2.11.0:
- [Feature] Add SSH config token expansion (eg %h, %p) when parsing
ProxyJump directives. Patch courtesy of Bruno Inec.
- [Support] (via #2011) 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 (eg RHEL
9). Report & patch via Paul Howarth.
- [Support] 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. Thanks to Karthikeyan
Singaravelan for the report, @Narendra-Neerukonda for the patch,
and to Thomas Grainger and Jun Omae for patch workshopping.
- [Support] 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. This will
both discourage use of a weak algorithm, and avoid warnings. Credit
for report/patch goes to Mike Roest.
2.10.5:
- [Bug] Windows-native SSH agent support as merged in 2.10 could
encounter Errno 22 OSError exceptions in some scenarios (eg server
not cleanly closing a relevant named pipe). This has been worked
around and should be less problematic. Reported by Danilo Campana
Fuchs and patched by Jun Omae.
- [Bug] 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. Reported by Adarsh Chauhan, with fix
suggested by Jun Omae.
- [Bug] Align signature verification algorithm with OpenSSH re:
zero-padding signatures which 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. Thanks to
Jun Omae for catch & patch.
