usually all upgrades are done through the package manager ...yum, yumex, packagekit etc

Can you provide some actual details about your system?? Version/distro of Linux, version of SSH, etc???

As said, most distros can upgrade these things via online repositories, and a lot of system services like these will upgrade automatically.

Contact Red Hat and get your system up to date.

OpenSSH

RHEL tends to lag behind several versions from time to time. IF you find you cannot get the version you require, the other option is to install the development packages (make, autoconfig, gcc, etc) and the source packages you need to compile your own (zlib-devel, openssl-devel, openssh-devel) and compile and install them in the proper order. Read the README and INSTALL files for dependencies, you may need to add additional packages.

I do not generally recommend the "compile your own" solution, because forever after you need to worry that your package manager will mess up the install. It cannot help you maintain or protect installed packages if you go outside the repository system. Only do this if you must, and try to install to alternate paths (under /opt/freeware or /usr/local instead of / and /bin) to segregate your packages for the system set.

I'm sure if the OP contacts Red Hat, they will explain that the version of openssh provided to subscribers is "backported" with all necessary security patches according to their policy: https://access.redhat.com/security/updates/backporting/

RHEL

I am sure they will, but that may not be the issue.
Security patches backported to earlier versions close off the attack vectors, but do not provide the more advanced and secure modes of operation. We have not asked WHY the OP wants the 5.9 version, so I made no assumption about the objective.

Why would you want a cutting edge version of sshd on rhelif you know there are poential costly downsides to implementing this deployment?

I made an assumption that the OP's objective was a stable, secure, and up-to-date Red Hat system. (It appears OP has not applied recommended updates since Jan 2009! What is the benefit of installing bleeding-edge SSH on a system that is otherwise outdated and missing 3 years of security patches?) "Contact Red Hat" is a reasonable first step toward resolving this issue, agree?
