2 Release Notes for Samba 4.1.17
3 February 23, 2015
4 ==============================
7 This is a security release in order to address CVE-2015-0240 (Unexpected
8 code execution in smbd).
10 o CVE-2015-0240:
11 All versions of Samba from 3.5.0 to 4.2.0rc4 are vulnerable to an
12 unexpected code execution vulnerability in the smbd file server
13 daemon.
15 A malicious client could send packets that may set up the stack in
16 such a way that the freeing of memory in a subsequent anonymous
17 netlogon packet could allow execution of arbitrary code. This code
18 would execute with root privileges.
21 Changes since 4.1.16:
22 ---------------------
24 o Jeremy Allison <jra@samba.org>
25 * BUG 11077: CVE-2015-0240: talloc free on uninitialized stack pointer

690 Release Notes for Samba 4.1.9
691 June 23, 2014
692 =============================
695 This is a security release in order to address
696 CVE-2014-0244 (Denial of service - CPU loop) and
697 CVE-2014-3493 (Denial of service - Server crash/memory corruption).
699 o CVE-2014-0244:
700 All current released versions of Samba are vulnerable to a denial of
701 service on the nmbd NetBIOS name services daemon. A malformed packet
702 can cause the nmbd server to loop the CPU and prevent any further
703 NetBIOS name service.
705 This flaw is not exploitable beyond causing the code to loop expending
706 CPU resources.
708 o CVE-2014-3493:
709 All current released versions of Samba are affected by a denial of service
710 crash involving overwriting memory on an authenticated connection to the
711 smbd file server.
714 Changes since 4.1.8:
715 --------------------
717 o Jeremy Allison <jra@samba.org>
718 * BUG 10633: CVE-2014-0244: Fix nmbd denial of service.
719 * BUG 10654: CVE-2014-3493: Fix segmentation fault in

976 =============================
977 Release Notes for Samba 4.1.6
978 March 11, 2014
979 =============================
982 This is a security release in order to address
983 CVE-2013-4496 (Password lockout not enforced for SAMR password changes) and
984 CVE-2013-6442 (smbcacls can remove a file or directory ACL by mistake).
986 o CVE-2013-4496:
987 Samba versions 3.4.0 and above allow the administrator to implement
988 locking out Samba accounts after a number of bad password attempts.
990 However, all released versions of Samba did not implement this check for
991 password changes, such as are available over multiple SAMR and RAP
992 interfaces, allowing password guessing attacks.
994 o CVE-2013-6442:
995 Samba versions 4.0.0 and above have a flaw in the smbcacls command. If
996 smbcacls is used with the "-C|--chown name" or "-G|--chgrp name"
997 command options it will remove the existing ACL on the object being
998 modified, leaving the file or directory unprotected.
1001 Changes since 4.1.5:
1002 --------------------
1004 o Jeremy Allison <jra@samba.org>
1005 * BUG 10327: CVE-2013-6442: ensure we don't lose an existing ACL when
1006 setting owner or group owner.

1011 changes.
1014 o Stefan Metzmacher <metze@samba.org>
1015 * BUG 10245: CVE-2013-4496: Enforce password lockout for SAMR password

1256 vulnerable to buffer overrun exploits in the client processing of
1257 DCE-RPC packets. This is due to incorrect checking of the DCE-RPC
1258 fragment length in the client code.
1260 This is a critical vulnerability as the DCE-RPC client code is part of
1261 the winbindd authentication and identity mapping daemon, which is
1262 commonly configured as part of many server installations (when joined
1263 to an Active Directory Domain). A malicious Active Directory Domain
1264 Controller or man-in-the-middle attacker impersonating an Active
1265 Directory Domain Controller could achieve root-level access by
1266 compromising the winbindd process.
1268 Samba server versions 3.4.0 - 3.4.17 and versions 3.5.0 - 3.5.22 are
1269 also vulnerable to a denial of service attack (server crash) due to a
1270 similar error in the server code of those versions.
1272 Samba server versions 3.6.0 and above (including all 3.6.x versions,
1273 all 4.0.x versions and 4.1.x) are not vulnerable to this problem.
1275 In addition range checks were missing on arguments returned from calls
1276 to the DCE-RPC functions LookupSids (lsa and samr), LookupNames (lsa and samr)
1277 and LookupRids (samr) which could also cause similar problems.
1279 As this was found during an internal audit of the Samba code there are
1280 no currently known exploits for this problem (as of December 9th 2013).
1282 o CVE-2012-6150:
1283 Winbind allows for the further restriction of authenticated PAM logins using
1284 the require_membership_of parameter. System administrators may specify a list
1285 of SIDs or groups for which an authenticated user must be a member of. If an
1286 authenticated user does not belong to any of the entries, then login should
1287 fail. Invalid group name entries are ignored.
1289 Samba versions 3.3.10, 3.4.3, 3.5.0 and later incorrectly allow login from
1290 authenticated users if the require_membership_of parameter specifies only
1291 invalid group names.
1293 This is a vulnerability with low impact. All require_membership_of group
1294 names must be invalid for this bug to be encountered.

1429 Release Notes for Samba 4.1.1
1430 November 11, 2013
1431 =============================
1434 This is a security release in order to address
1435 CVE-2013-4475 (ACLs are not checked on opening an alternate
1436 data stream on a file or directory) and
1437 CVE-2013-4476 (Private key in key.pem world readable).
1439 o CVE-2013-4475:
1440 Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x,
1441 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying
1442 file or directory ACL when opening an alternate data stream.
1444 According to the SMB1 and SMB2+ protocols the ACL on an underlying
1445 file or directory should control what access is allowed to alternate
1446 data streams that are associated with the file or directory.
1448 By default no version of Samba supports alternate data streams
1449 on files or directories.
1451 Samba can be configured to support alternate data streams by loading
1452 either one of two virtual file system modues (VFS) vfs_streams_depot or
1453 vfs_streams_xattr supplied with Samba, so this bug only affects Samba
1454 servers configured this way.
1456 To determine if your server is vulnerable, check for the strings
1457 "streams_depot" or "streams_xattr" inside your smb.conf configuration
1458 file.
1460 o CVE-2013-4476:
1461 In setups which provide ldap(s) and/or https services, the private
1462 key for SSL/TLS encryption might be world readable. This typically
1463 happens in active directory domain controller setups.
1466 Changes since 4.1.0:

1470 * BUGs 10234 + 10229: CVE-2013-4475: Fix access check verification on stream
1471 files.
1474 o Björn Baumbach <bb@sernet.de>

1502 Release Notes for Samba 4.1.0
1503 October 11, 2013
1504 =============================
1507 This is is the first stable release of Samba 4.1.
1509 Samba 4.1 will be the next version of the Samba suite and includes
1510 all the technology found in both the Samba4 series and the stable 3.x
1511 series. The primary additional features over Samba 3.6 are
1512 support for the Active Directory logon protocols used by Windows 2000
1513 and above.
1515 Major enhancements in Samba 4.1.0 include:
1517 Client tools support SMB2/3
1518 ===========================
1520 Samba 4.1.0 contains the first release of our client tools
1521 and client library that work over the new protocols SMB2 or SMB3.
1522 Note that SMB3 only works either to a Samba server version 4.0.0
1523 or above, or to a Windows Server running Windows 2012 or Windows 8.
1525 The default protocol for smbclient and smbcacls is still
1526 SMB1 (the NT1 protocol dialect). An SMB2 or SMB3 connection
1527 can be selected in one of two ways. The easiest way to test
1528 the new protocol connection is to add the -mMAX_PROTOCOL
1529 command line switch to either smbclient or smbcacls.
1531 For example, to connect using SMB3 with smbclient a user
1532 would type:
1534 smbclient //server/share -Uuser%password -mSMB3
1536 Another example of connecting using SMB2 using smbcacls
1537 would be:
1539 smbcacls //server/share -Uuser%password -mSMB2 filename
1541 Note that when connecting using SMB2 or SMB3 protocols
1542 the UNIX extensions are no longer available inside the
1543 smbclient command set. This is due to UNIX extensions
1544 not yet being defined for the SMB2 or SMB3 protocols.
1546 The second way to select SMB2 or SMB3 connections is to
1547 set the "client max protocol" parameter in the [global]
1548 section of your smb.conf.
1550 Setting this parameter will cause all client connections
1551 from Samba and its client tools to offer the requested
1552 max protocol to a server on every connection request.
1554 For example, to cause all client tools (including winbindd,
1555 rpcclient, and the libsmbclient library) to attempt use SMB3
1556 by default add the line:
1558 client max protocol = SMB3
1560 to the [global] section of your smb.conf. This has not
1561 been as widely tested as the -mPROTOCOL options, but
1562 is intended to work correctly in the final release of
1563 4.1.0.
1565 Encrypted transport
1566 ===================
1568 Although Samba servers have supported encrypted transport
1569 connections using the UNIX extensions for many years,
1570 selecting SMB3 transport allows encrypted transport
1571 connections to Windows servers that support SMB3, as
1572 well as Samba servers.
1574 In order to enable this, add the "-e" option to the
1575 smbclient command line.
1577 For example, to connect to a Windows 2012 server over
1578 SMB3 and select an encrypted transport you would use
1579 the following command line:
1581 smbclient //Win2012Server/share -Uuser%password -mSMB3 -e
1584 Directory database replication (AD DC mode)
1585 ===========================================
1587 Directory replication has been reworked in order to improve the
1588 correctness and efficiency.
1589 As a net effect of it, replication with other domain controllers with
1590 a heavily modified schema is now possible (ie. Windows 2012 DCs or
1591 other Windows DC with exchange installed) and replication didn't fail
1592 anymore in such environments.
1595 Server-Side Copy Support
1596 ========================
1598 Samba 4.1.0 adds support for server-side copy operations via the SMB2
1599 FSCTL_SRV_COPYCHUNK request. Clients making use of server-side copy
1600 support, such as Windows Server 2012, should experience considerable
1601 performance improvements for file copy operations, as file data need not
1602 traverse the network.
1603 This feature is enabled by default on the smbd file server.
1606 Btrfs Filesystem Integration
1607 ============================
1609 The Btrfs VFS module provided with Samba 4.1.0 further improves the
1610 performance of server-side copy operations on shares backed by a Btrfs
1611 filesystem. It does so by allowing multiple files to share the same
1612 on-disk extents, avoiding the unnecessary duplication of source and
1613 destination file data during a server-side copy operation.
1615 This feature can be explicitly enabled on smbd shares backed by a Btrfs
1616 filesystem with the smb.conf parameter:
1617 vfs objects = btrfs
1620 REMOVED COMPONENTS
1621 ==================
1623 The Samba Web Administration Tool (SWAT) has been removed.
1624 Details why SWAT has been removed can be found on the samba-technical mailing
1625 list:
