Red Hat mitigation
To mitigate this issue, users can disable the Monero protocol dissector in Wireshark. This prevents the vulnerable code from being executed when analyzing network traffic containing Monero protocol data. To disable the dissector: 1. Open Wireshark. 2. Go to `Analyze` -> `Enabled Protocols...`. 3. In the `Enabled Protocols` dialog, uncheck the box next to `Monero`. 4. Click `OK`. Alternatively, users can avoid opening untrusted network trace files. Disabling the dissector may affect the ability to analyze legitimate Monero protocol traffic.
