Release Notes for Samba 4.18.1
March 29, 2023
==============================
This is a security release in order to address the following defects:
o CVE-2023-0225: An incomplete access check on dnsHostName allows authenticated
but otherwise unprivileged users to delete this attribute from
any object in the directory.
https://www.samba.org/samba/security/CVE-2023-0225.html
o CVE-2023-0922: 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.
https://www.samba.org/samba/security/CVE-2023-0922.html
o CVE-2023-0614: 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.
