485 Release Notes for Samba 4.1.6
487 =============================
490 This is a security release in order to address
491 CVE-2013-4496 (Password lockout not enforced for SAMR password changes) and
492 CVE-2013-6442 (smbcacls can remove a file or directory ACL by mistake).
495 Samba versions 3.4.0 and above allow the administrator to implement
496 locking out Samba accounts after a number of bad password attempts.
498 However, all released versions of Samba did not implement this check for
499 password changes, such as are available over multiple SAMR and RAP
500 interfaces, allowing password guessing attacks.
503 Samba versions 4.0.0 and above have a flaw in the smbcacls command. If
504 smbcacls is used with the "-C|--chown name" or "-G|--chgrp name"
505 command options it will remove the existing ACL on the object being
506 modified, leaving the file or directory unprotected.

752 Release Notes for Samba 4.1.3
754 =============================
757 This is a security release in order to address
758 CVE-2013-4408 (DCE-RPC fragment length field is incorrectly checked) and
759 CVE-2012-6150 (pam_winbind login without require_membership_of restrictions).
762 Samba versions 3.4.0 and above (versions 3.4.0 - 3.4.17, 3.5.0 -
763 3.5.22, 3.6.0 - 3.6.21, 4.0.0 - 4.0.12 and including 4.1.2) are
764 vulnerable to buffer overrun exploits in the client processing of
765 DCE-RPC packets. This is due to incorrect checking of the DCE-RPC
766 fragment length in the client code.
768 This is a critical vulnerability as the DCE-RPC client code is part of
769 the winbindd authentication and identity mapping daemon, which is
770 commonly configured as part of many server installations (when joined
771 to an Active Directory Domain). A malicious Active Directory Domain
772 Controller or man-in-the-middle attacker impersonating an Active
773 Directory Domain Controller could achieve root-level access by
774 compromising the winbindd process.
776 Samba server versions 3.4.0 - 3.4.17 and versions 3.5.0 - 3.5.22 are
777 also vulnerable to a denial of service attack (server crash) due to a
778 similar error in the server code of those versions.
780 Samba server versions 3.6.0 and above (including all 3.6.x versions,
781 all 4.0.x versions and 4.1.x) are not vulnerable to this problem.
783 In addition range checks were missing on arguments returned from calls
784 to the DCE-RPC functions LookupSids (lsa and samr), LookupNames (lsa and samr)
785 and LookupRids (samr) which could also cause similar problems.
787 As this was found during an internal audit of the Samba code there are
788 no currently known exploits for this problem (as of December 9th 2013).
791 Winbind allows for the further restriction of authenticated PAM logins using
792 the require_membership_of parameter. System administrators may specify a list
793 of SIDs or groups for which an authenticated user must be a member of. If an
794 authenticated user does not belong to any of the entries, then login should
795 fail. Invalid group name entries are ignored.
797 Samba versions 3.3.10, 3.4.3, 3.5.0 and later incorrectly allow login from
798 authenticated users if the require_membership_of parameter specifies only
801 This is a vulnerability with low impact. All require_membership_of group
802 names must be invalid for this bug to be encountered.

937 Release Notes for Samba 4.1.1
939 =============================
942 This is a security release in order to address
943 CVE-2013-4475 (ACLs are not checked on opening an alternate
944 data stream on a file or directory) and
945 CVE-2013-4476 (Private key in key.pem world readable).
948 Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x,
949 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying
950 file or directory ACL when opening an alternate data stream.
952 According to the SMB1 and SMB2+ protocols the ACL on an underlying
953 file or directory should control what access is allowed to alternate
954 data streams that are associated with the file or directory.
956 By default no version of Samba supports alternate data streams
957 on files or directories.
959 Samba can be configured to support alternate data streams by loading
960 either one of two virtual file system modues (VFS) vfs_streams_depot or
961 vfs_streams_xattr supplied with Samba, so this bug only affects Samba
962 servers configured this way.
964 To determine if your server is vulnerable, check for the strings
965 "streams_depot" or "streams_xattr" inside your smb.conf configuration
969 In setups which provide ldap(s) and/or https services, the private
970 key for SSL/TLS encryption might be world readable. This typically
971 happens in active directory domain controller setups.

1003 ======================================================================
1006 ----------------------------------------------------------------------
1009 =============================
1010 Release Notes for Samba 4.1.0
1012 =============================
1015 This is is the first stable release of Samba 4.1.
1017 Samba 4.1 will be the next version of the Samba suite and includes
1018 all the technology found in both the Samba4 series and the stable 3.x
1019 series. The primary additional features over Samba 3.6 are
1020 support for the Active Directory logon protocols used by Windows 2000
1023 Major enhancements in Samba 4.1.0 include:
1025 Client tools support SMB2/3
1026 ===========================
1028 Samba 4.1.0 contains the first release of our client tools
1029 and client library that work over the new protocols SMB2 or SMB3.
1030 Note that SMB3 only works either to a Samba server version 4.0.0
1031 or above, or to a Windows Server running Windows 2012 or Windows 8.
1033 The default protocol for smbclient and smbcacls is still
1034 SMB1 (the NT1 protocol dialect). An SMB2 or SMB3 connection
1035 can be selected in one of two ways. The easiest way to test
1036 the new protocol connection is to add the -mMAX_PROTOCOL
1037 command line switch to either smbclient or smbcacls.
1039 For example, to connect using SMB3 with smbclient a user
1042 smbclient //server/share -Uuser%password -mSMB3
1044 Another example of connecting using SMB2 using smbcacls
1047 smbcacls //server/share -Uuser%password -mSMB2 filename
1049 Note that when connecting using SMB2 or SMB3 protocols
1050 the UNIX extensions are no longer available inside the
1051 smbclient command set. This is due to UNIX extensions
1052 not yet being defined for the SMB2 or SMB3 protocols.
1054 The second way to select SMB2 or SMB3 connections is to
1055 set the "client max protocol" parameter in the [global]
1056 section of your smb.conf.
1058 Setting this parameter will cause all client connections
1059 from Samba and its client tools to offer the requested
1060 max protocol to a server on every connection request.
1062 For example, to cause all client tools (including winbindd,
1063 rpcclient, and the libsmbclient library) to attempt use SMB3
1064 by default add the line:
1066 client max protocol = SMB3
1068 to the [global] section of your smb.conf. This has not
1069 been as widely tested as the -mPROTOCOL options, but
1070 is intended to work correctly in the final release of
1076 Although Samba servers have supported encrypted transport
1077 connections using the UNIX extensions for many years,
1078 selecting SMB3 transport allows encrypted transport
1079 connections to Windows servers that support SMB3, as
1080 well as Samba servers.
1082 In order to enable this, add the "-e" option to the
1083 smbclient command line.
1085 For example, to connect to a Windows 2012 server over
1086 SMB3 and select an encrypted transport you would use
1087 the following command line:
1089 smbclient //Win2012Server/share -Uuser%password -mSMB3 -e
1092 Directory database replication (AD DC mode)
1093 ===========================================
1095 Directory replication has been reworked in order to improve the
1096 correctness and efficiency.
1097 As a net effect of it, replication with other domain controllers with
1098 a heavily modified schema is now possible (ie. Windows 2012 DCs or
1099 other Windows DC with exchange installed) and replication didn't fail
1100 anymore in such environments.
1103 Server-Side Copy Support
1104 ========================
1106 Samba 4.1.0 adds support for server-side copy operations via the SMB2
1107 FSCTL_SRV_COPYCHUNK request. Clients making use of server-side copy
1108 support, such as Windows Server 2012, should experience considerable
1109 performance improvements for file copy operations, as file data need not
1110 traverse the network.
1111 This feature is enabled by default on the smbd file server.
1114 Btrfs Filesystem Integration
1115 ============================
1117 The Btrfs VFS module provided with Samba 4.1.0 further improves the
1118 performance of server-side copy operations on shares backed by a Btrfs
1119 filesystem. It does so by allowing multiple files to share the same
1120 on-disk extents, avoiding the unnecessary duplication of source and
1121 destination file data during a server-side copy operation.
1123 This feature can be explicitly enabled on smbd shares backed by a Btrfs
1124 filesystem with the smb.conf parameter:
1131 The Samba Web Administration Tool (SWAT) has been removed.
1132 Details why SWAT has been removed can be found on the samba-technical mailing
