**Name of the Vulnerable Software and Affected Versions** Wireshark versions 2.4.0 through 2.4.7 Wireshark versions 2.6.0 through 2.6.1 **Description** The CoAP protocol dissector in Wireshark could crash due to a NULL condition not being properly checked. This issue was addressed by modifying the `epan/dissectors/packet-coap.c` file. **Recommendations** For Wireshark versions 2.4.0 through 2.4.7, update to a version where the NULL condition in the CoAP protocol dissector is properly checked. For Wireshark versions 2.6.0 through 2.6.1, update to a version where the NULL condition in the CoAP protocol dissector is properly checked.
