The samldb_check_user_account_control_acl function in
dsdb/samdb/ldb_modules/samldb.c in Samba 4.x before 4.1.22, 4.2.x before
4.2.7, and 4.3.x before 4.3.3 does not properly check for administrative
privileges during creation of machine accounts, which allows remote
authenticated users to bypass intended access restrictions by leveraging
the existence of a domain with both a Samba DC and a Windows DC, a similar
issue to CVE-2015-2535.
