✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Disable the SPDY protocol dissector in Wireshark or TShark to prevent processing of the vulnerable protocol format. For TShark command-line usage, pass the protocol disable flag: ``` tshark --disable-protocol spdy -r <capture_file> ``` For persistent configuration across sessions, append the protocol to the disabled protocols file: ``` echo "spdy" >> ~/.config/wireshark/disabled_protos ``` In the Wireshark graphical interface: 1. Navigate to Analyze -> Enabled Protocols... 2. Search for "SPDY" and clear the checkbox. 3. Click OK or Save. Caveat: Disabling the dissector prevents the decoding and inspection of SPDY protocol streams, treating them as generic TCP or TLS payload. Wireshark must be restarted if it is currently running for configuration changes to take effect. Always ensure capture analysis is conducted with non-privileged user privileges.
