Echo: samba: security update to 2:4.16.0+dfsg-2

high Tenable Self-Hosted Container Security Plugin ID 461803

Description

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

- The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that
SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an
account modification re-adds an SPN that was previously present on that account, such as one added when a
computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to
perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an
attacker who can intercept traffic can impersonate existing services, resulting in a loss of
confidentiality and integrity. (CVE-2022-0336)

Solution

Update the samba library and its related packages to version 2:4.16.0+dfsg-2 or later.
