Description

This security bulletin contains information about 1 security vulnerability.


1) Improper access control (CVE-ID: CVE-2018-14628)

The vulnerability allows a remote user to gain access to sensitive information.

The vulnerability exists due to improper access restrictions when Samba is an Active Directory Domain Controller. When a domain was provisioned with an unpatched Samba version, the ntSecurityDescriptor is simply inherited from Domain/Partition-HEAD-Object instead of being very strict (as on a Windows provisioned domain). This means also non privileged users can use the LDAP_SERVER_SHOW_DELETED_OID control in order to view, the names and preserved attributes of deleted objects.


Remediation

Install update from vendor's website.
