Remediation
Red Hat mitigation
This flaw can be mitigated in wireshark by disabling the X11 protocol dissector. In wireshark GUI application click on Analyze->Enabled Protocols and search for "X11" and disable in. When using "tshark", the text interface, create a file called "disabled_protos" in the preferences folder (normally .wireshark folder in the home directory of the user running wireshark) and add "X11" to it. This should disable the X11 protocol.
