Produktbeschreibung: PuTTY ist ein freier, Open Source Terminal Emulator der als Client für SSH, Telnet, rlogin und die Serielle Konsole dient. FileZilla ist eine Software zur Dateiübertragung. WinSCP dient dem sicheren Dateitransfer auf Basis von SSH. TortoiseGit ist eine grafische Benutzeroberfläche für die Versionsverwaltungssoftware Git.
Angriff: Ein entfernter, anonymer Angreifer kann eine Schwachstelle in PuTTY und Anwendungen, die PuTTY nutzen, wie z.B. FileZilla, WinSCP und TortoiseGit ausnutzen, um bei 521-bit ECDSA den privaten Schlüssel des Nutzers zu erlangen.
