KB-10597: SELinux is preventing sshd (unconfined_t) "dyntransition" to <Unknown> (unconfined_t)

*ERROR: * user@host[/rhome/user]: sealert -l dfbcb39e-031e-4518-ad52-d79144164e02
*Summary: * SELinux is preventing sshd (unconfined_t) "dyntransition" to <Unknown> (unconfined_t).

This error is commonly seen in older versions of RedHat systems (RHEL 5.x), where sshd is running with "unconfined_t" when later versions of RHEL run with "sshd_t". The error is resolved in more recent versions of the RHEL operating system. If an upgrade is not a viable possibility a work-around is available using the following steps.

1. Download the attached file "sshdyn.pp.gz"
2. Unzip the package
3. As root, run "semodule -i sshdyn.pp"

This enables and allows SSHD to perform dynamic type transitions.
