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.
