Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets. Los aceptadores de Kerberos necesitan un acceso fácil a los identificadores estables de AD (por ejemplo, objectSid). Samba como un DC AD ahora proporciona una manera para que las aplicaciones de Linux para obtener un SID confiable (y samAccountName) en los boletos emitidos • https://bugzilla.redhat.com/show_bug.cgi?id=2021728 https://bugzilla.samba.org/show_bug.cgi?id=14725 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2020-25721.html • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2020-25719
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. Se encontró un fallo en la forma en que Samba, como controlador de dominio de Active Directory, implementaba la autenticación basada en nombres de Kerberos.
