<summary>Recommended update for python-Whoosh, python-paramiko, python-pyOpenSSL</summary>
<description>This update for python-Whoosh, python-paramiko, python-pyOpenSSL fixes the following issues:
python-paramiko was updated to 2.1.3:
* Make util.log_to_file append instead of replace.
* SSHClient and Transport could cause a memory leak if there’s a connection
problem or protocol error, even if Transport.close() is called.
* Prior support for ecdsa-sha2-nistp(384|521) algorithms didn’t fully extend
to covering host keys, preventing connection to hosts which only offer
these key types and no others. This is now fixed.
* Prefer newer ecdsa-sha2-nistp keys over RSA and DSA keys during host key
selection. This improves compatibility with OpenSSH, both in terms of general
behavior, and also re: ability to properly leverage OpenSSH-modified
known_hosts files.
* The RC4/arcfour family of ciphers has been broken since version 2.0; but since
the algorithm is now known to be completely insecure, we are opting
to remove support outright instead of fixing it.
* Move sha1 above the now-arguably-broken md5 in the list of preferred MAC
algorithms, as an incremental security improvement for users whose target
systems offer both.
* Writing encrypted/password-protected private key files was silently broken
since 2.0 due to an incorrect API call
Includes a directly related fix, namely adding the ability to read AES-256-CBC
ciphered private keys (which is now what we tend to write out as it is
Cryptography’s default private key cipher.)
* Allow any type implementing the buffer API to be used with BufferedFile,
Channel, and SFTPFile. This resolves a regression introduced in 1.13
with the Python 3 porting changes, when using types such as memoryview.
* Enhance default cipher preference order such that aes(192|256)-cbc are preferred
over blowfish-cbc.
* SSHClient now requests the type of host key it has (e.g. from known_hosts)
and does not consider a different type to be a “Missing” host key. This fixes
a common case where an ECDSA key is in known_hosts and the server also has
an RSA host key.
update to 2.1.2:
* Fix a bug in server-mode concerning multiple interactive auth steps
* SSHClient now gives its internal Transport a handle on itself, preventing
garbage collection of the client until the session is closed. Without this,
some code which returns stream or transport objects without the client that
generated them, would result in premature session closure
when the client was GCd
* Avoid test suite exceptions on platforms lacking errno.ETIME
* weak how RSAKey.__str__ behaves so it doesn’t cause TypeError under Python 3.
update to 2.1.1:
* A tweak to the original patch implementing gh#398 was not fully applied,
causing calls to ~paramiko.client.SSHClient.invoke_shell to fail with
AttributeError. This has been fixed.
* Fix the implementation of PKey.write_private_key_file (this method is only
publicly defined on subclasses; the fix was in the private real
implementation) so it passes the correct params to open()
* Add an optional timeout parameter to Transport.start_clienti
<paramiko.transport.Transport.start_client> (and feed it the value of the
configured connection timeout when used within SSHClient
<paramiko.client.SSHClient>.)
* Catch AssertionError thrown by Cryptography when attempting to load bad
ECDSA keys, turning it into an SSHException.
* Add a missing .closed attribute (plus ._closed because reasons) to
ProxyCommand <paramiko.proxy.ProxyCommand>
* Make the subprocess import in proxy.py lazy so users on platforms without
it (such as Google App Engine) can import Paramiko successfully
* Fix incorrect docstring/param-list for Transport.auth_gssapi_keyex
<paramiko.transport.Transport.auth_gssapi_keyex> so it matches
the real signature.
* Add an environment dict argument to Client.exec_command
update to 2.0.2:
* [Bug] #758: Apply type definitions to _winapi module from
jaraco.windows 3.6.1. This should address issues on Windows platforms
that often result in errors like ArgumentError: [...] int too long to
convert. Thanks to @swohlerLL for the report and Jason R. Coombs for the
patch.
* [Bug] #774: Add a _closed private attribute to Channel objects so that
they continue functioning when used as proxy sockets under Python 3 (e.g.
as direct-tcpip gateways for other Paramiko connections.)
* [Bug] #673: (via #681) Fix protocol banner read errors (SSHException)
which would occasionally pop up when using ProxyCommand gatewaying.
Thanks to @Depado for the initial report and Paul Kapp for the fix.
update to 2.0.1:
* [Bug] #537: Fix a bug in BufferedPipe.set_event which could cause
deadlocks/hangs when one uses select.select against Channel objects (or
otherwise calls Channel.fileno after the channel has closed).
* [Bug] #520: (Partial fix) Fix at least one instance of race condition
driven threading hangs at end of the Python interpreter session.
(Includes a docs update as well - always make sure to .close() your
clients!)
update to 2.0.0:
* Add support for 384- and 512-bit elliptic curve groups in ECDSA
key types (aka ecdsa-sha2-nistp384 / ecdsa-sha2-nistp521).
* Due to an earlier bugfix, less-specific Host blocks' ProxyCommand
values were overriding ProxyCommand none in more-specific Host
blocks. This has been fixed in a backwards compatible manner (i.e.
ProxyCommand none continues to appear as a total lack of any
proxycommand key in parsed config structures).
* Fix a backwards incompatibility issue that cropped up in
SFTPFile.prefetch <~paramiko.sftp_file.prefetch> re: the
erroneously non-optional file_size parameter. Should only affect
users who manually call prefetch.
* Replace PyCrypto with the Python Cryptographic Authority (PyCA)
'Cryptography' library suite. This improves security,
installability, and performance; adds PyPy support; and much more.
* Fix stalled/hung SFTP downloads by cleaning up some threading lock
issues.
* Fix a Python 3 compatibility issue when handling two-factor
authentication.
* Clean up setup.py to always use setuptools, not doing so was a
historical artifact from bygone days.
* Update the module in charge of handling SSH moduli so it's
consistent with OpenSSH behavior re: prime number selection.
* Fix up ~paramiko.ssh_exception.NoValidConnectionsError so it
pickles correctly, and fix a related Python 3 compatibility issue.
* Update to jaraco.windows 3.4.1 to fix some errors related to
ctypes on Windows platforms.
* Annotate some public attributes on ~paramiko.channel.Channel such
as .closed.
* Fix logic bug in the SFTP client's callback-calling functionality;
previously there was a chance the given callback would fire twice
at the end of a transfer.
* Identify & work around a race condition in the test for handshake
timeouts, which was causing frequent test failures for a subset of
contributors as well as Travis-CI (usually, but not always,
limited to Python 3.5).
* Remove whitespace in our setup.py's install_requires as it
triggers occasional bugs in some versions of setuptools.
* Strip trailing/leading whitespace from lines when parsing SSH
config files - this brings things in line with OpenSSH behavior.
* Fix behavior of gssapi-with-mic auth requests so they fail
gracefully (allowing followup via other auth methods) instead of
raising an exception.
* Add missing file-like object methods for ~paramiko.file.BufferedFile
and ~paramiko.sftp_file.SFTPFile.
update to version 1.16.0:
* Streamline use of stat when downloading SFTP files via
SFTPClient.get <paramiko.sftp_client.SFTPClient.get>; this avoids
triggering bugs in some off-spec SFTP servers such as IBM
Sterling. Thanks to @muraleee for the initial report and to Torkil
Gustavsen for the patch.
* Fully enable two-factor authentication (e.g. when a server
requires AuthenticationMethods
pubkey,keyboard-interactive). Thanks to @perryjrandall for the
patch and to @nevins-b and Matt Robenolt for additional support.
* Fix 'exec' requests in server mode to use get_string instead of
get_text to avoid UnicodeDecodeError on non-UTF-8 input. Thanks to
Anselm Kruis for the patch & discussion.
* Fix line number reporting in log output regarding invalid
known_hosts line entries. Thanks to Dylan Thacker-Smith for catch
& patch.
update to version 1.15.2 (bsc#962291)
* [Bug] #320: Update our win_pageant module to be Python 3 compatible
* [Bug] #429: Server-level debug message logging was overlooked during the
Python 3 compatibility update; Python 3 clients attempting to log SSH
debug packets encountered type errors. This is now fixed
* [Bug] #459: Tighten up agent connection closure behavior to avoid
spurious ResourceWarning display in some situations
* [Bug] #266: Change numbering of Transport channels to start at 0
instead of 1 for better compatibility with OpenSSH & certain server
implementations which break on 1-indexed channels
* [Support] #419: Modernize a bunch of the codebase internals to
leverage decorators. Props to @beckjake for realizing we’re no longer
on Python 2.2 :D
* [Support] #421: Modernize threading calls to user newer API
* [Support] #422: Clean up some unused imports
* [Support] #431: Replace handrolled ssh_config parsing code with
use of the shlex module
* [Bug] #415: Fix ssh_config parsing to correctly interpret ProxyCommand
none as the lack of a proxy command, instead of as a literal command
string of "none"
* [Bug] #428: Fix an issue in BufferedFile (primarily used in the SFTP
modules) concerning incorrect behavior by readlines on files whose
size exceeds the buffer size
* [Bug] #455: Tweak packet size handling to conform better to the
OpenSSH RFCs; this helps address issues with interactive program cursors
* [Bug] #413: (also #414, #420, #454) Be significantly smarter about polling
& timing behavior when running proxy commands, to avoid unnecessary
(often 100%!) CPU usage
new upsteam version 1.15.1
* fixed from previous version: [Bug] #399: SSH agent forwarding
would hang due to incorrect values passed into the new window
size arguments for Transport
* detailed changelog available on pramiko website:
http://paramiko-www.readthedocs.org/en/latest/changelog.html
python-pyOpenSSL was updated to version 17.1.0.
Backward-incompatible changes:
* Removed the deprecated ``OpenSSL.rand.egd()`` function.
Applications should prefer ``os.urandom()`` for random number generation.
`#630 <https://github.com/pyca/pyopenssl/pull/630>`_
* Removed the deprecated default ``digest`` argument to ``OpenSSL.crypto.CRL.export()``.
Callers must now always pass an explicit ``digest``.
`#652 <https://github.com/pyca/pyopenssl/pull/652>`_
* Fixed a bug with ``ASN1_TIME`` casting in ``X509.set_notBefore()``,
``X509.set_notAfter()``, ``Revoked.set_rev_date()``, ``Revoked.set_nextUpdate()``,
and ``Revoked.set_lastUpdate()``. You must now pass times in the form
``YYYYMMDDhhmmssZ``. ``YYYYMMDDhhmmss+hhmm`` and ``YYYYMMDDhhmmss-hhmm``
will no longer work. `#612 <https://github.com/pyca/pyopenssl/pull/612>`_
Deprecations:
* Deprecated the legacy "Type" aliases: ``ContextType``, ``ConnectionType``,
``PKeyType``, ``X509NameType``, ``X509ExtensionType``, ``X509ReqType``,
``X509Type``, ``X509StoreType``, ``CRLType``, ``PKCS7Type``, ``PKCS12Type``,
``NetscapeSPKIType``.
The names without the "Type"-suffix should be used instead.
Changes:
* Added ``OpenSSL.crypto.X509.from_cryptography()`` and ``OpenSSL.crypto.X509.to_cryptography()``
for converting X.509 certificate to and from pyca/cryptography objects.
`#640 <https://github.com/pyca/pyopenssl/pull/640>`_
* Added ``OpenSSL.crypto.X509Req.from_cryptography()``, ``OpenSSL.crypto.X509Req.to_cryptography()``,
``OpenSSL.crypto.CRL.from_cryptography()``, and ``OpenSSL.crypto.CRL.to_cryptography()``
for converting X.509 CSRs and CRLs to and from pyca/cryptography objects.
`#645 <https://github.com/pyca/pyopenssl/pull/645>`_
* Added ``OpenSSL.debug`` that allows to get an overview of used library versions (including
linked OpenSSL) and other useful runtime information using ``python -m OpenSSL.debug``.
`#620 <https://github.com/pyca/pyopenssl/pull/620>`_
* Added a fallback path to ``Context.set_default_verify_paths()`` to accommodate the upcoming
release of ``cryptography`` ``manylinux1`` wheels.
`#633 <https://github.com/pyca/pyopenssl/pull/633>`_
python-Whoosh is shipped in version 2.7.4.
