"This are security releases 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. https://www.samba.org/samba/security/CVE-2023-0614.html"
These CVEs appear to have been fixed in 4.18.1, released 29th March, see https://www.samba.org/samba/history/ However, more recent is 4.18.2 which was released Apr 19, 2023; release notes at https://www.samba.org/samba/history/samba-4.18.2.html
In addition to bumping 4.17 (to 4.17.8) - https://bugs.gentoo.org/906104 and presumably 4.18 (to 4.18.2) and 4.16 (to 4.16.10) we may also want to drop 4.15 given it is marked as EOL per https://wiki.samba.org/index.php/Samba_Release_Planning
