Comment 11 Huzaifa S. Sidhpurwala 2015-11-20 06:42:09 UTC

This flaw can be mitigated in wireshark by disabling the WCP protocol dissector. In wireshark GUI application click on Analyze->Enabled Protocols and search for "WCP" 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 "WCP" to it. This should disable the WCP protocol.
