A flaw was found in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4 in the way it processed NetBios over TCP/IP. This flaw allows a remote attacker could to cause the Samba server to consume excessive CPU use, resulting in a denial of service. This highest threat from this vulnerability is to system availability. Se encontró un fallo en todas las versiones de Samba anteriores a 4.10.17, anteriores a 4.11.11 y anteriores a 4.12.4 en la manera en que procesaba NetBios sobre TCP/IP. Este fallo permite a un atacante remoto poder causar que el servidor Samba consuma un uso excesivo de la CPU, resultando en una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00002.html https://bugzilla.redhat.com/show_bug.cgi?id=1849491%3B https://lists.debian.org/debian-lts-announce/2020/11/msg00041.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6YLNQ5GRXUKYRUAOFZ4DUBVN4SMTL6Q2 https://security.gentoo.org/glsa/202007- • CWE-400: Uncontrolled Resource Consumption •

A flaw was found when using samba as an Active Directory Domain Controller. Due to the way samba handles certain requests as an Active Directory Domain Controller LDAP server, an unauthorized user can cause a stack overflow leading to a denial of service. The highest threat from this vulnerability is to system availability. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2.

All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the (poorly named) dnsserver RPC pipe provides administrative facilities to modify DNS records and zones. Samba, when acting as an AD DC, stores DNS records in LDAP. In AD, the default permissions on the DNS partition allow creation of new records by authenticated users. This is used for example to allow machines to self-register in DNS. If a DNS record was created that case-insensitively matched the name of the zone, the ldb_qsort() and dns_name_compare() routines could be confused into reading memory prior to the list of DNS entries when responding to DnssrvEnumRecords() or DnssrvEnumRecords2() and so following invalid memory as a pointer. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html http://www.openwall.com/lists/oss-security/2024/06/24/3 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14861 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE https:/&#x • CWE-276: Incorrect Default Permissions •

All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the S4U (MS-SFU) Kerberos delegation model includes a feature allowing for a subset of clients to be opted out of constrained delegation in any way, either S4U2Self or regular Kerberos authentication, by forcing all tickets for these clients to be non-forwardable. In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable. However the Samba AD DC does not do that for S4U2Self and does set the forwardable flag even if the impersonated client has the not-delegated flag set. Todas las versiones de Samba 4.xx anteriores a 4.9.17, versiones 4.10.x anteriores a 4.10.11 y versiones 4.11.x anteriores a 4.11.3, presentan un problema, donde el modelo de delegación de Kerberos S4U (MS-SFU) incluye una funcionalidad que permite a un subconjunto de clientes ser excluidos de la delegación restringida de cualquier manera, ya sea S4U2Self o autenticación Kerberos regular, al forzar que todos los tickets para estos clientes no sean reenviables. En AD, esto es implementado mediante un atributo de usuario delegation_not_allowed (también se conoce como no delegado), que se traduce como no permitido-reenviable. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14870 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2022/11/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE https: • CWE-285: Improper Authorization CWE-287: Improper Authentication •
