SAMBA+ 4.18.1, 4.17.7 and 4.16.10 have just been released. These are important security releases, please update affected systems as soon as possible. The packages are available for various SUSE and Red Hat platforms as well as for Debian GNU/Linux, Ubuntu and AIX.

The packages address the following security related issues, which only affect the Samba AD DC and related tools:

• CVE-2023-0614 Access controlled AD LDAP attributes can be discovered.
  The fix in 4.6.16, 4.7.9, 4.8.4 and 4.9.7 for CVE-2018-10919 Confidential attribute disclosure via LDAP filters was insufficient and an attacker may be able to obtain confidential BitLocker recovery keys from a Samba AD DC.
  
  Installations with such secrets in their Samba AD should assume they have been obtained and need replacing.
   
• CVE-2023-0225 Samba AD DC "dnsHostname" attribute can be deleted by unprivileged authenticated users.
  An incomplete access check on dnsHostName allows authenticated but otherwise unprivileged users to delete this attribute from any object in the directory.
  
  Affects only Samba 4.17.0 and later versions.  
   
• CVE-2023-0922 Samba AD DC admin tool samba-tool sends passwords in cleartext.
  The Samba AD DC administration tool, when operating against a remote LDAP server, will by default send new or reset passwords over a signed-only connection.

On May 9, 2023, a workshop by Stefan Kania with the title "How to set up a Samba Domain?" will be held as part of sambaXP. The location of the event is the Hotel FREIZEIT IN in Göttingen, Germany. The workshop is primarily aimed at newcomers and beginners and is intended, among other things, to help in deciding whether a Samba Active Directory is the right choice, and how to deploy it successfully. Tickets as well as the detailed contents of the workshop are available at https://sambaXP.org.

Especially for help with AD selection there is the possibility to ask individual questions. In a practical part a Samba domain with two domain controllers and a file server will be set up. The following contents will be discussed for example:

• Quick and easy setup of a Samba domain
• Different client operating systems
• Windows compliant permissions.

A VM suitable for this purpose will be provided to the participants, an own PC is necessary. More detailed information about the requirements for the device can be found at https://sambaxp.org. The workshop will be held in English.

Stefan Kania is an author and trainer in the field of Samba, LDAP and Kerberos. He has already published several technical books in which he has contributed his expertise and many years of experience.
