243 Release Notes for Samba 4.0.8
244 August 05, 2013
245 =============================
248 This is a security release in order to address
249 CVE-2013-4124 (Missing integer wrap protection in EA list reading can cause
250 server to loop with DOS).
252 o CVE-2013-4124:
253 All current released versions of Samba are vulnerable to a denial of
254 service on an authenticated or guest connection. A malformed packet
255 can cause the smbd server to loop the CPU performing memory
256 allocations and preventing any further service.
258 A connection to a file share, or a local account is needed to exploit
259 this problem, either authenticated or unauthenticated if guest
260 connections are allowed.
262 This flaw is not exploitable beyond causing the code to loop
263 allocating memory, which may cause the machine to exceed memory
264 limits.
267 Changes since 4.0.7:
268 --------------------
270 o Jeremy Allison <jra@samba.org>
271 * BUG 10010: CVE-2013-4124: Missing integer wrap protection in EA list
272 reading can cause server to loop with DOS.

642 Note about upgrading from older versions:
643 -----------------------------------------
645 It is still the case that there are printing tdbs (ntprinting.tdb, ntforms.tdb,
646 ntdrivers.tdb) which are in latin1 or other encodings. When updating from
647 Samba 3.5 or earlier to Samba 3.6 or 4.0 these tdbs need to be migrated to our
648 new registry based printing management. This means during the migration we
649 also need to do charset conversion. This can only been done manually cause we don't
650 know in which encoding the tdb is. You have to specify the correct code page
651 for the conversion, see iconv -l and Wikipedia [1] for the available codepages.
652 The mostly used one is Windows Latin1 which is CP1252.
654 We've extended the 'net printing dump' and 'net printing migrate' commands to
655 define the encoding of the tdb. So you can correctly view the tdb with:
657 net printing dump encoding=CP1252 /path/to/ntprinters.tdb
659 or migrate it with e.g.:
661 net printing migrate encoding=CP1252 /path/to/ntprinters.tdb
663 If you migrate printers we suggest you do it in the following order.
665 ntforms.tdb
666 ntdrivers.tdb
667 ntprinting.tdb
669 Don't forget to rename, move or delete these files in /var/lib/samba after the
670 migration.

925 Release Notes for Samba 4.0.2
926 January 30, 2013
927 =============================
930 This is a security release in order to address
931 CVE-2013-0213 (Clickjacking issue in SWAT) and
932 CVE-2013-0214 (Potential XSRF in SWAT).
934 o CVE-2013-0213:
935 All current released versions of Samba are vulnerable to clickjacking in the
936 Samba Web Administration Tool (SWAT). When the SWAT pages are integrated into
937 a malicious web page via a frame or iframe and then overlaid by other content,
938 an attacker could trick an administrator to potentially change Samba settings.
940 In order to be vulnerable, SWAT must have been installed and enabled
941 either as a standalone server launched from inetd or xinetd, or as a
942 CGI plugin to Apache. If SWAT has not been installed or enabled (which
943 is the default install state for Samba) this advisory can be ignored.
945 o CVE-2013-0214:
946 All current released versions of Samba are vulnerable to a cross-site
947 request forgery in the Samba Web Administration Tool (SWAT). By guessing a
948 user's password and then tricking a user who is authenticated with SWAT into
949 clicking a manipulated URL on a different web page, it is possible to manipulate
950 SWAT.
952 In order to be vulnerable, the attacker needs to know the victim's password.
953 Additionally SWAT must have been installed and enabled either as a standalone
954 server launched from inetd or xinetd, or as a CGI plugin to Apache. If SWAT has
955 not been installed or enabled (which is the default install state for Samba)
956 this advisory can be ignored.

991 Release Notes for Samba 4.0.1
992 January 15, 2013
993 =============================
996 This is a security release in order to address CVE-2013-0172.
998 o CVE-2013-0172:
999 Samba 4.0.0 as an AD DC may provide authenticated users with write access
1000 to LDAP directory objects.
1002 In AD, Access Control Entries can be assigned based on the objectClass
1003 of the object. If a user or a group the user is a member of has any
1004 access based on the objectClass, then that user has write access to that
1005 object.
1007 Additionally, if a user has write access to any attribute on the object,
1008 they may have access to write to all attributes.
1010 An important mitigation is that anonymous access is totally disabled by
1011 default. The second important mitigation is that normal users are
1012 typically only given the problematic per-objectClass right via the
1013 "pre-windows 2000 compatible access" group, and Samba 4.0.0 incorrectly
1014 does not make "authenticated users" part of this group.
1016 Changes since 4.0.0:
1017 ====================
1019 o Andrew Bartlett <abartlet@samba.org>
1020 * Bug 9554 - CVE-2013-0172 - Samba 4.0 as an AD DC may provide authenticated
1021 users with write access to LDAP directory objects.

1047 Release Notes for Samba 4.0.0
1048 December 11, 2012
1049 =============================
1052 This is is the first stable release of Samba 4.0.
1054 This release contains the best of all of Samba's
1055 technology parts, both a file server (that you can reasonably expect
1056 to upgrade existing Samba 3.x releases to) and the AD domain
1057 controller work previously known as 'Samba4'.
1059 Major enhancements in Samba 4.0.0 include:
1061 Active Directory services
1062 =========================
1064 Samba 4.0 supports the server-side of the Active Directory logon
1065 environment used by Windows 2000 and later, so we can do full domain
1066 join and domain logon operations with these clients.
1068 Our Domain Controller (DC) implementation includes our own built-in
1069 LDAP server and Kerberos Key Distribution Center (KDC) as well as the
1070 Samba3-like logon services provided over CIFS. We correctly generate
1071 the infamous Kerberos PAC, and include it with the Kerberos tickets we
1072 issue.
1074 When running an AD DC, you only need to run 'samba' (not smbd/nmbd/winbindd),
1075 as the required services are co-coordinated by this master binary.
1076 The tool to administer the Active Directory services is called 'samba-tool'.
1078 A short guide to setting up Samba 4 as an AD DC can be found on the wiki:
1080 http://wiki.samba.org/index.php/Samba4/HOWTO
1083 File Services
1084 =============
1086 Samba 4.0.0 ships with two distinct file servers. We now use the
1087 file server from the Samba 3.x series 'smbd' for all file serving by
1088 default.
1090 Samba 4.0 also ships with the 'NTVFS' file server. This file server
1091 is what was used prior to the beta2 release of Samba 4.0, and is
1092 tuned to match the requirements of an AD domain controller. We
1093 continue to support this, not only to provide continuity to
1094 installations that have deployed it as part of an AD DC, but also as a
1095 running example of the NT-FSA architecture we expect to move smbd to in
1096 the longer term.
1098 For pure file server work, the binaries users would expect from that
1099 series (smbd, nmbd, winbindd, smbpasswd) continue to be available.
1102 Domain Member Support
1103 =====================
1105 Domain member support in the 'samba' binary is in its infancy, and
1106 is not comparable to the support found in 'winbindd'. As such, on
1107 Samba domain member servers, the binaries 'smbd', 'nmbd' and 'winbindd'
1108 are to be used, as known from Samba 3 domain member server setups.
1109 The only exceptions from this rule are the cases which explicitly
1110 require the 'samba' binary, namely running the ntvfs file server,
1111 the CIFS proxy or OpenChange on a domain member.
1114 DNS
1115 ===
1117 As DNS is an integral part of Active Directory, we also provide two DNS
1118 solutions, a simple internal DNS server for 'out of the box' configurations
1119 and a more elaborate BIND plugin using the BIND DLZ mechanism in versions
1120 9.8 and 9.9. During the provision, you can select which backend to use.
1121 With the internal backend, your DNS server is good to go.
1122 If you chose the BIND_DLZ backend, a configuration file will be generated
1123 for bind to make it use this plugin, as well as a file explaining how to
1124 set up bind.
1127 NTP
1128 ===
1130 To provide accurate timestamps to Windows clients, we integrate with
1131 the NTP project to provide secured NTP replies. To use you need to
1132 start ntpd and configure it with the 'restrict ... ms-sntp' and
1133 ntpsigndsocket options.
1136 Python Scripting Interface
1137 ==========================
1139 A new scripting interface has been added to Samba 4, allowing
1140 Python programs to interface to Samba's internals, and many tools and
1141 internal workings of the DC code is now implemented in python.
1144 Known Issues
1145 ============
1147 - Replication of DNS data from one AD server to another may not work.
1148 The DNS data used by the internal DNS server and bind9_dlz is stored
1149 in an application partition in our directory. The replication of
1150 this partition is not yet reliable.
1152 - Replication may fail on FreeBSD due to getaddrinfo() rejecting names
1153 containing _. A workaround will be in a future release.
1155 - samba_upgradeprovision should not be run when upgrading to this release
1156 from a recent release. No important database format changes have
1157 been made since alpha16.
1159 - Installation on systems without a system iconv (and developer
1160 headers at compile time) is known to cause errors when dealing with
1161 non-ASCII characters.
1163 - There is no NetBIOS browsing support (network neighbourhood)
1164 available for the AD domain controller. (Support in nmbd and smbd
1165 for classic domains and member/standalone servers is unchanged).
1167 - Clock Synchronisation is critical. Many 'wrong password' errors are
1168 actually due to Kerberos objecting to a clock skew between client
1169 and server. (The NTP work in the previous alphas are partly to assist
1170 with this problem).
1172 - The DRS replication code may fail. Please contact the team if you
1173 experience issues with DRS replication, as we have fixed many issues
1174 here in response to feedback from our production users.
1176 - Linux inotify will now only be supported on systems where glibc also supports
1177 it (for details, please refer to bug #8850).
1180 Upgrading
1181 =========
1183 Users upgrading from Samba 3.x domain controllers and wanting to use
1184 Samba 4.0 as an AD DC should use the 'samba-tool domain
1185 classicupgrade' command. See the wiki for more details:
1186 https://wiki.samba.org/index.php/Samba4/samba3upgrade/HOWTO.
1188 Users upgrading from Samba 4.0 alpha and beta releases since alpha15
1189 should run 'samba-tool dbcheck --cross-ncs --fix' before re-starting
1190 Samba. Users upgrading from earlier alpha releases should contact the
1191 team for advice.
1193 Users upgrading an AD DC from any previous release should run
1194 'samba-tool ntacl sysvolreset' to re-sync ACLs on the sysvol share
1195 with those matching the GPOs in LDAP and the defaults from an initial
1196 provision. This will set an underlying POSIX ACL if required (eg not
1197 using the NTVFS file server).
1199 If you used the BIND9_FLATFILE or BIND9_DLZ features,
1200 you'll have to add '-dns' to the 'server services' option,
1201 as the internal dns server (SAMBA_INTERNAL) is the default now.
1204 Supported features
1205 ==================

1327 CHANGES SINCE 4.0.0rc5
1328 ======================
1330 In this release candidate, we have a significant number of improvements
1331 to our Access Control List (ACL) code, particularly for the Active
1332 Directory Domain Controller, but also in our general purpose file
1333 server.
1335 These changes are important, as they enable Group Policy Objects to work
1336 correctly, allow administrators to impose restrictions on some users
1337 reading certain parts of the directory and correctly propagating
1338 inherited ACLs down the LDAP directory tree.
1340 Users of the Active Directory Domain Controller upgrading from any
1341 previous release should run 'samba-tool ntacl sysvolreset' to re-sync
1342 ACLs on the sysvol share with those matching the GPOs in LDAP and the
1343 defaults from an initial provision. This will set an underlying POSIX
1344 ACL if required.
1346 The ACLs in the Active Directory are also checked on searches by default.
1347 The automatic inheritance of ACLs is also correctly recalculated on
1348 changes now.

1359 ACLs backend.
