Echo: samba: security update to 2:4.13.2+dfsg-2

medium Tenable Self-Hosted Container Security Plugin ID 459367

Description

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

 - A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to
 crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short
 delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it
 returns. The Samba DNS server itself will continue to operate, but many RPC services will not.

Solution

Update the samba library and its related packages to version 2:4.13.2+dfsg-2 or later.
