8 Release Notes for Samba 3.0.5
10 =============================
12 ######################## SECURITY RELEASE ########################
14 Summary: Multiple Potential Buffer Overruns in Samba 3.0.x
15 CVE ID: CAN-2004-0600, CAN-2004-0686
16 (http://cve.mitre.org/)
19 This is the latest stable release of Samba. This is the version
20 that production Samba servers should be running for all current
23 It has been confirmed that versions of Samba 3 prior to v3.0.5
24 are vulnerable to two potential buffer overruns. The individual
25 details are given below.
32 Affected Versions: Samba 3.0.2 and later
34 The internal routine used by the Samba Web Administration
35 Tool (SWAT v3.0.2 and later) to decode the base64 data
36 during HTTP basic authentication is subject to a buffer
37 overrun caused by an invalid base64 character. It is
38 recommended that all Samba v3.0.2 or later installations
39 running SWAT either (a) upgrade to v3.0.5, or (b) disable
40 the swat administration service as a temporary workaround.
42 This same code is used internally to decode the
43 sambaMungedDial attribute value when using the ldapsam
44 passdb backend. While we do not believe that the base64
45 decoding routines used by the ldapsam passdb backend can
46 be exploited, sites using an LDAP directory service with
47 Samba are strongly encouraged to verify that the DIT only
48 allows write access to sambaSamAccount attributes by a
49 sufficiently authorized user.
51 The Samba Team would like to heartily thank Evgeny Demidov
52 for analyzing and reporting this bug.
59 Affected Versions: Samba 3.0.0 and later
61 A buffer overrun has been located in the code used to support
62 the 'mangling method = hash' smb.conf option. Please be aware
63 that the default setting for this parameter is 'mangling method
64 = hash2' and therefore not vulnerable.
66 Affected Samba 3 installations can avoid this possible security
67 bug by using the default hash2 mangling method. Server
68 installations requiring the hash mangling method are encouraged
69 to upgrade to Samba 3.0.5.

672 Samba 3.0.2a is a minor patch release for the 3.0.2 code base
673 to address, in particular, a problem when using pdbedit to
674 sanitize (--force-initialized-passwords) Samba's tdbsam
675 backend. This is the latest stable release of Samba. This
676 is the version that all production Samba servers should be
677 running for all current bug-fixes.
679 ******************* Attention! Achtung! Kree! *********************
681 Beginning with Samba 3.0.2, passwords for accounts with a last
682 change time (LCT-XXX in smbpasswd, sambaPwdLastSet attribute in
683 ldapsam, etc...) of zero (0) will be regarded as uninitialized
684 strings. This will cause authentication to fail for such
685 accounts. If you have valid passwords that meet this criteria,
686 you must update the last change time to a non-zero value. If you
687 do not, then 'pdbedit --force-initialized-passwords' will disable
688 these accounts and reset the password hashes to a string of X's.
690 ******************* Attention! Achtung! Kree! *********************

742 Release Notes for Samba 3.0.2
744 =============================
746 It has been confirmed that previous versions of Samba 3.0 are
747 susceptible to a password initialization bug that could grant an
748 attacker unauthorized access to a user account created by the
749 mksmbpasswd.sh shell script.
751 The Common Vulnerabilities and Exposures project (cve.mitre.org)
752 has assigned the name CAN-2004-0082 to this issue.
754 Samba administrators not wishing to upgrade to the current
755 version should download the 3.0.2 release, build the pdbedit
758 root# pdbedit-3.0.2 --force-initialized-passwords
760 This will disable all accounts not possessing a valid password
761 (e.g. the password field has been set a string of X's).
763 Samba servers running 3.0.2 are not vulnerable to this bug
764 regardless of whether or not pdbedit has been used to sanitize
767 Some of the more visible bugs in 3.0.1 addressed in the 3.0.2
770 o Joining a Samba domain from Pre-SP2 Windows 2000 clients.
771 o Logging onto a Samba domain from Windows XP clients.
772 o Problems with the %U and %u smb.conf variables in relation to
773 Windows 9x/ME clients.
774 o Kerberos failures due to an invalid in memory keytab detection
776 o Updates to the ntlm_auth tool.
777 o Fixes for various SMB signing errors.
778 o Better separation of WINS and DNS queries for domain controllers.
779 o Issues with nss_winbind FreeBSD and Solaris.
780 o Several crash bugs in smbd and winbindd.
781 o Output formatting fixes for smbclient for better compatibility
782 with scripts based on the 2.2 version.

1259 know the winbindd pipe protocol.
1260 o Adds a variant of the winbindd_getgroups() call called
1261 winbindd_getusersids() that provides direct SID->SIDs listing of
1262 a users supplementary groups. This is enough to allow non-Samba
1263 applications to do ACL checking.
1264 o Make sure we don't append the 'ldap suffix' when writing out the
1265 'ldap XXX suffix' values in SWAT (bug 328).
1266 o Fix renames across file systems.
1267 o Ensure that items in a list of strings containing whitespace are
1268 written out surrounded by single quotes. This means that both
1269 double and single quotes are now used to surround strings in
1271 o Enable SWAT to correctly determine if winbindd is running (bug
1273 o Include WWW-Authenticate field in 401 response for bad auth
1275 o Add support for NTLM2 (NTLMv2 session security).
1276 o Add support for variable-length session keys.
1277 o More privilege fixes for group enumeration in LDAP (bug 281).
1278 o Use the dns name (or IP) as the originating client name when
1279 using CUPS (bug 467).
1280 o Fix various SMB signing bugs.
1281 o Fix ACL propagation on a DFS root (bug 263).
1282 o Disable NTLM2 for RPC pipes.
1283 o Allow the client to specify the NTLM2 flags got NTLMSSP
1285 o Change the name of the job passed off to cups from "Test Page"
1286 to "smbprn.00000033 Test Page" so that we can get the smb
1287 jobid back. This allow users to delete jobs with cups printing
1288 backend (partial work on bug 770).
1289 o Fix build of winbindd with static pdb modules.
1290 o Retrieve the correct ACL group bits if the file has an ACL
1292 o Implement "net rpc group members": Get members of a domain group
1293 in human-readable format.
1294 o Add MacOSX (Darwin) specific charset module code.
1295 o Use samr_dispinfo(level == 1) for enumerating domain users so we
1296 can include the full name in gecos field (bug 587).
1297 o Add support for winbind's NSS library on FeeeBSD 5.1 (bug 797).
1298 o Implement 'net rpc group list [global|local|builtin]*' for a
1299 select listing of the respective user databases.
1300 o Don't automatically set NT status code flag unless client tells
1302 o Add 'net status [sessions|shares] [parseable]'.
1303 o Don't mistake pre-existing UNIX jobs for smb jobs (remainder of
1305 o Add 'Replicator' and 'RAS Servers' to list of builtin SIDs
1307 o Fix inverted logic in hosts allow/deny checks caused by
1308 s/strcmp/strequal/ (bug 846).
1309 o Implement correct version SamrRemoveSidForeignDomain() (bug 252).
1310 o Fix typo in 'hash' mangling algorithm.
1311 o Support munged dial for ldapsam (bug 800).
1312 o Fix process_incoming_data() to return the number of bytes handled
1313 this call whether we have a complete PDU or not; fixes bug
1314 with multiple PDU request rpc's broken over SMBwriteX calls
1316 o Fix incorrect smb flags2 for connections to pre-NT servers
1317 (causes smbclient to fail to OS2 for example) (bug 821).
1318 o Update version string in smbldap-tools Makefile to 0.8.2.
1319 o Correct a problem with "net rpc vampire" mis-parsing the
1320 alias member info reply.
1321 o Ensure the ${libdir} is created by the installclientlib script.
1322 o Fix detection of Windows 2003 client architecture in the smb.conf
1324 o Ensure that smbd calls the add user script for a missing UNIX
1325 user on kerberos auth call (bug 445).
1326 o Fix bugs in hosts allow/deny when using a mismatched
1327 network/netmask pair.

1338 o Fix UNISTR2 length bug in LsaQueryInfo(3) that caused SID
1339 resolution to fail on local files on on domain members
1341 o Fix uninitialized variable in passdb.c.

1354 The original 3.0.0 release notes follow
1355 =======================================
1356 WHATS NEW IN Samba 3.0.0
1358 =======================================
1364 1) Active Directory support. Samba 3.0 is now able to
1365 join a ADS realm as a member server and authenticate
1366 users using LDAP/Kerberos.
1368 2) Unicode support. Samba will now negotiate UNICODE on the wire
1369 and internally there is now a much better infrastructure for
1370 multi-byte and UNICODE character sets.
1372 3) New authentication system. The internal authentication system
1373 has been almost completely rewritten. Most of the changes are
1374 internal, but the new auth system is also very configurable.
1376 4) New default filename mangling system.
1378 5) A new "net" command has been added. It is somewhat similar to
1379 the "net" command in windows. Eventually we plan to replace
1380 numerous other utilities (such as smbpasswd) with subcommands
1383 6) Samba now negotiates NT-style status32 codes on the wire. This
1384 improves error handling a lot.
1386 7) Better Windows 2000/XP/2003 printing support including publishing
1387 printer attributes in active directory.
1389 8) New loadable module support for passdb backends and character
1392 9) New default dual-daemon winbindd support for better performance.
1394 10) Support for migrating from a Windows NT 4.0 domain to a Samba
1395 domain and maintaining user, group and domain SIDs.
1397 11) Support for establishing trust relationships with Windows NT 4.0
1400 12) Initial support for a distributed Winbind architecture using
1401 an LDAP directory for storing SID to uid/gid mappings.
1403 13) Major updates to the Samba documentation tree.
1405 14) Full support for client and server SMB signing to ensure
1406 compatibility with default Windows 2003 security settings.
1408 15) Improvement of ACL mapping features based on code donated by
1409 Andreas Grünbacher.
1412 Plus lots of other improvements!
1415 Additional Documentation
1416 ------------------------
1418 Please refer to Samba documentation tree (included in the docs/
1419 subdirectory) for extensive explanations of installing, configuring
1420 and maintaining Samba 3.0 servers and clients. It is advised to
1421 begin with the Samba-HOWTO-Collection for overviews and specific
1422 tasks (the current book is up to approximately 400 pages) and to
1423 refer to the various man pages for information on individual options.
1425 We are very glad to be able to include the second edition of
1426 "Using Samba" by Jay Ts, Robert Eckstein, and David Collier-Brown
1427 (O'Reilly & Associates) in this release. The book is available
1428 on-line at http://samba.org/samba/docs/ and is included with
1429 the Samba Web Administration Tool (SWAT). Thanks to the authors and
1430 publisher for making "Using Samba" under the GNU Free Documentation
1434 ######################################################################
1435 Upgrading from a previous Samba 3.0 beta
1436 ########################################
1438 Beginning with Samba 3.0.0beta3, the RID allocation functions
1439 have been moved into winbindd. Previously these were handled
1440 by each passdb backend. This means that winbindd must be running
1441 to automatically allocate RIDs for users and/or groups. Otherwise,
1442 smbd will use the 2.2 algorithm for generating new RIDs.
1444 If you are using 'passdb backend = tdbsam' with a previous Samba
1445 3.0 beta release (or possibly alpha), it may be necessary to
1446 move the RID_COUNTER entry from /usr/local/samba/private/passdb.tdb
1447 to winbindd_idmap.tdb. To do this:
1449 1) Ensure that winbindd_idmap.tdb exists (launch winbindd at least
1451 2) build tdbtool by executing 'make tdbtool' in the source/tdb/
1453 3) run: (note that 'tdb>' is the tool's prompt for input)
1455 root# ./tdbtool /usr/local/samba/private/passdb.tdb
1456 tdb> show RID_COUNTER
1460 [000] 0A 52 00 00 .R.
1462 tdb> move RID_COUNTER /usr/local/samba/var/locks/winbindd_idmap.tdb
1466 If you are using 'passdb backend = ldapsam', it will be necessary to
1467 store idmap entries in the LDAP directory as well (i.e. idmap backend
1468 = ldap). Refer to the 'net idmap' command for more information on
1469 migrating SID<->UNIX id mappings from one backend to another.
1471 If the RID_COUNTER record does not exist, then these instructions are
1472 unneccessary and the new RID_COUNTER record will be correctly generated

1652 This section contains brief descriptions of any new databases
1653 introduced in Samba 3.0. Please remember to backup your existing
1654 ${lock directory}/*tdb before upgrading to Samba 3.0. Samba will
1655 upgrade databases as they are opened (if necessary), but downgrading
1656 from 3.0 to 2.2 is an unsupported path.
1658 Name Description Backup?
1659 ---- ----------- -------
1660 account_policy User policy settings yes
1661 gencache Generic caching db no
1662 group_mapping Mapping table from Windows yes
1663 groups/SID to unix groups
1664 winbindd_idmap ID map table from SIDS to UNIX yes
1666 namecache Name resolution cache entries no
1667 netsamlogon_cache Cache of NET_USER_INFO_3 structure no

1671 command' created on a per print
1673 registry Read-only samba registry skeleton no
1674 that provides support for exporting
1675 various db tables via the winreg RPCs
1681 The following issues are known changes in behavior between Samba 2.2 and
1682 Samba 3.0 that may affect certain installations of Samba.
1684 1) When operating as a member of a Windows domain, Samba 2.2 would
1685 map any users authenticated by the remote DC to the 'guest account'
1686 if a uid could not be obtained via the getpwnam() call. Samba 3.0
1687 rejects the connection as NT_STATUS_LOGON_FAILURE. There is no
1688 current work around to re-establish the 2.2 behavior.
1690 2) When adding machines to a Samba 2.2 controlled domain, the
1691 'add user script' was used to create the UNIX identity of the
1692 machine trust account. Samba 3.0 introduces a new 'add machine
1693 script' that must be specified for this purpose. Samba 3.0 will
1694 not fall back to using the 'add user script' in the absence of
1695 an 'add machine script'
1698 ######################################################################
1699 Passdb Backends and Authentication
1700 ##################################
1702 There have been a few new changes that Samba administrators should be
1703 aware of when moving to Samba 3.0.
1705 1) encrypted passwords have been enabled by default in order to
1706 inter-operate better with out-of-the-box Windows client
1707 installations. This does mean that either (a) a samba account
1708 must be created for each user, or (b) 'encrypt passwords = no'
1709 must be explicitly defined in smb.conf.
1711 2) Inclusion of new 'security = ads' option for integration
1712 with an Active Directory domain using the native Windows
1713 Kerberos 5 and LDAP protocols.
1715 MIT kerberos 1.3.1 supports the ARCFOUR-HMAC-MD5 encryption
1716 type which is neccessary for servers on which the
1717 administrator password has not been changed, or kerberos-enabled
1718 SMB connections to servers that require Kerberos SMB signing.
1719 Besides this one difference, either MIT or Heimdal Kerberos
1720 distributions are usable by Samba 3.0.
1723 Samba 3.0 also includes the possibility of setting up chains
1724 of authentication methods (auth methods) and account storage
1725 backends (passdb backend). Please refer to the smb.conf(5)
1726 man page for details. While both parameters assume sane default
1727 values, it is likely that you will need to understand what the
1728 values actually mean in order to ensure Samba operates correctly.
1730 The recommended passdb backends at this time are
1732 * smbpasswd - 2.2 compatible flat file format
1733 * tdbsam - attribute rich database intended as an smbpasswd
1734 replacement for stand alone servers
1735 * ldapsam - attribute rich account storage and retrieval
1736 backend utilizing an LDAP directory.
1737 * ldapsam_compat - a 2.2 backward compatible LDAP account
1740 Certain functions of the smbpasswd(8) tool have been split between the
1741 new smbpasswd(8) utility, the net(8) tool, and the new pdbedit(8)
1742 utility. See the respective man pages for details.
1745 ######################################################################
1749 This section outlines the new features affecting Samba / LDAP
1755 A new object class (sambaSamAccount) has been introduced to replace
1756 the old sambaAccount. This change aids us in the renaming of
1757 attributes to prevent clashes with attributes from other vendors.
1758 There is a conversion script (examples/LDAP/convertSambaAccount) to
1759 modify and LDIF file to the new schema.
1763 $ ldapsearch .... -b "ou=people,dc=..." > sambaAcct.ldif
1764 $ convertSambaAccount --sid=<Domain SID> \
1765 --input=sambaAcct.ldif --output=sambaSamAcct.ldif \
1766 --changetype=[modify|add]
1768 The <DOM SID> can be obtained by running 'net getlocalsid
1769 <DOMAINNAME>' on the Samba PDC as root. The changetype determines
1770 the format of the generated LDIF output--either create new entries
1771 or modify existing entries.
1773 The old sambaAccount schema may still be used by specifying the
1774 "ldapsam_compat" passdb backend. However, the sambaAccount and
1775 associated attributes have been moved to the historical section of
1776 the schema file and must be uncommented before use if needed.
1777 The 2.2 object class declaration for a sambaAccount has not changed
1778 in the 3.0 samba.schema file.
1780 Other new object classes and their uses include:
1782 * sambaDomain - domain information used to allocate rids
1783 for users and groups as necessary. The attributes are added
1784 in 'ldap suffix' directory entry automatically if
1785 an idmap uid/gid range has been set and the 'ldapsam'
1786 passdb backend has been selected.
1788 * sambaGroupMapping - an object representing the
1789 relationship between a posixGroup and a Windows
1790 group/SID. These entries are stored in the 'ldap
1791 group suffix' and managed by the 'net groupmap' command.
1793 * sambaUnixIdPool - created in the 'ldap idmap suffix' entry
1794 automatically and contains the next available 'idmap uid' and
1797 * sambaIdmapEntry - object storing a mapping between a
1798 SID and a UNIX uid/gid. These objects are created by the
1799 idmap_ldap module as needed.
1801 * sambaSidEntry - object representing a SID alone, as a Structural
1802 class on which to build the sambaIdmapEntry.
1805 New Suffix for Searching
1806 ------------------------
1808 The following new smb.conf parameters have been added to aid in directing
1809 certain LDAP queries when 'passdb backend = ldapsam://...' has been
1812 * ldap suffix - used to search for user and computer accounts
1813 * ldap user suffix - used to store user accounts
1814 * ldap machine suffix - used to store machine trust accounts
1815 * ldap group suffix - location of posixGroup/sambaGroupMapping entries
1816 * ldap idmap suffix - location of sambaIdmapEntry objects
1818 If an 'ldap suffix' is defined, it will be appended to all of the
1819 remaining sub-suffix parameters. In this case, the order of the suffix
1820 listings in smb.conf is important. Always place the 'ldap suffix' first
1823 Due to a limitation in Samba's smb.conf parsing, you should not surround
1824 the DN's with quotation marks.
1830 Samba 3.0 supports an ldap backend for the idmap subsystem. The
1831 following options would inform Samba that the idmap table should be
1832 stored on the directory server onterose in the "ou=idmap,dc=plainjoe,
1837 idmap backend = ldap:ldap://onterose/
1838 ldap idmap suffix = ou=idmap,dc=plainjoe,dc=org
1839 idmap uid = 40000-50000
1840 idmap gid = 40000-50000
1842 This configuration allows winbind installations on multiple servers to
1843 share a uid/gid number space, thus avoiding the interoperability problems
1844 with NFS that were present in Samba 2.2.
1848 ######################################################################
1849 Trust Relationships and a Samba Domain
1850 ######################################
1852 Samba 3.0.0beta2 is able to utilize winbindd as the means of
1853 allocating uids and gids to trusted users and groups. More
1854 information regarding Samba's support for establishing trust
1855 relationships can be found in the Samba-HOWTO-Collection included
1856 in the docs/ directory of this release.
1858 First create your Samba PDC and ensure that everything is
1859 working correctly before moving on the trusts.
1861 To establish Samba as the trusting domain (named SAMBA) from a Windows NT
1862 4.0 domain named WINDOWS:
1864 1) create the trust account for SAMBA in "User Manager for Domains"
1865 2) connect the trust from the Samba domain using
1866 'net rpc trustdom establish GLASS'
1868 To create a trustlationship with SAMBA as the trusted domain:
1870 1) create the initial trust account for GLASS using
1871 'smbpasswd -a -i GLASS'. You may need to create a UNIX
1872 account for GLASS$ prior to this step (depending on your
1873 local configuration).
1874 2) connect the trust from a WINDOWS DC using "User Manager
1877 Now join winbindd on the Samba PDC to the SAMBA domain using
1878 the normal steps for adding a Samba server to an NT4 domain:
1879 (note that smbd & nmbd must be running at this point)
1881 root# net rpc join -U root
1882 Password: <enter root password from smbpasswd file here>
1884 Start winbindd and test the join with 'wbinfo -t'.
1886 Now test the trust relationship by connecting to the SAMBA DC
1887 (e.g. POGO) as a user from the WINDOWS domain:
1889 $ smbclient //pogo/netlogon -U Administrator -W WINDOWS
1892 Now connect to the WINDOWS DC (e.g. CRYSTAL) as a Samba user:
1894 $ smbclient //crystal/netlogon -U root -W WINDOWS
1897 ######################################################################
1901 Beginning with Samba3.0.0beta3, winbindd has been given new account
1902 manage functionality equivalent to the 'add user script' family of
1903 smb.conf parameters. The idmap design has also been changed to
1904 centralize control of foreign SID lookups and matching to UNIX
1908 Brief Description of Changes
1909 ----------------------------
1911 1) The sid_to_uid() family of functions (smbd/uid.c) have been
1912 reverted to the 2.2.x design. This means that when resolving a
1913 SID to a UID or similar mapping:
1915 a) First consult winbindd
1916 b) perform a local lookup only if winbindd fails to
1917 return a successful answer
1919 There are some variations to this, but these two rules generally
1922 2) All idmap lookups have been moved into winbindd. This means that
1923 a server must run winbindd (and support NSS) in order to achieve
1924 any mappings of SID to dynamically allocated UNIX ids. This was
1925 a conscious design choice.
1927 3) New functions have been added to winbindd to emulate the 'add user
1928 script' family of smbd functions without requiring that external
1929 scripts be defined. This functionality is controlled by the 'winbind
1930 enable local accounts' smb.conf parameter (enabled by default).
1932 However, this account management functionality is only supported
1933 in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts
1934 must be shared among multiple Samba servers (such as a PDC and BDCs),
1935 it will be necessary to define your own 'add user script', et. al.
1936 programs that place the accounts/groups in some form of directory
1937 such as NIS or LDAP. This requirement was deemed beyond the scope
1938 of winbind's account management functions. Solutions for
1939 distributing UNIX system information have been deployed and tested
1940 for many years. We saw no need to reinvent the wheel.
1942 4) A member of a Samba controlled domain running winbindd is now able
1943 to map domain users directly onto existing UNIX accounts while still
1944 automatically creating accounts for trusted users and groups. This
1945 behavior is controlled by the 'winbind trusted domains only' smb.conf
1946 parameter (disabled by default to provide 2.2.x winbind behavior).
1948 5) Group mapping support is wrapped in the local_XX_to_XX() functions
1949 in smbd/uid.c. The reason that group mappings are not included
1950 in winbindd is because the purpose of Samba's group map is to
1951 match any Windows SID with an existing UNIX group. These UNIX
1952 groups can be created by winbindd (see next section), but the
1953 SID<->gid mapping is retreived by smbd, not winbindd.
1959 * security = server running winbindd to allocate accounts on demand
1961 * Samba PDC running winbindd to handle the automatic creation of UNIX
1962 identities for machine trust accounts
