>
    * BUG 10633: CVE-2014-0244: Fix nmbd denial of service.
    * BUG 10654: CVE-2014-3493: Fix segmentation fault in
      smbd_marshall_dir_entry()'s SMB_FIND_FILE_UNIX handler.

                   ==============================
                   Release Notes for Samba 4.0.16
                           March 11, 2014
                   ==============================


This is a security release in order to address
CVE-2013-4496 (Password lockout not enforced for SAMR password changes) and
CVE-2013-6442 (smbcacls can remove a file or directory ACL by mistake).

o  CVE-2013-4496:
   Samba versions 3.4.0 and above allow the administrator to implement
   locking out Samba accounts after a number of bad password attempts.

   However, all released versions of Samba did not implement this check for
   password changes, such as are available over multiple SAMR and RAP
   interfaces, allowing password guessing attacks.

o  CVE-2013-6442:
   Samba versions 4.0.0 and above have a flaw in the smbcacls command. If
   smbcacls is used with the "-C|--chown name" or "-G|--chgrp name"
   command options it will remove the existing ACL on the object being
   modified, leaving the file or directory unprotected.


Changes since 4.0.15:
---------------------

o   Jeremy Allison <jra@samba.org>
    * BUG 10327: CVE-2013-6442: ensure we don't lose an existing ACL when
      setting owner or group owner.


o   Andrew Bartlett <abartlet@samba.org>
    * BUG 10245: CVE-2013-4496: Enforce password lockout for SAMR password
      changes.


o   Stefan Metzmacher <metze@samba.org>
    * BUG 10245: CVE-2013-4496: Enforce password lockout for SAMR password
      changes.

                   ==============================
                   Release Notes for Samba 4.0.13
                          December 9, 2013
                   ==============================


This is a security release in order to address
CVE-2013-4408 (DCE-RPC fragment length field is incorrectly checked) and
CVE-2012-6150 (pam_winbind login without require_membership_of restrictions).

o  CVE-2013-4408:
   Samba versions 3.4.0 and above (versions 3.4.0 - 3.4.17, 3.5.0 -
   3.5.22, 3.6.0 - 3.6.21, 4.0.0 - 4.0.12 and including 4.1.2) are
   vulnerable to buffer overrun exploits in the client processing of
   DCE-RPC packets. This is due to incorrect checking of the DCE-RPC
   fragment length in the client code.

   This is a critical vulnerability as the DCE-RPC client code is part of
   the winbindd authentication and identity mapping daemon, which is
   commonly configured as part of many server installations (when joined
   to an Active Directory Domain). A malicious Active Directory Domain
   Controller or man-in-the-middle attacker impersonating an Active
   Directory Domain Controller could achieve root-level access by
   compromising the winbindd process.

   Samba server versions 3.4.0 - 3.4.17 and versions 3.5.0 - 3.5.22 are
   also vulnerable to a denial of service attack (server crash) due to a
   similar error in the server code of those versions.

   Samba server versions 3.6.0 and above (including all 3.6.x versions,
   all 4.0.x versions and 4.1.x) are not vulnerable to this problem.

   In addition range checks were missing on arguments returned from calls
   to the DCE-RPC functions LookupSids (lsa and samr), LookupNames (lsa and samr)
   and LookupRids (samr) which could also cause similar problems.

   As this was found during an internal audit of the Samba code there are
   no currently known exploits for this problem (as of December 9th 2013).

o  CVE-2012-6150:
   Winbind allows for the further restriction of authenticated PAM logins using
   the require_membership_of parameter. System administrators may specify a list
   of SIDs or groups for which an authenticated user must be a member of. If an
   authenticated user does not belong to any of the entries, then login should
   fail. Invalid group name entries are ignored.

   Samba versions 3.3.10, 3.4.3, 3.5.0 and later incorrectly allow login from
   authenticated users if the require_membership_of parameter specifies only
   invalid group names.

   This is a vulnerability with low impact. All require_membership_of group
   names must be invalid for this bug to be encountered.


Changes since 4.0.12:
---------------------

o   Jeremy Allison <jra@samba.org>
    * BUG 10185: CVE-2013-4408: Correctly check DCE-RPC fragment length field.


o   Stefan Metzmacher <metze@samba.org>
    * BUG 10185: CVE-2013-4408: Correctly check DCE-RPC fragment length field.


o   Noel Power <noel.power@suse.com>
    * BUGs 10300, 10306: CVE-2012-6150: Fail authentication if user isn't
      member of *any* require_membership_of specified groups.

                   ==============================
                   Release Notes for Samba 4.0.11
                          November 11, 2013
                   ==============================


This is a security release in order to address
CVE-2013-4475 (ACLs are not checked on opening an alternate
data stream on a file or directory) and
CVE-2013-4476 (Private key in key.pem world readable).

o  CVE-2013-4475:
   Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x,
   3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying
   file or directory ACL when opening an alternate data stream.

   According to the SMB1 and SMB2+ protocols the ACL on an underlying
   file or directory should control what access is allowed to alternate
   data streams that are associated with the file or directory.

   By default no version of Samba supports alternate data streams
   on files or directories.

   Samba can be configured to support alternate data streams by loading
   either one of two virtual file system modues (VFS) vfs_streams_depot or
   vfs_streams_xattr supplied with Samba, so this bug only affects Samba
   servers configured this way.

   To determine if your server is vulnerable, check for the strings
   "streams_depot" or "streams_xattr" inside your smb.conf configuration
   file.

o  CVE-2013-4476:
   In setups which provide ldap(s) and/or https services, the private
   key for SSL/TLS encryption might be world readable. This typically
   happens in active directory domain controller setups.


Changes since 4.0.10:
---------------------

o   Jeremy Allison <jra@samba.org>
    * BUGs 10234 + 10229: CVE-2013-4475: Fix access check verification on stream
      files.


o   Björn Baumbach <bb@sernet.de>
    * BUG 10234: CVE-2013-4476: Private key in key.pem world readable.

                   =============================
                   Release Notes for Samba 4.0.8
                          August 05, 2013
                   =============================


This is a security release in order to address
CVE-2013-4124 (Missing integer wrap protection in EA list reading can cause
server to loop with DOS).

o  CVE-2013-4124:
   All current released versions of Samba are vulnerable to a denial of
   service on an authenticated or guest connection. A malformed packet
   can cause the smbd server to loop the CPU performing memory
   allocations and preventing any further service.

   A connection to a file share, or a local account is needed to exploit
   this problem, either authenticated or unauthenticated if guest
   connections are allowed.

   This flaw is not exploitable beyond causing the code to loop
   allocating memory, which may cause the machine to exceed memory
   limits.


Changes since 4.0.7:
--------------------

o   Jeremy Allison <jra@samba.org>
    * BUG 10010: CVE-2013-4124: Missing integer wrap protection in EA list
      reading can cause server to loop with DOS.

Note about upgrading from older versions:
-----------------------------------------

It is still the case that there are printing tdbs (ntprinting.tdb, ntforms.tdb,
ntdrivers.tdb) which are in latin1 or other encodings. When updating from
Samba 3.5 or earlier to Samba 3.6 or 4.0 these tdbs need to be migrated to our
new registry based printing management.  This means during the migration we
also need to do charset conversion. This can only been done manually cause we don't
know in which encoding the tdb is. You have to specify the correct code page
for the conversion, see iconv -l and Wikipedia [1] for the available codepages.
The mostly used one is Windows Latin1 which is CP1252.

We've extended the 'net printing dump' and 'net printing migrate' commands to
define the encoding of the tdb. So you can correctly view the tdb with:

  net printing dump encoding=CP1252 /path/to/ntprinters.tdb

or migrate it with e.g.:

  net printing migrate encoding=CP1252 /path/to/ntprinters.tdb

If you migrate printers we suggest you do it in the following order.

ntforms.tdb
ntdrivers.tdb
ntprinting.tdb

Don't forget to rename, move or delete these files in /var/lib/samba after the
migration.

                   =============================
                   Release Notes for Samba 4.0.2
                         January 30, 2013
                   =============================


This is a security release in order to address
CVE-2013-0213 (Clickjacking issue in SWAT) and
CVE-2013-0214 (Potential XSRF in SWAT).

o  CVE-2013-0213:
   All current released versions of Samba are vulnerable to clickjacking in the
   Samba Web Administration Tool (SWAT). When the SWAT pages are integrated into
   a malicious web page via a frame or iframe and then overlaid by other content,
   an attacker could trick an administrator to potentially change Samba settings.

   In order to be vulnerable, SWAT must have been installed and enabled
   either as a standalone server launched from inetd or xinetd, or as a
   CGI plugin to Apache. If SWAT has not been installed or enabled (which
   is the default install state for Samba) this advisory can be ignored.

o  CVE-2013-0214:
   All current released versions of Samba are vulnerable to a cross-site
   request forgery in the Samba Web Administration Tool (SWAT). By guessing a
   user's password and then tricking a user who is authenticated with SWAT into
   clicking a manipulated URL on a different web page, it is possible to manipulate
   SWAT.

   In order to be vulnerable, the attacker needs to know the victim's password.
   Additionally SWAT must have been installed and enabled either as a standalone
   server launched from inetd or xinetd, or as a CGI plugin to Apache. If SWAT has
   not been installed or enabled (which is the default install state for Samba)
   this advisory can be ignored.


Changes since 4.0.1:
====================

o   Kai Blin <kai@samba.org>
    * BUG 9576: CVE-2013-0213: Fix clickjacking issue in SWAT.
    * BUG 9577: CVE-2013-0214: Fix potential XSRF in SWAT.

                   =============================
                   Release Notes for Samba 4.0.1
                          January 15, 2013
                   =============================


This is a security release in order to address CVE-2013-0172.

o  CVE-2013-0172:
   Samba 4.0.0 as an AD DC may provide authenticated users with write access
   to LDAP directory objects.

   In AD, Access Control Entries can be assigned based on the objectClass
   of the object.  If a user or a group the user is a member of has any
   access based on the objectClass, then that user has write access to that
   object.

   Additionally, if a user has write access to any attribute on the object,
   they may have access to write to all attributes.

   An important mitigation is that anonymous access is totally disabled by
   default.  The second important mitigation is that normal users are
   typically only given the problematic per-objectClass right via the
   "pre-windows 2000 compatible access" group, and Samba 4.0.0 incorrectly
   does not make "authenticated users" part of this group.

Changes since 4.0.0:
====================

o   Andrew Bartlett <abartlet@samba.org>
    * Bug 9554 - CVE-2013-0172 - Samba 4.0 as an AD DC may provide authenticated
      users with write access to LDAP directory objects.

                   =============================
                   Release Notes for Samba 4.0.0
                         December 11, 2012
                   =============================


This is is the first stable release of Samba 4.0.

This release contains the best of all of Samba's
technology parts, both a file server (that you can reasonably expect
to upgrade existing Samba 3.x releases to) and the AD domain
controller work previously known as 'Samba4'.

Major enhancements in Samba 4.0.0 include:

Active Directory services
=========================

Samba 4.0 supports the server-side of the Active Directory logon
environment used by Windows 2000 and later, so we can do full domain
join and domain logon operations with these clients.

Our Domain Controller (DC) implementation includes our own built-in
LDAP server and Kerberos Key Distribution Center (KDC) as well as the
Samba3-like logon services provided over CIFS.  We correctly generate
the infamous Kerberos PAC, and include it with the Kerberos tickets we
issue.

When running an AD DC, you only need to run 'samba' (not smbd/nmbd/winbindd),
as the required services are co-coordinated by this master binary.
The tool to administer the Active Directory services is called 'samba-tool'.

A short guide to setting up Samba 4 as an AD DC can be found on the wiki:

  http://wiki.samba.org/index.php/Samba4/HOWTO


File Services
=============

Samba 4.0.0 ships with two distinct file servers.  We now use the
file server from the Samba 3.x series 'smbd' for all file serving by
default.

Samba 4.0 also ships with the 'NTVFS' file server.  This file server
is what was used prior to the beta2 release of Samba 4.0, and is
tuned to match the requirements of an AD domain controller.  We
continue to support this, not only to provide continuity to
installations that have deployed it as part of an AD DC, but also as a
running example of the NT-FSA architecture we expect to move smbd to in
the longer term.

For pure file server work, the binaries users would expect from that
series (smbd, nmbd, winbindd, smbpasswd) continue to be available.


Domain Member Support
=====================

Domain member support in the 'samba' binary is in its infancy, and
is not comparable to the support found in 'winbindd'. As such, on
Samba domain member servers, the binaries 'smbd', 'nmbd' and 'winbindd'
are to be used, as known from Samba 3 domain member server setups.
The only exceptions from this rule are the cases which explicitly
require the 'samba' binary, namely running the ntvfs file server,
the CIFS proxy or OpenChange on a domain member.


DNS
===

As DNS is an integral part of Active Directory, we also provide two DNS
solutions, a simple internal DNS server for 'out of the box' configurations
and a more elaborate BIND plugin using the BIND DLZ mechanism in versions
9.8 and 9.9. During the provision, you can select which backend to use.
With the internal backend, your DNS server is good to go.
If you chose the BIND_DLZ backend, a configuration file will be generated
for bind to make it use this plugin, as well as a file explaining how to
set up bind.


NTP
===

To provide accurate timestamps to Windows clients, we integrate with
the NTP project to provide secured NTP replies.  To use you need to
start ntpd and configure it with the 'restrict ... ms-sntp' and
ntpsigndsocket options.


Python Scripting Interface
==========================

A new scripting interface has been added to Samba 4, allowing
Python programs to interface to Samba's internals, and many tools and
internal workings of the DC code is now implemented in python.


Known Issues
============

- Replication of DNS data from one AD server to another may not work.
  The DNS data used by the internal DNS server and bind9_dlz is stored
  in an application partition in our directory.  The replication of
  this partition is not yet reliable.

- Replication may fail on FreeBSD due to getaddrinfo() rejecting names
  containing _.  A workaround will be in a future release.

- samba_upgradeprovision should not be run when upgrading to this release
  from a recent release.  No important database format changes have
  been made since alpha16.

- Installation on systems without a system iconv (and developer
  headers at compile time) is known to cause errors when dealing with
  non-ASCII characters.

- There is no NetBIOS browsing support (network neighbourhood)
  available for the AD domain controller.  (Support in nmbd and smbd
  for classic domains and member/standalone servers is unchanged).

- Clock Synchronisation is critical.  Many 'wrong password' errors are
  actually due to Kerberos objecting to a clock skew between client
  and server.  (The NTP work in the previous alphas are partly to assist
  with this problem).

- The DRS replication code may fail.  Please contact the team if you
  experience issues with DRS replication, as we have fixed many issues
  here in response to feedback from our production users.

- Linux inotify will now only be supported on systems where glibc also supports
  it (for details, please refer to bug #8850).


Upgrading
=========

Users upgrading from Samba 3.x domain controllers and wanting to use
Samba 4.0 as an AD DC should use the 'samba-tool domain
classicupgrade' command.  See the wiki for more details:
https://wiki.samba.org/index.php/Samba4/samba3upgrade/HOWTO.

Users upgrading from Samba 4.0 alpha and beta releases since alpha15
should run 'samba-tool dbcheck --cross-ncs --fix' before re-starting
Samba.  Users upgrading from earlier alpha releases should contact the
team for advice.

Users upgrading an AD DC from any previous release should run
'samba-tool ntacl sysvolreset' to re-sync ACLs on the sysvol share
with those matching the GPOs in LDAP and the defaults from an initial
provision.  This will set an underlying POSIX ACL if required (eg not
using the NTVFS file server).

If you used the BIND9_FLATFILE or BIND9_DLZ features,
you'll have to add '-dns' to the 'server services' option,
as the internal dns server (SAMBA_INTERNAL) is the default now.


Supported features
==================

A whitepaper of currently (un-)supported features is available on the wiki:

CHANGES SINCE 4.0.0rc5
======================

In this release candidate, we have a significant number of improvements
to our Access Control List (ACL) code, particularly for the Active
Directory Domain Controller, but also in our general purpose file
server.

These changes are important, as they enable Group Policy Objects to work
correctly, allow administrators to impose restrictions on some users
reading certain parts of the directory and correctly propagating
inherited ACLs down the LDAP directory tree.

Users of the Active Directory Domain Controller upgrading from any
previous release should run 'samba-tool ntacl sysvolreset' to re-sync
ACLs on the sysvol share with those matching the GPOs in LDAP and the
defaults from an initial provision.  This will set an underlying POSIX
ACL if required.

The ACLs in the Active Directory are also checked on searches by default.
The automatic inheritance of ACLs is also correctly recalculated on
changes now.

CHANGES SINCE 4.0.0rc4
======================

With this release candidate the location of the socket samba accepts
connections from NTPd has changed, as has the enforced permissions.

This means the ntp.conf will need to change from (eg)

ntpsigndsocket /usr/local/samba/var/run/ntp_signd/

to

ntpsigndsocket /usr/local/samba/var/lib/ntp_signd/

To use the socket with ntp on a system with an ntp user and group, you must
run:

chgrp ntp /usr/local/samba/var/lib/ntp_signd/
