PuTTY ist ein Open Source Client-Programm für die Netzwerkprotokolle SSH, Telnet und Rlogin, mit dem verschlüsselte Verbindungen zu Remote-Rechnern hergestellt werden kann.
These features are new in 0.72 (released 2019-07-20):
Security fixes found by the EU-funded bug bounty:
two separate vulnerabilities affecting the obsolete SSH‑1 protocol, both available before host key checking
a vulnerability in all the SSH client tools (PuTTY, Plink, PSFTP and PSCP) if a malicious program can impersonate Pageant
Bug fix: crash in GSSAPI / Kerberos key exchange affecting third-party GSSAPI providers on Windows (such as MIT Kerberos for Windows)
Bug fix: crash in GSSAPI / Kerberos key exchange triggered if the server provided an ordinary SSH host key as part of the exchange
Bug fix: trust sigils were never turned off in SSH‑1 or Rlogin
Bug fix: trust sigils were never turned back on if you used Restart Session
Bug fix: PSCP in SCP download mode could create files with a spurious newline at the end of their names
Bug fix: PSCP in SCP download mode with the -p option would generate spurious complaints about illegal file renaming
Bug fix: the initial instruction message was never printed during SSHkeyboard-interactive authentication
Bug fix: pasting very long lines through connection sharing could crash the downstream PuTTY window
Bug fix: in keyboard layouts with a ‘,’ key on the numeric keypad (e.g. German), Windows PuTTY would generate ‘.’ instead for that key
Bug fix: PuTTYgen could generate RSA keys with a modulus one bit shorter than requested
