NVD Description

Note: Versions mentioned in the description apply only to the upstream samba-ad-dc-libs package and not the samba-ad-dc-libs package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an account modification re-adds an SPN that was previously present on that account, such as one added when a computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an attacker who can intercept traffic can impersonate existing services, resulting in a loss of confidentiality and integrity.
