PuTTY 0.85.0.0 SSH and Telnet Client

PuTTY is a free, open-source client program designed for Windows and Unix platforms that implements the SSH, Telnet, Rlogin, and SUPDUP network protocols. It serves as a terminal emulator and network client, allowing users to establish secure remote sessions on other computers over a network. The software is particularly useful for system administrators and developers who need to manage remote Unix or Linux machines from a Windows environment. By acting as the client end of the session, PuTTY displays the remote console output locally, enabling you to work on a distant machine as if you were sitting directly at its console.

Key features:

• Supports SSH, Telnet, Rlogin, and SUPDUP network protocols for remote connectivity.
• Includes an xterm terminal emulator for displaying remote session output.
• Functions as a client for running remote sessions on Unix and Windows machines.
• Part of a suite that includes puttygen, plink, and psftp utilities.
• Designed for secure remote administration and development tasks.
• Compatible with both Windows and Unix operating systems.

What's new in version 0.85.0.0:

• Fixed a remotely triggerable use-after-free vulnerability in Pageant.
• Resolved a remotely triggerable buffer overflow issue related to OpenSSH encrypt-then-MAC cipher modes.
• Addressed a buffer overflow in private key decryption that could be triggered by maliciously constructed keys.
• Implemented denial-of-service security fixes to prevent tight loops and unlimited memory consumption at startup.
