Descriptions
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.
Todas las versiones de Samba versiones 4.x.x 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 en el que la tubería RPC dnsserver (pobremente nombrada) provee instalaciones administrativas para modificar registros y zonas DNS. Samba, cuando actúa como AD DC, almacena registros DNS en LDAP. En AD, los permisos predeterminados en la partición DNS permiten la creación de nuevos registros por parte de usuarios autenticados. Esto es usado, por ejemplo, para permitir que las máquinas se registren automáticamente en DNS. Si un registro DNS fue creado que no distingue entre mayúsculas y minúsculas el nombre de la zona, las rutinas ldb_qsort() y dns_name_compare() podrían ser confundidas en la memoria de lectura antes de la lista de entradas DNS al responder a la función DnssrvEnumRecords() o DnssrvEnumRecords2() y entonces seguir la memoria inválida como un puntero.
