Release Notes for Samba 4.19.3
|
||
November 27, 2023
|
||
==============================
|
||
|
||
|
||
This is the latest stable release of the Samba 4.19 release series.
|
||
It contains the security-relevant bugfix CVE-2018-14628:
|
||
|
||
Wrong ntSecurityDescriptor values for "CN=Deleted Objects"
|
||
allow read of object tombstones over LDAP
|
||
(Administrator action required!)
|
||
https://www.samba.org/samba/security/CVE-2018-14628.html
|
||
|
||
|
||
Description of CVE-2018-14628
|
||
-----------------------------
|
||
|
||
All versions of Samba from 4.0.0 onwards are vulnerable to an
|
||
information leak (compared with the established behaviour of
|
||
Microsoft's Active Directory) when Samba is an Active Directory Domain
|
||
Controller.
|
||
|
||
When a domain was provisioned with an unpatched Samba version,
|
||
the ntSecurityDescriptor is simply inherited from Domain/Partition-HEAD-Object
|
||
instead of being very strict (as on a Windows provisioned domain).
|
||
|
||
This means also non privileged users can use the
|
||
LDAP_SERVER_SHOW_DELETED_OID control in order to view,
|
||
the names and preserved attributes of deleted objects.
|
||
|
||
No information that was hidden before the deletion is visible, but in
|
||
with the correct ntSecurityDescriptor value in place the whole object
|
||
is also not visible without administrative rights.
|
||
|
||
There is no further vulnerability associated with this error, merely an
|
||
information disclosure.
|
||
|
||
Action required in order to resolve CVE-2018-14628!
|
||
---------------------------------------------------
|
||
|
||
The patched Samba does NOT protect existing domains!
|
||
|
||
The administrator needs to run the following command
|
||
(on only one domain controller)
|
||
in order to apply the protection to an existing domain:
|
||
|
||
samba-tool dbcheck --cross-ncs --attrs=nTSecurityDescriptor --fix
|
||
|
||
The above requires manual interaction in order to review the
|
||
changes before they are applied. Typicall question look like this:
|
||
|
||
Reset nTSecurityDescriptor on CN=Deleted Objects,DC=samba,DC=org back to provision default?
|
||
Owner mismatch: SY (in ref) DA(in current)
|
||
Group mismatch: SY (in ref) DA(in current)
|
||
Part dacl is different between reference and current here is the detail:
|
||
(A;;LCRPLORC;;;AU) ACE is not present in the reference
|
||
(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;SY) ACE is not present in the reference
|
||
(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;DA) ACE is not present in the reference
|
||
(A;;CCDCLCSWRPWPSDRCWDWO;;;SY) ACE is not present in the current
|
||
(A;;LCRP;;;BA) ACE is not present in the current
|
||
[y/N/all/none] y
|
||
Fixed attribute 'nTSecurityDescriptor' of 'CN=Deleted Objects,DC=samba,DC=org'
|
||
|
||
The change should be confirmed with 'y' for all objects starting with
|
||
'CN=Deleted Objects'.
|
||
|
||
|
||
Changes since 4.19.2
|
||
--------------------
|
||
|
||
o Douglas Bagnall <douglas.bagnall@catalyst.net.nz>
|
||
* BUG 15520: sid_strings test broken by unix epoch > 1700000000.
|
||
|
||
o Ralph Boehme <slow@samba.org>
|
||
* BUG 15487: smbd crashes if asked to return full information on close of a
|
||

Release Notes for Samba 4.19.0
|
||
September 04, 2023
|
||
==============================
|
||
|
||
This is the first stable release of the Samba 4.19 release series.
|
||
Please read the release notes carefully before upgrading.
|
||
|
||
NEW FEATURES/CHANGES
|
||
====================
|
||
|
||
Migrated smbget to use common command line parser
|
||
-------------------------------------------------
|
||
|
||
The smbget utility implemented its own command line parsing logic. After
|
||
discovering an issue we decided to migrate it to use the common command line
|
||
parser. This has some advantages as you get all the feature it provides like
|
||
Kerberos authentication. The downside is that breaks the options interface.
|
||
The support for smbgetrc has been removed. You can use an authentication file
|
||
if needed, this is documented in the manpage.
|
||
|
||
Please check the smbget manpage or --help output.
|
||
|
||
gpupdate changes
|
||
----------------
|
||
|
||
The libgpo.get_gpo_list function has been deprecated in favor of
|
||
an implementation written in python. The new function can be imported via
|
||
`import samba.gp`. The python implementation connects to Active Directory
|
||
using the SamDB module, instead of ADS (which is what libgpo uses).
|
||
|
||
Improved winbind logging and a new tool for parsing the winbind logs
|
||
--------------------------------------------------------------------
|
||
|
||
Winbind logs (if smb.conf 'winbind debug traceid = yes' is set) contain new
|
||
trace header fields 'traceid' and 'depth'. Field 'traceid' allows to track the
|
||
trace records belonging to the same request. Field 'depth' allows to track the
|
||
request nesting level. A new tool samba-log-parser is added for better log
|
||
parsing.
|
||
|
||
AD database prepared to FL 2016 standards for new domains
|
||
---------------------------------------------------------
|
||
|
||
While Samba still provides only Functional Level 2008R2 by default,
|
||
Samba as an AD DC will now, in provision ensure that the blank
|
||
database is already prepared for Functional Level 2016, with AD Schema
|
||
2019.
|
||
|
||
This preparation is of the default objects in the database, adding
|
||
containers for Authentication Policies, Authentication Silos and AD
|
||
claims in particular. These DB objects must be updated to allow
|
||
operation of the new features found in higher functional levels.
|
||
|
||
Kerberos Claims, Authentication Silos and NTLM authentication policies
|
||
----------------------------------------------------------------------
|
||
|
||
An initial, partial implementation of Active Directory Functional
|
||
Level 2012, 2012R2 and 2016 is available in this release.
|
||
|
||
In particular Samba will issue Active Directory "Claims" in the PAC,
|
||
for member servers that support these, and honour in-directory
|
||
configuration for Authentication Policies and Authentication Silos.
|
||
|
||
The primary limitation is that while Samba can read and write claims
|
||
in the directory, and populate the PAC, Samba does not yet use them
|
||
for access control decisions.
|
||
|
||
While we continue to develop these features, existing domains can
|
||
test the feature by selecting the functional level in provision or
|
||
raising the DC functional level by setting
|
||
|
||
ad dc functional level = 2016
|
||
|
||
in the smb.conf
|
||
|
||
The smb.conf file on each DC must have 'ad dc functional level = 2016'
|
||
set to have the partially complete feature available. This will also,
|
||
at first startup, update the server's own AD entry with the configured
|
||
functional level.
|
||
|
||
For new domains, add these parameters to 'samba-tool provision'
|
||
|
||
--option="ad dc functional level = 2016" --function-level=2016
|
||
|
||
The second option, setting the overall domain functional level
|
||
indicates that all DCs should be at this functional level.
|
||
|
||
To raise the domain functional level of an existing domain, after
|
||
updating the smb.conf and restarting Samba run
|
||
samba-tool domain schemaupgrade --schema=2019
|
||
samba-tool domain functionalprep --function-level=2016
|
||
samba-tool domain level raise --domain-level=2016 --forest-level=2016
|
||
|
||
Improved KDC Auditing
|
||
---------------------
|
||
|
||
As part of the auditing required to allow successful deployment of
|
||
Authentication Policies and Authentication Silos, our KDC now provides
|
||
Samba-style JSON audit logging of all issued Kerberos tickets,
|
||
including if they would fail a policy that is not yet enforced.
|
||
Additionally most failures are audited, (after the initial
|
||
pre-validation of the request).
|
||
|
||
Kerberos Armoring (FAST) Support for Windows clients
|
||
----------------------------------------------------
|
||
|
||
In domains where the domain controller functional level is set, as
|
||
above, to 2012, 2012_R2 or 2016, Windows clients will, if configured
|
||
via GPO, use FAST to protect user passwords between (in particular) a
|
||
workstation and the KDC on the AD DC. This is a significant security
|
||
improvement, as weak passwords in an AS-REQ are no longer available
|
||
for offline attack.
|
||
|
||
Claims compression in the AD PAC
|
||
--------------------------------
|
||
|
||
Samba as an AD DC will compress "AD claims" using the same compression
|
||
algorithm as Microsoft Windows.
|
||
|
||
Resource SID compression in the AD PAC
|
||
--------------------------------------
|
||
|
||
Samba as an AD DC will now correctly populate the various PAC group
|
||
membership buffers, splitting global and local groups correctly.
|
||
|
||
Additionally, Samba marshals Resource SIDs, being local groups in the
|
||
member server's own domain, to only consume a header and 4 bytes per
|
||
group in the PAC, not a full-length SID worth of space each. This is
|
||
known as "Resource SID compression".
|
||
|
||
Resource Based Constrained Delegation (RBCD) support in both MIT and Heimdal
|
||
-----------------------------------------------------------------------------
|
||
|
||
Samba AD DC built with MIT Kerberos (1.20 and later) has offered RBCD
|
||
support since Samba 4.17. Samba 4.19 brings this feature to the
|
||
default Heimdal KDC.
|
||
|
||
Samba 4.17 added to samba-tool delegation the 'add-principal' and
|
||
'del-principal' subcommands in order to manage RBCD, and the database
|
||
changes made by these tools are now honoured by the Heimdal KDC once
|
||
Samba is upgraded.
|
||
|
||
Likewise, now both MIT (1.20 and later) and Heimdal KDCs add the
|
||
Asserted Identity [1] SID into the PAC for constrained delegation.
|
||
|
||
[1] https://docs.microsoft.com/en-us/windows-server/security/kerberos/kerberos-constrained-delegation-overview
|
||
|
||
New samba-tool support for silos, claims, sites and subnets.
|
||
------------------------------------------------------------
|
||
|
||
samba-tool can now list, show, add and manipulate Authentication Silos
|
||
(silos) and Active Directory Authentication Claims (claims).
|
||
|
||
samba-tool can now list and show Active Directory sites and subnets.
|
||
|
||
A new Object Relational Model (ORM) based architecture, similar to
|
||
that used with Django, has been built to make adding new samba-tool
|
||
subcommands simpler and more consistent, with JSON output available
|
||
standard on these new commands.
|
||
|
||
Updated GnuTLS requirement / in-tree cryptography removal
|
||
----------------------------------------------------------
|
||
|
||
Samba requires GnuTLS 3.6.13 and prefers GnuTLS 3.6.14 or later.
|
||
|
||
This has allowed Samba to remove all of our in-tree cryptography,
|
||
except that found in our Heimdal import. Samba's runtime cryptography
|
||
needs are now all provided by GnuTLS.
|
||
|
||
(The GnuTLS vesion requirement is raised to 3.7.2 on systems without
|
||
the Linux getrandom())
|
||
|
||
We also use Python's cryptography module for our testing.
|
||
|
||
The use of well known cryptography libraries makes Samba easier for
|
||
end-users to validate and deploy, and for distributors to ship. This
|
||
is the end of a very long journey for Samba.
|
||
|
||
Updated Heimdal import
|
||
----------------------
|
||
|
||
Samba's Heimdal branch (known as lorikeet-heimdal) has been updated to
|
||
the current pre-8.0 (master) tree from upstream Heimdal, ensuring that
|
||
this vendored copy, included in our release remains as close as
|
||
possible to the current upstream code.
|
||
|
||
Revocation support in Heimdal KDC for PKINIT certificates
|
||
---------------------------------------------------------
|
||
|
||
Samba will now correctly honour the revocation of 'smart card'
|
||
certificates used for PKINIT Kerberos authentication.
|
||
|
||
This list is reloaded each time the file changes, so no further action
|
||
other than replacing the file is required. The additional krb5.conf
|
||
option is:
|
||
|
||
[kdc]
|
||
pkinit_revoke = FILE:/path/to/crl.pem
|
||
|
||
Information on the "Smart Card login" feature as a whole is at:
|
||
https://wiki.samba.org/index.php/Samba_AD_Smart_Card_Login
|
||
|
||
Protocol level testsuite for (Smart Card Logon) PKINIT
|
||
------------------------------------------------------
|
||
|
||
Previously Samba's PKINIT support in the KDC was tested by use of
|
||
shell scripts around the client tools of MIT or Heimdal Kerberos.
|
||
Samba's independently written python testsuite has been extended to
|
||
validate KDC behaviour for PKINIT.
|
||
|
||
Require encrypted connection to modify unicodePwd on the AD DC
|
||
--------------------------------------------------------------
|
||
|
||
Setting the password on an AD account on should never be attempted
|
||
over a plaintext or signed-only LDAP connection. If the unicodePwd
|
||
(or userPassword) attribute is modified without encryption (as seen by
|
||
Samba), the request will be rejected. This is to encourage the
|
||
administrator to use an encrypted connection in the future.
|
||
|
||
NOTE WELL: If Samba is accessed via a TLS frontend or load balancer,
|
||
the LDAP request will be regarded as plaintext.
|
||
|
||
Samba AD TLS Certificates can be reloaded
|
||
-----------------------------------------
|
||
|
||
The TLS certificates used for Samba's AD DC LDAP server were
|
||
previously only read on startup, and this meant that when then expired
|
||
it was required to restart Samba, disrupting service to other users.
|
||
|
||
smbcontrol ldap_server reload-certs
|
||
|
||
This will now allow these certificates to be reloaded 'on the fly'
