SSH2 Module for Python
Paramiko is a module for python 2.2 (or higher) that implements the
SSH2 protocol for secure (encrypted and authenticated) connections to
remote machines.
Unlike SSL (aka TLS), the SSH2 protocol does not require hierarchical
certificates signed by a powerful central authority. you may know SSH2
as the protocol that replaced telnet and rsh for secure access to
remote shells, but the protocol also includes the ability to open
arbitrary channels to remote services across the encrypted tunnel --
this is how sftp works, for example.
It is written entirely in python (no C or platform-dependent code) and
is released under the GNU LGPL (lesser GPL).

- Update to 3.4.0: (CVE-2023-48795, bsc#1218168)
* Transport grew a new packetizer_class kwarg for overriding the
packet-handler class used internally.
* Address CVE 2023-48795 (aka the "Terrapin Attack", a vulnerability found
in the SSH protocol re: treatment of packet sequence numbers) as follows:
+ The vulnerability only impacts encrypt-then-MAC digest algorithms in
tandem with CBC ciphers, and ChaCha20-poly1305; of these, Paramiko
currently only implements hmac-sha2-(256|512)-etm in tandem with
AES-CBC.
+ As the fix for the vulnerability requires both ends of the connection
to cooperate, the below changes will only take effect when the remote
end is OpenSSH >= 9.6 (or equivalent, such as Paramiko in server mode,
as of this patch version) and configured to use the new
"strict kex" mode.
+ Paramiko will now raise an SSHException subclass (MessageOrderError)
when protocol messages are received in unexpected order. This includes
situations like receiving MSG_DEBUG or MSG_IGNORE during initial key
exchange, which are no longer allowed during strict mode.
+ Key (re)negotiation -- i.e. MSG_NEWKEYS, whenever it is encountered --
now resets packet sequence numbers. (This should be invisible to users
during normal operation, only causing exceptions if the exploit is
encountered, which will usually result in, again, MessageOrderError.)
+ Sequence number rollover will now raise SSHException if it occurs
during initial key exchange (regardless of strict mode status).
* Tweak ext-info-(c|s) detection during KEXINIT protocol phase; the
original implementation made assumptions based on an OpenSSH
implementation detail.
- Add patch use-64-bit-maxsize-everywhere.patch:
* Use the 64-bit value of sys.maxsize.
