[Samba] How to apply the security patch ?

[Alexsandro Oliveira]

Hello guys
.
I am Brazilian and I'm using google translate to ask some questions.
The question is the following:

How do I apply this patch on my samba?
Can I apply this patch on my active server on the client? My server is a
primary domain controller with internal DNS.

Note: My Server is a Debian 8 and the samba was installed via source code.

Grateful .
