A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC (read-only domain controller). This would allow an RODC to print administrator tickets. Se encontró un fallo en la forma en que samba, como controlador de dominio de Active Directory, es capaz de soportar un RODC (controlador de dominio de sólo lectura). Esto permitiría a un RODC imprimir tickets de administrador • https://bugzilla.redhat.com/show_bug.cgi?id=2019726 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2020-25718.html • CWE-862: Missing Authorization •

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. El AD DC de Samba, podía confundirse sobre el usuario que representa un ticket si no requería estrictamente un PAC de Kerberos y siempre usaba los SIDs encontrados dentro. • https://bugzilla.redhat.com/show_bug.cgi?id=2019732 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2020-25719.html https://access.redhat.com/security/cve/CVE-2020-25719 • CWE-287: Improper Authentication CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb database. However while the database was correctly shared, the user credentials state was only pointed at, and when one connection within that association group ended, the database would be left pointing at an invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-after-free could instead allow different user state to be pointed at and this might allow more privileged access. En DCE/RPC es posible compartir los manejadores (cookies para el estado de los recursos) entre múltiples conexiones por medio de un mecanismo llamado "association groups". • https://bugzilla.redhat.com/show_bug.cgi?id=2021726 https://bugzilla.samba.org/show_bug.cgi?id=14468 https://security.gentoo.org/glsa/202309-06 https://www.samba.org/samba/security/CVE-2021-3738.html • CWE-416: Use After Free •
