IMPORTANT: Because both client and server applications are affected by these vulnerabilities, we advise users to reboot their systems after installing these updates. Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.

https://access.redhat.com/errata/RHSA-2002:157 - FixedRed Hat Stronghold 4redhat_csaf
We have backported the security fixes for the versions of OpenSSL and mm included in Stronghold 4. The fixed packages are now available via the update agent service; run $ bin/agent from the Stronghold 4 install root to upgrade an existing Stronghold 4 installation to the new package versions. Due to a bug in the update agent, users of Solaris on Intel platforms should create a file "conf/update-agent.conf" in the install root, containing the following two lines: [agent] ignore: RPMPROB_FILTER_IGNOREARCH After the appropriate updates have been applied, it will be necessary to manually restart the server with the following commands: $ bin/stop-server $ bin/start-server
