Release Notes for Samba 4.9.3
November 27, 2018
=============================
This is a security release in order to address the following defects:
o CVE-2018-14629 (Unprivileged adding of CNAME record causing loop in AD
Internal DNS server)
o CVE-2018-16841 (Double-free in Samba AD DC KDC with PKINIT)
o CVE-2018-16851 (NULL pointer de-reference in Samba AD DC LDAP server)
o CVE-2018-16852 (NULL pointer de-reference in Samba AD DC DNS servers)
o CVE-2018-16853 (Samba AD DC S4U2Self crash in experimental MIT Kerberos
configuration (unsupported))
o CVE-2018-16857 (Bad password count in AD DC not always effective)
=======
Details
=======
o CVE-2018-14629:
All versions of Samba from 4.0.0 onwards are vulnerable to infinite
query recursion caused by CNAME loops. Any dns record can be added via
ldap by an unprivileged user using the ldbadd tool, so this is a
security issue.
o CVE-2018-16841:
When configured to accept smart-card authentication, Samba\'s KDC will call
talloc_free() twice on the same memory if the principal in a validly signed
certificate does not match the principal in the AS-REQ.
This is only possible after authentication with a trusted certificate.
talloc is robust against further corruption from a double-free with
talloc_free() and directly calls abort(), terminating the KDC process.
There is no further vulnerability associated with this issue, merely a
denial of service.
o CVE-2018-16851:
During the processing of an LDAP search before Samba\'s AD DC returns
the LDAP entries to the client, the entries are cached in a single
memory object with a maximum size of 256MB. When this size is
reached, the Samba process providing the LDAP service will follow the
NULL pointer, terminating the process.
There is no further vulnerability associated with this issue, merely a
denial of service.
o CVE-2018-16852:
During the processing of an DNS zone in the DNS management DCE/RPC server,
the internal DNS server or the Samba DLZ plugin for BIND9, if the
DSPROPERTY_ZONE_MASTER_SERVERS property or DSPROPERTY_ZONE_SCAVENGING_SERVERS
property is set, the server will follow a NULL pointer and terminate.
There is no further vulnerability associated with this issue, merely a
denial of service.
o CVE-2018-16853:
A user in a Samba AD domain can crash the KDC when Samba is built in the
non-default MIT Kerberos configuration.
With this advisory we clarify that the MIT Kerberos build of the Samba
AD DC is considered experimental. Therefore the Samba Team will not
issue security patches for this configuration.
o CVE-2018-16857:
AD DC Configurations watching for bad passwords (to restrict brute forcing
of passwords) in a window of more than 3 minutes may not watch for bad
passwords at all.
For more details and workarounds, please refer to the security advisories.
Changes since 4.9.2:
o Andrew Bartlett
* BUG 13628: CVE-2018-16841: heimdal: Fix segfault on PKINIT with
mis-matching principal.
* BUG 13678: CVE-2018-16853: build: The Samba AD DC, when build with MIT
Kerberos is experimental
o Tim Beale
* BUG 13683: CVE-2018-16857: dsdb/util: Correctly treat
lockOutObservationWindow as 64-bit int.
o Joe Guo
* BUG 13683: CVE-2018-16857 PEP8: Fix E305: Expected 2 blank lines after
class or function definition, found 1.
o Aaron Haslett
* BUG 13600: CVE-2018-14629: dns: CNAME loop prevention using counter.
o Gary Lockyer
* BUG 13669: CVE-2018-16852: Fix NULL pointer de-reference in Samba AD DC
DNS management.
o Garming Sam
* BUG 13674: CVE-2018-16851: ldap_server: Check ret before manipulating blob.

Major enhancements include:
o BUG 13228: This is a major issue in Samba\'s ActiveDirectory domain
controller code. It might happen that AD objects have missing or broken
linked attributes. This could lead to broken group memberships e.g.
All Samba AD domain controllers set up with Samba 4.6 or lower and then
upgraded to 4.7 are affected. The corrupt database can be fixed with
\'samba-tool dbcheck --cross-ncs --fix\'.

smbclient reparse point symlink parameters reversed
A bug in smbclient caused the \'symlink\' command to reverse the
meaning of the new name and link target parameters when creating a
reparse point symlink against a Windows server.
This only affects using the smbclient \'symlink\' command against
a Windows server, not a Samba server using the UNIX extensions
(the parameter order is correct in that case) so no existing
user scripts that depend on creating symlinks on Samba servers
need to change.
As this is a little used feature the ordering of these parameters
has been reversed to match the parameter ordering of the UNIX
extensions \'symlink\' command. This means running \'symlink\' against
both Windows and Samba now uses the same paramter ordering in both
cases.
The usage message for this command has also been improved to remove confusion.

This is a security release in order to address the following defects:
o CVE-2017-14746 (Use-after-free vulnerability.)
o CVE-2017-15275 (Server heap memory information leak.)
=======
Details
=======
o CVE-2017-14746:
All versions of Samba from 4.0.0 onwards are vulnerable to a use after
free vulnerability, where a malicious SMB1 request can be used to
control the contents of heap memory via a deallocated heap pointer. It
is possible this may be used to compromise the SMB server.
o CVE-2017-15275:
All versions of Samba from 3.6.0 onwards are vulnerable to a heap
memory information leak, where server allocated heap memory may be
returned to the client without being cleared.
There is no known vulnerability associated with this error, but
uncleared heap memory may contain previously used data that may help
an attacker compromise the server via other methods. Uncleared heap
memory may potentially contain password hashes or other high-value
data.

- \'smbclient\' changes
\'smbclient\' no longer prints a \'Domain=[...] OS=[Windows 6.1] Server=[...]\'
banner when connecting to the first server. With SMB2 and Kerberos,
there\'s no way to print this information reliably. Now we avoid it at all
consistently. In interactive sessions the following banner is now presented
to the user: \'Try \"help\" do get a list of possible commands.\'.
The default for \"client max protocol\" has changed to \"SMB3_11\",
which means that \'smbclient\' (and related commands) will work against
servers without SMB1 support.
It\'s possible to use the \'-m/--max-protocol\' option to overwrite
the \"client max protocol\" option temporarily.
Note that the \'-e/--encrypt\' option also works with most SMB3 servers
(e.g. Windows >= 2012 and Samba >= 4.0.0), so the SMB1 unix extensions
are not required for encryption.
The change to SMB3_11 as default also means \'smbclient\' no longer
negotiates SMB1 unix extensions by default, when talking to a Samba server with
\"unix extensions = yes\". As a result, some commands are not available, e.g.
\'posix_encrypt\', \'posix_open\', \'posix_mkdir\', \'posix_rmdir\', \'posix_unlink\',
\'posix_whoami\', \'getfacl\' and \'symlink\'. Using \"-mNT1\" reenables them, if the
server supports SMB1.
Note the default (\"CORE\") for \"client min protocol\" hasn\'t changed,
so it\'s still possible to connect to SMB1-only servers by default.
\'smbclient\' learned a new command \'deltree\' that is able to do
a recursive deletion of a directory tree.
NEW FEATURES/CHANGES
====================
Whole DB read locks: Improved LDAP and replication consistency
Prior to Samba 4.7 and ldb 1.2.0, the LDB database layer used by Samba
erroneously did not take whole-DB read locks to protect search
and DRS replication operations.
While each object returned remained subject to a record-level lock (so
would remain consistent to itself), under a race condition with a
rename or delete, it and any links (like the member attribute) to it
would not be returned.
The symptoms of this issue include:
Replication failures with this error showing in the client side logs:
error during DRS repl ADD: No objectClass found in replPropertyMetaData for
Failed to commit objects:
WERR_GEN_FAILURE/NT_STATUS_INVALID_NETWORK_RESPONSE
A crash of the server, in particular the rpc_server process with
INTERNAL ERROR: Signal 11
LDAP read inconsistency
A DN subject to a search at the same time as it is being renamed
may not appear under either the old or new name, but will re-appear
for a subsequent search.
See https://bugzilla.samba.org/show_bug.cgi?id=12858 for more details
and updated advise on database recovery for affected installations.
Samba AD with MIT Kerberos
After four years of development, Samba finally supports compiling and
running Samba AD with MIT Kerberos. You can enable it with:
./configure --with-system-mitkrb5
Samba requires version 1.15.1 of MIT Kerberos to build with AD DC support.
The krb5-devel and krb5-server packages are required.
The feature set is not on par with the Heimdal build but the most important
things, like forest and external trusts, are working. Samba uses the KDC binary
provided by MIT Kerberos.
Missing features, compared to Heimdal, are:
* PKINIT support
* S4U2SELF/S4U2PROXY support
* RODC support (not fully working with Heimdal either)
The Samba AD process will take care of starting the MIT KDC and it will load a
KDB (Kerberos Database) driver to access the Samba AD database. When
provisioning an AD DC using \'samba-tool\' it will take care of creating a correct
kdc.conf file for the MIT KDC.
For further details, see:
https://wiki.samba.org/index.php/Running_a_Samba_AD_DC_with_MIT_Kerberos_KDC
Dynamic RPC port range
The dynamic port range for RPC services has been changed from the old default
value \"1024-1300\" to \"49152-65535\". This port range is not only used by a
Samba AD DC, but also applies to all other server roles including NT4-style
domain controllers. The new value has been defined by Microsoft in Windows
Server 2008 and newer versions. To make it easier for Administrators to control
those port ranges we use the same default and make it configurable with the
option: \"rpc server dynamic port range\".
The \"rpc server port\" option sets the first available port from the new
\"rpc server dynamic port range\" option. The option \"rpc server port\" only
applies to Samba provisioned as an AD DC.
Authentication and Authorization audit support
Detailed authentication and authorization audit information is now
logged to Samba\'s debug logs under the \"auth_audit\" debug class,
including in particular the client IP address triggering the audit
line. Additionally, if Samba is compiled against the jansson JSON
library, a JSON representation is logged under the \"auth_json_audit\"
debug class.
Audit support is comprehensive for all authentication and
authorisation of user accounts in the Samba Active Directory Domain
Controller, as well as the implicit authentication in password
changes. In the file server and classic/NT4 domain controller, NTLM
authentication, SMB and RPC authorization is covered, however password
changes are not at this stage, and this support is not currently
backed by a testsuite.
For further details, see:
https://wiki.samba.org/index.php/Setting_up_Audit_Logging
Multi-process LDAP Server
The LDAP server in the AD DC now honours the process model used for
the rest of the \'samba\' process, rather than being forced into a single
process. This aids in Samba\'s ability to scale to larger numbers of AD
clients and the AD DC\'s overall resiliency, but will mean that there is a
fork()ed child for every LDAP client, which may be more resource
intensive in some situations. If you run Samba in a
resource-constrained VM, consider allocating more RAM and swap space.
Improved Read-Only Domain Controller (RODC) Support
Support for RODCs in Samba AD until now has been experimental. With this latest
version, many of the critical bugs have been fixed and the RODC can be used in
DC environments requiring no writable behaviour. RODCs now correctly support
bad password lockouts and password disclosure auditing through the
msDS-RevealedUsers attribute.
The fixes made to the RWDC will also allow Windows RODC to function more
correctly and to avoid strange data omissions such as failures to replicate
groups or updated passwords. Password changes are currently rejected at the
RODC, although referrals should be given over LDAP. While any bad passwords can
trigger domain-wide lockout, good passwords which have not been replicated yet
for a password change can only be used via NTLM on the RODC (and not Kerberos).
The reliability of RODCs locating a writable partner still requires some
improvements and so the \'password server\' configuration option is generally
recommended on the RODC.
Samba 4.7 is the first Samba release to be secure as an RODC or when
hosting an RODC. If you have been using earlier Samba versions to
host or be an RODC, please upgrade.
In particular see https://bugzilla.samba.org/show_bug.cgi?id=12977 for
details on the security implications for password disclosure to an
RODC using earlier versions.
Additional password hashes stored in supplementalCredentials
A new config option \'password hash userPassword schemes\' has been added to
enable generation of SHA-256 and SHA-512 hashes (without storing the plaintext
password with reversible encryption). This builds upon previous work to improve
password sync for the AD DC (originally using GPG).
The user command of \'samba-tool\' has been updated in order to be able to
extract these additional hashes, as well as extracting the (HTTP) WDigest
hashes that we had also been storing in supplementalCredentials.
Improvements to DNS during Active Directory domain join
The \'samba-tool\' domain join command will now add the A and GUID DNS records
(on both the local and remote servers) during a join if possible via RPC. This
should allow replication to proceed more smoothly post-join.
The mname element of the SOA record will now also be dynamically generated to
point to the local read-write server. \'samba_dnsupdate\' should now be more
reliable as it will now find the appropriate name server even when resolv.conf
points to a forwarder.
Significant AD performance and replication improvements
Previously, replication of group memberships was been an incredibly expensive
process for the AD DC. This was mostly due to unnecessary CPU time being spent
parsing member linked attributes. The database now stores these linked
attributes in sorted form to perform efficient searches for existing members.
In domains with a large number of group memberships, a join can now be
completed in half the time compared with Samba 4.6.
LDAP search performance has also improved, particularly in the unindexed search
case. Parsing and processing of security descriptors should now be more
efficient, improving replication but also overall performance.
Query record for open file or directory
The record attached to an open file or directory in Samba can be
queried through the \'net tdb locking\' command. In clustered Samba this
can be useful to determine the file or directory triggering
corresponding \"hot\" record warnings in ctdb.
Removal of lpcfg_register_defaults_hook()
The undocumented and unsupported function lpcfg_register_defaults_hook()
that was used by external projects to call into Samba and modify
smb.conf default parameter settings has been removed. If your project
was using this call please raise the issue on
samba-technicalAATTlists.samba.org in order to design a supported
way of obtaining the same functionality.
Change of loadable module interface
The _init function of all loadable modules in Samba has changed
from:
NTSTATUS _init(void);
to:
NTSTATUS _init(TALLOC_CTX
*);
This allows a program loading a module to pass in a long-lived
talloc context (which must be guaranteed to be alive for the
lifetime of the module). This allows modules to avoid use of
the talloc_autofree_context() (which is inherently thread-unsafe)
and still be valgrind-clean on exit. Modules that don\'t need to
free long-lived data on exit should use the NULL talloc context.
SHA256 LDAPS Certificates
The self-signed certificate generated for use on LDAPS will now be
generated with a SHA256 self-signature, not a SHA1 self-signature.
Replacing this certificate with a certificate signed by a trusted
CA is still highly recommended.
CTDB changes
------------
* CTDB no longer allows mixed minor versions in a cluster
See the AllowMixedVersions tunable option in ctdb-tunables(7) and also
https://wiki.samba.org/index.php/Upgrading_a_CTDB_cluster#Policy
* CTDB now ignores hints from Samba about TDB flags when attaching to databases
CTDB will use the correct flags depending on the type of database.
For clustered databases, the smb.conf setting
dbwrap_tdb_mutexes:
*=true will be ignored. Instead, CTDB continues
to use the TDBMutexEnabled tunable.
* New configuration variable CTDB_NFS_CHECKS_DIR
See ctdbd.conf(5) for more details.
* The CTDB_SERVICE_AUTOSTARTSTOP configuration variable has been
removed
To continue to manage/unmanage services while CTDB is running:
- Start service by hand and then flag it as managed
- Mark service as unmanaged and shut it down by hand
- In some cases CTDB does something fancy - e.g. start Samba under
\"nice\", so care is needed. One technique is to disable the
eventscript, mark as managed, run the startup event by hand and then
re-enable the eventscript.
* The CTDB_SCRIPT_DEBUGLEVEL configuration variable has been removed
* The example NFS Ganesha call-out has been improved
* A new \"replicated\" database type is available
Replicated databases are intended for CTDB\'s internal use to
replicate state data across the cluster, but may find other
uses. The data in replicated databases is valid for the lifetime of
CTDB and cleared on first attach.
Using x86_64 Accelerated AES Crypto Instructions
Samba on x86_64 can now be configured to use the Intel accelerated AES
instruction set, which has the potential to make SMB3 signing and
encryption much faster on client and server. To enable this, configure
Samba using the new option --accel-aes=intelaesni.
This is a temporary solution that is being included to allow users
to enjoy the benefits of Intel accelerated AES on the x86_64 platform,
but the longer-term solution will be to move Samba to a fully supported
external crypto library.
The third_party/aesni-intel code will be removed from Samba as soon as
external crypto library performance reaches parity.
The default is to build without setting --accel-aes, which uses the
existing Samba software AES implementation.
Parameter changes
The \"strict sync\" global parameter has been changed from
a default of \"no\" to \"yes\". This means smbd will by default
obey client requests to synchronize unwritten data in operating
system buffers safely onto disk. This is a safer default setting
for modern SMB1/2/3 clients.
The \'ntlm auth\' option default is renamed to \'ntlmv2-only\', reflecting
the previous behaviour. Two new values have been provided,
\'mschapv2-and-ntlmv2-only\' (allowing MSCHAPv2 while denying NTLMv1)
and \'disabled\', totally disabling NTLM authentication and password
changes.
