Discussion

The dtspc service deals with the CDE interface of the X11 daemon. It is started automatically by the inetd daemon in response to a CDE client requesting a process to be started on the daemon's host. This makes it vulnerable to buffer overflow attacks, which may allow an attacker to gain root privileges on a host. This service must be disabled unless it is absolutely required.

Check Content

From the command prompt, execute the following command: 
# grep "^dtspc[[:blank:]]" /etc/inetd.conf

If there is any output from the command, this is a finding.

Fix Text

In "/etc/inetd.conf", comment out the "dtspc" entry by running command: 
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'dtspc' -p 'tcp'

Restart inetd:
# refresh -s inetd
