Summary

OpenSSH: Mehrere Schwachstellen

Severity

Mittel

Scope

3 vulnerabilities in this advisory, including CVE-2016-1907.

CVE-2016-1907

Es existiert eine Denial of Service Schwachstelle in OpenSSH im Zusammenhang mit "ssh_packet_restore_state()" und Roaming. Ein anonymer, entfernter Angreifer kann diese Schwachstelle nutzen, um den OpenSSH-Client zum Absturz zu bringen. Das Problem besteht darin, dass beim erneuten Aufbau der Verbindung nicht der globale Pointer "backup_state" verwendet wird und dieser dann bei der Weitergabe an "ssh_packet_restore_state()" noch immer den Wert NULL hat.

Known affected: 22 products
