The vulnerability leads to a segmentation fault in the SSH dissector, which can crash Wireshark or TShark, but only when the user opens a malicious capture file or analyzes traffic containing malformed SSH packets. Since exploitation requires user interaction (opening the file) or the ability to inject traffic into a monitored network, and the consequence is restricted to denial of service rather than compromise of confidentiality or integrity, the severity is classified as moderate.", "threat_severity": "Moderate"}
