We have RHEL v6.9 server and OpenSSH v5.3p1 is installed on it (confirmed by rpm -q openssh which outputs openssh-5.3p1-123.el6_9.x86_64). After the security testing, we are asked to upgrade OpenSSH to v7.3, to avoid any vulnerabilities.

I have tried yum update openssh and it says

No Packages marked for Update

Any idea, how can I update openssh? Is it even possible to update it to 7.3 on RHEL 6.9?

You’re using the latest officially packaged version of OpenSSH on RHEL 6.9, which is still supported (and will be, without an extended support contract, until late 2020):

OpenSSH package information from the RHEL customer portal, including the list of versions

This means that all known vulnerabilities in your version of openssh are fixed, and newly-discovered vulnerabilities which are discovered in the future will be fixed — there’s no need to upgrade to the latest version of OpenSSH to avoid vulnerabilities.

That’s one of the points of using a supported distribution: you can rely on your distributor to take care of upstream vulnerabilities for you (as long as you keep your systems up-to-date).

To upgrade to OpenSSH 7.4 you’d have to upgrade to RHEL 7, or build it yourself for RHEL 6 (and take on support for future vulnerabilities).

  • Thanks for the detailed reply, however I can't access that officially packaged version of OpenSSH because I don't have a subscription there. Could you please share any screenshot of that page so I can use it as proof? Thanks in advance.

  • Hopefully someone in your organisation has access to that page, since you’re running RHEL... I’ve added a screenshot with the dropdown. There’s a message in the background stating that a more recent version is available, but that’s referring to the RHEL 7 versions. Commented Oct 31, 2017 at 8:58
