Solaris services running ttsession process

A new vulnerability has been found that exploits ttsession process running on Solaris servers (versions 2.6, 2.7, 8, 9, 10) to gain root access. We need to understand which underlying Solaris system services can run ttsession process. The known service that runs is ttdbserver but there are some references on the internet to desktop services like dtlogin and CDE Calendar as well. Can someone please provide clarity on which services should be stopped and disabled (or any specific configuration parameters be changed) in order to remove any residual risk of exploits caused due to ttsession process? Thanks.
