| 2 | # |
| 3 | # Description |
| 4 | # =========== |
| 5 | # The talk software makes it possible for users to send and receive messages |
| 6 | # across systems through a terminal session. The talk client, which allows |
| 7 | # initialization of talk sessions, is installed by default. |
| 8 | # |
| 9 | # Rationale |
| 10 | # ========= |
| 11 | # The software presents a security risk as it uses unencrypted protocols |
| 12 | # for communication. |
| 13 | # |
| 14 | # Audit |
| 15 | # ===== |
| 16 | # Run the following command and verify talk is not installed: |
| 17 | # |
| 18 | # dpkg -s talk |
| 19 | # |
| 20 | # Remediation |
| 21 | # =========== |
| 22 | # Run the following command to uninstall talk : |
| 23 | # |
| 24 | # apt-get remove talk |
| 25 | # |
| 26 | # Impact |
| 27 | # ====== |
| 28 | # Many insecure service clients are used as troubleshooting tools and in |
| 29 | # testing environments. Uninstalling them can inhibit capability to test |
| 30 | # and troubleshoot. If they are required it is advisable to remove the clients |
| 31 | # after use to prevent accidental or intentional misuse. |
