Description:
The talk software makes it possible for users to send and receive messages across
systems through a terminal session. The talk client, which allows initialization of talk
sessions, is installed by default.
Rationale:
The software presents a security risk as it uses unencrypted protocols for
communication.
Impact:
Many insecure service clients are used as troubleshooting tools and in testing
environments. Uninstalling them can inhibit capability to test and troubleshoot. If they
are required it is advisable to remove the clients after use to prevent accidental or
intentional misuse.
Audit:
Verify talk is not installed. The following command may provide the needed
information:
# dpkg-query -W -f='${binary:Package}\t${Status}\t${db:Status-Status}\n' talk
talk unknown ok not-installed not-installed
