Description:


   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
