A NULL pointer dereference, or possible use-after-free flaw was found in
Samba AD LDAP server in versions before 4.10.17, before 4.11.11 and before
4.12.4. Although some versions of Samba shipped with Red Hat Enterprise
Linux do not support Samba in AD mode, the affected code is shipped with
the libldb package. This flaw allows an authenticated user to possibly
trigger a use-after-free or NULL pointer dereference. The highest threat
from this vulnerability is to system availability.
