Security update for putty

This update for putty fixes the following issues:

putty was updated to to release 0.80:

  • Fix CVE-2023-48795 [boo#1218128]

  • Update to release 0.79

    • Terminal mouse tracking: support for mouse movements which are not drags, and support for horizontal scroll events (e.g. generated by trackpads).
    • Fixed: PuTTY could fail an assertion if a resize control sequence was sent by the server while the window was docked to one half of the screen in KDE.
    • Fixed: PuTTY could fail an assertion if you tried to change the font size while the window was maximised.

  • Update to release 0.78

    • Support for OpenSSH certificates, for both user authentication keys and host keys.
    • New SSH proxy modes, for running a custom shell command or subsystem on the proxy server instead of forwarding a port through it.
    • New plugin system to allow a helper program to provide responses in keyboard-interactive authentication, intended to automate one-time password systems.
    • Support for NTRU Prime post-quantum key exchange,
    • Support for AES-GCM (in the OpenSSH style rather than RFC 5647).
    • Support for more forms of Diffie-Hellman key exchange: new larger integer groups (such as group16 and group18), and support for using those and ECDH with GSSAPI.
    • Bug fix: server-controlled window title setting now works again even if the character set is ISO 8859 (or a few other

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.
