* Fri Jul 12 2024 Arkady L. Shane <tigro@msvsphere-os.ru> - 2.12.0-2
- Rebuilt for MSVSphere 8.10

* Fri Dec 29 2023 Paul Howarth <paul@city-fan.org> - 2.12.0-2
- Address CVE 2023-48795 (a.k.a. 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 always attempt to use "strict kex" mode if offered by the
    server, unless you override this by specifying 'strict_kex=False' in
    'Transport.__init__'
  - 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
- 'Transport' grew a new 'packetizer_class' kwarg for overriding the
  packet-handler class used internally; this is mostly for testing, but advanced
  users may find this useful when doing deep hacks
- A handful of lower-level classes (notably 'paramiko.message.Message' and
  'paramiko.pkey.PKey') previously returned 'bytes' objects from their
  implementation of '__str__', even under Python 3, and there was never any
  '__bytes__' method; these issues have been fixed by renaming '__str__' to
  '__bytes__' and relying on Python's default "stringification returns the
  output of '__repr__'" behavior re: any real attempts to 'str()' such objects

* Sun Nov 06 2022 Paul Howarth <paul@city-fan.org> - 2.12.0-1
- Update to 2.12.0 (rhbz#2140281)
  - Add a 'transport_factory' kwarg to 'SSHClient.connect' for advanced users
    to gain more control over early Transport setup and manipulation (GH#2054,
    GH#2125)
  - Update '~paramiko.client.SSHClient' so it explicitly closes its wrapped
    socket object upon encountering socket errors at connection time; this
    should help somewhat with certain classes of memory leaks, resource
    warnings, and/or errors (though we hasten to remind everyone that Client
    and Transport have their own '.close()' methods for use in non-error
    situations!) (GH#1822)
  - Raise '~paramiko.ssh_exception.SSHException' explicitly when blank private
    key data is loaded, instead of the natural result of 'IndexError'; this
    should help more bits of Paramiko or Paramiko-adjacent codebases to
    correctly handle this class of error (GH#1599, GH#1637)
- Use SPDX-format license tag

* Fri Jul 22 2022 Fedora Release Engineering <releng@fedoraproject.org> - 2.11.0-3
- Rebuilt for https://fedoraproject.org/wiki/Fedora_37_Mass_Rebuild

* Tue Jun 14 2022 Python Maint <python-maint@redhat.com> - 2.11.0-2
- Rebuilt for Python 3.11

* Tue May 17 2022 Paul Howarth <paul@city-fan.org> - 2.11.0-1
- Update to 2.11.0
  - Align signature verification algorithm with OpenSSH re: zero-padding
    signatures that don't match their nominal size/length; this shouldn't
    affect most users, but will help Paramiko-implemented SSH servers handle
    poorly behaved clients such as PuTTY (GH#1933)
  - OpenSSH 7.7 and older has a bug preventing it from understanding how to
    perform SHA2 signature verification for RSA certificates (specifically
    certs - not keys), so when we added SHA2 support it broke all clients using
    RSA certificates with these servers; this has been fixed in a manner similar
    to what OpenSSH's own client does - a version check is performed and the
    algorithm used is downgraded if needed (GH#2017)
  - Recent versions of Cryptography have deprecated Blowfish algorithm support;
    in lieu of an easy method for users to remove it from the list of
    algorithms Paramiko tries to import and use, we've decided to remove it
    from our "preferred algorithms" list, which will both discourage use of a
    weak algorithm, and avoid warnings (GH#2038, GH#2039)
  - Windows-native SSH agent support as merged in 2.10 could encounter
    'Errno 22' 'OSError' exceptions in some scenarios (e.g. server not cleanly
    closing a relevant named pipe); this has been worked around and should be
    less problematic (GH#2008, GH#2010)
  - Add SSH config token expansion (eg '%h', '%p') when parsing 'ProxyJump'
    directives (GH#1951)
  - Apply unittest 'skipIf' to tests currently using SHA1 in their critical
    path, to avoid failures on systems starting to disable SHA1 outright in
    their crypto backends (e.g. RHEL 9) (GH#2004, GH#2011)

* Tue Apr 26 2022 Paul Howarth <paul@city-fan.org> - 2.10.4-1
- Update to 2.10.4
  - Update 'camelCase' method calls against the 'threading' module to be
    'snake_case'; this and related tweaks should fix some deprecation warnings
    under Python 3.10 (GH#1838, GH#1870, GH#2028)
  - '~paramiko.pkey.PKey' instances' '__eq__' did not have the usual safety
    guard in place to ensure they were being compared to another 'PKey' object,
    causing occasional spurious 'BadHostKeyException', among other things
    (GH#1964, GH#2023, GH#2024)
  - Servers offering certificate variants of hostkey algorithms (e.g.
    'ssh-rsa-cert-v01@openssh.com') could not have their host keys verified by
    Paramiko clients, as it only ever considered non-cert key types for that
    part of connection handshaking (GH#2035)

* Mon Mar 21 2022 Paul Howarth <paul@city-fan.org> - 2.10.3-2
- Skip tests that would fail without SHA-1 signing support in backend, such as
  on EL-9 (GH#2011)

* Sat Mar 19 2022 Paul Howarth <paul@city-fan.org> - 2.10.3-1
- Update to 2.10.3
  - Certificate-based pubkey auth was inadvertently broken when adding SHA2
    support in version 2.9.0 (GH#1963, GH#1977)
  - Switch from module-global to thread-local storage when recording thread IDs
    for a logging helper; this should avoid one flavor of memory leak for
    long-running processes (GH#2002, GH#2003)

* Tue Mar 15 2022 Paul Howarth <paul@city-fan.org> - 2.10.2-1
- Update to 2.10.2
  - Fix Python 2 compatibility breakage introduced in 2.10.1 (GH#2001)
- Re-enable sftp tests, no longer failing under mock
