Echo: samba: security update to 2:4.17.8+dfsg-1

high Tenable Self-Hosted Container Security Plugin ID 458683

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A vulnerability was found in Samba where a delegated administrator with permission to create objects in
 Active Directory can write to all attributes of the newly created object, including security-sensitive
 attributes, even after the object's creation. This issue occurs because the administrator owns the object
 due to the lack of an Access Control List (ACL) at the time of creation and later being recognized as the
 'creator owner.' The retained significant rights of the delegated administrator may not be well
 understood, potentially leading to unintended privilege escalation or security risks. (CVE-2020-25720)

Solution

Update the samba library and its related packages to version 2:4.17.8+dfsg-1 or later.
