In this article they said that a vulnerability has been discovered in samba.

In this same article, they said that the maintainer of samba had already patched the vulnerability in the versions 4.6.4/4.5.10/4.4.14. And they also said in the article that Ubuntu and Redhat has already released patched versions.

The problem is : the samba version that is installed on my Ubuntu 17.04 is 4.5.8 (I used the command samba --version to get this information).

So did Ubuntu release a patched version of samba ? and if yes, how does it come that I have the version 4.5.8 and not the 4.5.10 which is patched.

PS : I updated my computer today with sudo apt update && sudo apt upgrade.

    You say in paragraph 3 that you have version 5.4.8, but then you say in the next paragraph that you have version 4.5.8.

Ubuntu released security updates for this on 2017-05-24, see Ubuntu Security Notice USN-3296-1.

As usually Ubuntu doesn't provide the new upstream version but patched the versions for all the supported releases to keep the changes at a minimum.
