Vendor Statements (disclaimer)

Official Statement from Red Hat (07/21/2008)

Upon investigating this issue, the Red Hat Security Response Team has determined that this is not a vulnerability. The ability to specify a desired role when connecting to OpenSSH is a feature of how OpenSSH interacts with SELinux. Users can only assign themselves SELinux roles which they have permission to access. They cannot assign themselves arbitrary roles.
