RF4CE protocol dissector crash in 4.6.0 to 4.6.8 and 4.4.0 to 4.4.18 allows denial of service
A flaw was found in Wireshark. By convincing a user to open a specially crafted capture file containing malformed Radio Frequency for Consumer Electronics (RF4CE) network traffic, an attacker can cause the RF4CE protocol dissector to crash. This issue primarily results in a Denial of Service (DoS) by terminating the application.
Меры по смягчению последствий
Disable the RF4CE dissector in Wireshark or tshark to prevent processing of malformed packets:
- Graphical user interface: Navigate to Analyze -> Enabled Protocols, search for "RF4CE", uncheck the checkbox, and click OK.
- Command-line interface (tshark): Invoke tshark with the protocol disabled:
- Configuration file: Add the protocol identifier to the disabled protocols configuration file:
Caveats: Disabling the RF4CE dissector prevents Wireshark from decoding RF4CE frames, displaying them only as raw payload data. Active Wireshark processes must be restarted for configuration file changes to take effect. As a general operational security practice, do not run Wireshark or tshark with elevated (root) privileges when inspecting untrusted capture files.
