409 =============================
410 Release Notes for Samba 4.8.7
411 November 27, 2018
412 =============================
415 This is a security release in order to address the following defects:
417 o CVE-2018-14629 (Unprivileged adding of CNAME record causing loop in AD
418 Internal DNS server)
419 o CVE-2018-16841 (Double-free in Samba AD DC KDC with PKINIT)
420 o CVE-2018-16851 (NULL pointer de-reference in Samba AD DC LDAP server)
421 o CVE-2018-16853 (Samba AD DC S4U2Self crash in experimental MIT Kerberos
422 configuration (unsupported))
425 =======
426 Details
427 =======
429 o CVE-2018-14629:
430 All versions of Samba from 4.0.0 onwards are vulnerable to infinite
431 query recursion caused by CNAME loops. Any dns record can be added via
432 ldap by an unprivileged user using the ldbadd tool, so this is a
433 security issue.
435 o CVE-2018-16841:
436 When configured to accept smart-card authentication, Samba's KDC will call
437 talloc_free() twice on the same memory if the principal in a validly signed
438 certificate does not match the principal in the AS-REQ.
440 This is only possible after authentication with a trusted certificate.
442 talloc is robust against further corruption from a double-free with
443 talloc_free() and directly calls abort(), terminating the KDC process.
445 There is no further vulnerability associated with this issue, merely a
446 denial of service.
448 o CVE-2018-16851:
449 During the processing of an LDAP search before Samba's AD DC returns
450 the LDAP entries to the client, the entries are cached in a single
451 memory object with a maximum size of 256MB. When this size is
452 reached, the Samba process providing the LDAP service will follow the
453 NULL pointer, terminating the process.
455 There is no further vulnerability associated with this issue, merely a
456 denial of service.
458 o CVE-2018-16853:
459 A user in a Samba AD domain can crash the KDC when Samba is built in the
460 non-default MIT Kerberos configuration.
462 With this advisory we clarify that the MIT Kerberos build of the Samba
463 AD DC is considered experimental. Therefore the Samba Team will not
464 issue security patches for this configuration.
466 For more details and workarounds, please refer to the security advisories.
469 Changes since 4.8.6:
470 --------------------
472 o Andrew Bartlett <abartlet@samba.org>
473 * BUG 13628: CVE-2018-16841: heimdal: Fix segfault on PKINIT with
474 mis-matching principal.
475 * BUG 13678: CVE-2018-16853: build: The Samba AD DC, when build with MIT
476 Kerberos is experimental
478 o Aaron Haslett <aaronhaslett@catalyst.net.nz>
479 * BUG 13600: CVE-2018-14629: dns: CNAME loop prevention using counter.
481 o Garming Sam <garming@catalyst.net.nz>
482 * BUG 13674: CVE-2018-16851: ldap_server: Check ret before manipulating blob.

1070 Release Notes for Samba 4.8.0
1071 March 13, 2018
1072 =============================
1075 This is the first stable release of the Samba 4.8 release series.
1076 Please read the release notes carefully before upgrading.
1079 UPGRADING
1080 =========
1082 New GUID Index mode in sam.ldb for the AD DC
1083 --------------------------------------------
1085 Users who upgrade a Samba AD DC in-place will experience a short delay
1086 in the first startup of Samba while the sam.ldb is re-indexed.
1088 Unlike in previous releases a transparent downgrade is not possible.
1089 If you wish to downgrade such a DB to a Samba 4.7 or earlier version,
1090 please run the source4/scripting/bin/sambaundoguididx script first.
1092 Domain member setups require winbindd
1093 -------------------------------------
1095 Setups with "security = domain" or "security = ads" require a
1096 running 'winbindd' now. The fallback that smbd directly contacts
1097 domain controllers is gone.
1099 smbclient reparse point symlink parameters reversed
1100 ---------------------------------------------------
1102 See the more detailed description below.
1104 Changed trusted domains listing with wbinfo -m --verbose
1105 --------------------------------------------------------
1107 See the more detailed description below.
1109 NEW FEATURES/CHANGES
1110 ====================
1112 New GUID Index mode in sam.ldb for the AD DC
1113 --------------------------------------------
1115 The new layout used for sam.ldb is GUID, rather than DN oriented.
1116 This provides Samba's Active Directory Domain Controller with a faster
1117 database, particularly at larger scale.
1119 The underlying DB is still TDB, simply the choice of key has changed.
1121 The new mode is not optional, so no configuration is required. Older
1122 Samba versions cannot read the new database (see the upgrade
1123 note above).
1125 KDC GPO application
1126 -------------------
1128 Adds Group Policy support for the Samba kdc. Applies password policies
1129 (minimum/maximum password age, minimum password length, and password
1130 complexity) and kerberos policies (user/service ticket lifetime and
1131 renew lifetime).
1133 Adds the samba_gpoupdate script for applying and unapplying
1134 policy. Can be applied automatically by setting
1136 'apply group policies = yes'.
1138 Time Machine Support with vfs_fruit
1139 -----------------------------------
1141 Samba can be configured as a Time Machine target for Apple Mac devices
1142 through the vfs_fruit module. When enabling a share for Time Machine
1143 support the relevant Avahi records to support discovery will be published
1144 for installations that have been built against the Avahi client library.
1146 Shares can be designated as a Time Machine share with the following setting:
1148 'fruit:time machine = yes'
1150 Support for lower casing the MDNS Name
1151 --------------------------------------
1153 Allows the server name that is advertised through MDNS to be set to the
1154 hostname rather than the Samba NETBIOS name. This allows an administrator
1155 to make Samba registered MDNS records match the case of the hostname
1156 rather than being in all capitals.
1158 This can be set with the following settings:
1160 'mdns name = mdns'
1162 Encrypted secrets
1163 -----------------
1165 Attributes deemed to be sensitive are now encrypted on disk. The sensitive
1166 values are currently:
1167 pekList
1168 msDS-ExecuteScriptPassword
1169 currentValue
1170 dBCSPwd
1171 initialAuthIncoming
1172 initialAuthOutgoing
1173 lmPwdHistory
1174 ntPwdHistory
1175 priorValue
1176 supplementalCredentials
1177 trustAuthIncoming
1178 trustAuthOutgoing
1179 unicodePwd
1180 clearTextPassword
1182 This encryption is enabled by default on a new provision or join, it
1183 can be disabled at provision or join time with the new option
1184 '--plaintext-secrets'.
1186 However, an in-place upgrade will not encrypt the database.
1188 Once encrypted, it is not possible to do an in-place downgrade (eg to
1189 4.7) of the database. To obtain an unencrypted copy of the database a
1190 new DC join should be performed, specifying the '--plaintext-secrets'
1191 option.
1193 The key file "encrypted_secrets.key" is created in the same directory
1194 as the database and should NEVER be disclosed. It is included by the
1195 samba_backup script.
1197 Active Directory replication visualisation
1198 ------------------------------------------
1200 To work out what is happening in a replication graph, it is sometimes
1201 helpful to use visualisations. We introduce a samba-tool subcommand to
1202 write Graphviz dot output and generate text-based heatmaps of the
1203 distance in hops between DCs.
1205 There are two subcommands, two graphical modes, and (roughly) two modes of
1206 operation with respect to the location of authority.
1208 `samba-tool visualize ntdsconn` looks at NTDS Connections.
1209 `samba-tool visualize reps` looks at repsTo and repsFrom objects.
1211 In '--distance' mode (default), the distances between DCs are shown in
1212 a matrix in the terminal. With '--color=yes', this is depicted as a
1213 heatmap. With '--utf8' it is a lttle prettier.
1215 In '--dot' mode, Graphviz dot output is generated. When viewed using
1216 dot or xdot, this shows the network as a graph with DCs as vertices
1217 and connections edges. Certain types of degenerate edges are shown in
1218 different colours or line-styles.
1220 smbclient reparse point symlink parameters reversed
1221 ---------------------------------------------------
1223 A bug in smbclient caused the 'symlink' command to reverse the
1224 meaning of the new name and link target parameters when creating a
1225 reparse point symlink against a Windows server. As this is a
1226 little used feature the ordering of these parameters has been
1227 reversed to match the parameter ordering of the UNIX extensions
1228 'symlink' command. The usage message for this command has also
1229 been improved to remove confusion.
1231 Winbind changes
1232 ---------------
1234 The dependency to global list of trusted domains within
1235 the winbindd processes has been reduced a lot.
1237 The construction of that global list is not reliable and often
1238 incomplete in complex trust setups. In most situations the list is not needed
1239 any more for winbindd to operate correctly. E.g. for plain file serving via SMB
1240 using a simple idmap setup with autorid, tdb or ad. However some more complex
1241 setups require the list, e.g. if you specify idmap backends for specific
1242 domains. Some pam_winbind setups may also require the global list.
1244 If you have a setup that doesn't require the global list, you should set
1245 "winbind scan trusted domains = no".
1247 Improved support for trusted domains (as AD DC)
1248 -----------------------------------------------
1250 The support for trusted domains/forests has improved a lot.
1252 External domain trusts, as well a transitive forest trusts,
1253 are supported in both directions (inbound and outbound)
1254 for Kerberos and NTLM authentication now.
1256 The LSA LookupNames and LookupSids implementations
1257 support resolving names and sids from trusts domains/forest
1258 now. This is important in order to allow Samba based
1259 domain members to make use of the trust.
1261 However there are currently still a few limitations:
1263 - It's not possible to add users/groups of a trusted domain
1264 into domain groups. So group memberships are not expanded
1265 on trust boundaries.
1266 See https://bugzilla.samba.org/show_bug.cgi?id=13300
1267 - Both sides of the trust need to fully trust each other!
1268 - No SID filtering rules are applied at all!
1269 - This means DCs of domain A can grant domain admin rights
1270 in domain B.
1271 - Selective (CROSS_ORIGANIZATION) authentication is
1272 not supported. It's possible to create such a trust,
1273 but the KDC and winbindd ignore them.
1275 Changed trusted domains listing with wbinfo -m --verbose
1276 --------------------------------------------------------
1278 The trust properties printed by wbinfo -m --verbose have been changed to
1279 correctly reflect the view of the system where wbinfo is executed.
1281 The trust type field in particular can show additional values that correctly
1282 reflect the type of the trust: "Local" for the local SAM and BUILTIN,
1283 "Workstation" for a workstation trust to the primary domain, "RWDC" for the SAM
1284 on a AD DC, "RODC" for the SAM on a read-only DC, "PDC" for the SAM on a
1285 NT4-style DC, "Forest" for a AD forest trust and "External" for quarantined,
1286 external or NT4-style trusts.
1288 Indirect trusts are shown as "Routed" including the routing domain.
1290 Example, on a AD DC (SDOM1):
1292 Domain Name DNS Domain Trust Type Transitive In Out
1293 BUILTIN Local
1294 SDOM1 sdom1.site RWDC
1295 WDOM3 wdom3.site Forest Yes No Yes
1296 WDOM2 wdom2.site Forest Yes Yes Yes
1297 SUBDOM31 subdom31.wdom3.site Routed (via WDOM3)
1298 SUBDOM21 subdom21.wdom2.site Routed (via WDOM2)
1300 Same setup, on a member of WDOM2:
1302 Domain Name DNS Domain Trust Type Transitive In Out
1303 BUILTIN Local
1304 TITAN Local
1305 WDOM2 wdom2.site Workstation Yes No Yes
1306 WDOM1 wdom1.site Routed (via WDOM2)
1307 WDOM3 wdom3.site Routed (via WDOM2)
1308 SUBDOM21 subdom21.wdom2.site Routed (via WDOM2)
1309 SDOM1 sdom1.site Routed (via WDOM2)
1310 SUBDOM11 subdom11.wdom1.site Routed (via WDOM2)
1312 The list of trusts may be incomplete and additional domains may appear as
1313 "Routed" if a user of an unknown domain is successfully authenticated.
1315 VirusFilter VFS module
1316 ----------------------
1318 This new module integrates with Sophos, F-Secure and ClamAV anti-virus
1319 software to provide scanning and filtering of files on a Samba share.
1322 Local authorization plugin for MIT Kerberos
1323 -------------------------------------------
1325 This plugin controls the relationship between Kerberos principals and AD
1326 accounts through winbind. The module receives the Kerberos principal and the
1327 local account name as inputs and can then check if they match. This can resolve
1328 issues with canonicalized names returned by Kerberos within AD. If the user
1329 tries to log in as 'alice', but the samAccountName is set to ALICE (uppercase),
1330 Kerberos would return ALICE as the username. Kerberos would not be able to map
1331 'alice' to 'ALICE' in this case and auth would fail. With this plugin account
1332 names can be correctly mapped. This only applies to GSSAPI authentication,
1333 not for the geting the initial ticket granting ticket.
1335 New glusterfs_fuse VFS module
1336 -----------------------------
1338 The new vfs_glusterfs_fuse module improves performance when Samba
1339 accesses a glusterfs volume mounted via FUSE (Filesystem in Userspace
1340 as part of the Linux kernel). It achieves that by leveraging a
1341 mechanism to retrieve the appropriate case of filenames by querying a
1342 specific extended attribute in the filesystem. No extra configuration
1343 is required to use this module, only glusterfs_fuse needs to be set in
1344 the "vfs objects" parameter. Further details can be found in the
1345 vfs_glusterfs_fuse(8) manpage. This new vfs_glusterfs_fuse module does
1346 not replace the existing vfs_glusterfs module, it just provides an
1347 additional, alternative mechanism to access a Gluster volume.
1349 REMOVED FEATURES
1350 ================
1352 'net serverid' commands removed
1353 -------------------------------
1355 The two commands 'net serverid list' and 'net serverid wipe' have been
1356 removed, because the file serverid.tdb is not used anymore.
1358 'net serverid list' can be replaced by listing all files in the
1359 subdirectory "msg.lock" of Samba's "lock directory". The unique id
1360 listed by 'net serverid list' is stored in every process' lockfile in
1361 "msg.lock".
1363 'net serverid wipe' is not necessary anymore. It was meant primarily
1364 for clustered environments, where the serverid.tdb file was not
1365 properly cleaned up after single node crashes. Nowadays smbd and
1366 winbind take care of cleaning up the msg.lock and msg.sock directories
1367 automatically.
1369 NT4-style replication based net commands removed
1370 ------------------------------------------------
1372 The following commands and sub-commands have been removed from the
1373 "net" utility:
1375 net rpc samdump
1376 net rpc vampire ldif
1378 Also, replicating from a real NT4 domain with "net rpc vampire" and
1379 "net rpc vampire keytab" has been removed.
1381 The NT4-based commands were accidentally broken in 2013, and nobody
1382 noticed the breakage. So instead of fixing them including tests (which
1383 would have meant writing a server for the protocols, which we don't
1384 have) we decided to remove them.
1386 For the same reason, the "samsync", "samdeltas" and "database_redo"
1387 commands have been removed from rpcclient.
1389 "net rpc vampire keytab" from Active Directory domains continues to be
1390 supported.
1392 vfs_aio_linux module removed
1393 ----------------------------
1395 The current Linux kernel aio does not match what Samba would
1396 do. Shipping code that uses it leads people to false
1397 assumptions. Samba implements async I/O based on threads by default,
1398 there is no special module required to see benefits of read and write
1399 request being sent do the disk in parallel.
1402 smb.conf changes
1403 ================
1405 Parameter Name Description Default
1406 -------------- ----------- -------
