Paramiko (a combination of the esperanto words for paranoid and friend) is
a module for python 2.3 or greater that implements the SSH2 protocol for
secure (encrypted and authenticated) connections to remote machines. Unlike
SSL (aka TLS), the SSH2 protocol does not require heirarchical 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 an encrypted tunnel. (This is how sftp works, for example.)

Security Fix(es):

  • Race condition in the write_private_key_file function (CVE-2022-24302)
