Updates twisted from 24.11.0 to 26.4.0rc2

Release notes

Sourced from twisted's releases.

Twisted 26.4.0rc2 (2026-04-29)

This is the last release with support for Python 3.9.

Security

• twisted.names was fix for Denial of Service (DoS) attack via resource exhaustion during DNS name decompression. Reported and fixed by Tomas Illuminati Balbin CVE-2026-42304 (#12626)

Features

• twisted.internet.ssl.CertificateOptions has a new constructor argument, contextForServerName, which takes a callback that will get invoked when a client sends a server name indication, with the sent servername, and returns a new OpenSSL.SSL.Context that the connection will switch to. (#4887)
• twisted.internet.endpoints.serverFromString now supports the tls endpoint type, which allows you to do twist web --listen=tls:.../certbot-dir/config/live pointed at a certbot live configuration directory and have your certbot certificates automatically discovered and served appropriately. (#9885)
• twisted.internet.reactor now has type annotations and will appear to be an object of an appropriate type, allowing for idiomatic common usages with correct type information. (#9909)
• twisted.conch.ssh.SSHUserAuthServer now supports the security key ssh types "sk-ecdsa-sha2-nistp256@openssh.com" and "sk-ssh-ed25519@openssh.com" and extracting the application property from these new key types. (#12212)

Bugfixes

• twisted.internet.mail will now return a meaningful Failure when TLS validation fails. (#10210)
• TLS version range constraints passed to twisted.internet.ssl.CertificateOptions are now properly respected rather than excluding the version being passed as the desired constraint. (#10232)
• A potential reference cycle that might cause intermittent memory spikes while using twisted.internet.defer.inlineCallbacks was removed. (#12120)
• Trial no longer emits the error RuntimeWarning: TestResult has no addDuration method when running PyUnit tests. (#12229)
• twisted.python.rebuild.rebuild() now handles changes to sys.modules gracefully. Prior to the change, it could possibly raise a "dictionary changed size during iteration" error if the module list changed. (#12458)
• twisted.internet.protocol.ReconnectingClientFactory: Don't multiply by factor for initial delay, but use initialDelay directly. (#12478)
• twisted.internet.ssl and twisted.protocols.tls no longer mutate the pyOpenSSL context after creating pyOpenSSL connections, maintaining compatibility with an upcoming version of pyOpenSSL and increasing reliability (possibly even fixing a very rare segfault) (#12500)
• twisted.internet.testing.MemoryReactor.callWhenRunning now invokes the callback immediately, if already started. (#12514)
• Twisted now correctly detects EOF on OpenSSL 4. (#12632)

Improved Documentation

• The example code from the documentation describing how to create a custom DNS server was updated to Python3. (#12480)
• Type annotations now use modern PEP 585 built-in generics and PEP 604 union syntax throughout the project. (#12556)

Updates cryptography from 46.0.7 to 50.0.1

Changelog

Sourced from cryptography's changelog.

50.0.1 - 2026-08-25

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 4.0.2.
.. _v50-0-0:
50.0.0 - 2026-07-31

• SECURITY ISSUE: :func:~cryptography.hazmat.primitives.serialization.pkcs7.pkcs7_decrypt_der and its PEM and S/MIME variants no longer expose distinguishable errors or timing when unwrapping a RecipientInfo's encryptedKey, which could act as a Bleichenbacher oracle for callers that decrypt untrusted messages. A random key is now substituted on failure, as described in :rfc:3218. Credit to @​X1AOxiang for reporting the issue. CVE-2026-69247
• Deprecated Diffie-Hellman key exchange over finite fields (FFDH). Everything FFDH is deprecated, including the types in cryptography.hazmat.primitives.asymmetric.dh and loading FFDH keys or parameters with the key loading APIs. Users should migrate to a more modern key exchange algorithm.
• Added xof() class methods to :class:~cryptography.hazmat.primitives.hashes.SHAKE128 and :class:~cryptography.hazmat.primitives.hashes.SHAKE256 for constructing algorithm instances configured for use with :class:~cryptography.hazmat.primitives.hashes.XOFHash.
• The :mod:X.509 verification <cryptography.x509.verification> APIs are now considered stable and are subject to our API stability policy.
• Added the :doc:/cobblestone recipe, an implementation of the Cobblestone-128 and Cobblestone-256 instantiations of the C2SP chunked-encryption specification <https://c2sp.org/chunked-encryption>_ for streaming authenticated encryption of large messages.
• Parsing a Signed Certificate Timestamp list now rejects encodings that carry trailing bytes after the list or after an individual SCT, instead of silently ignoring them.
• Added support for using :class:~cryptography.x509.Name as a field type in the :doc:/hazmat/asn1/index module.
• Loading a public key or an EC private key now rejects DER where the subjectPublicKey (or EC publicKey) BIT STRING declares a non-zero number of unused bits, instead of silently ignoring it.
• Parsing a CRL entry's InvalidityDate extension now rejects a GeneralizedTime that carries fractional seconds or another non-DER form, matching the strict encoding already required for every other X.509 time field.
• :func:~cryptography.x509.ocsp.load_der_ocsp_request and :func:~cryptography.x509.ocsp.load_der_ocsp_response now reject a request or response whose version field is not v1, the only version defined by RFC 6960, matching the version validation already performed when loading

Updates pyasn1 from 0.6.3 to 0.6.4

Release notes

Sourced from pyasn1's releases.

Release 0.6.4

This is a security release.

• CVE-2026-59885 (GHSA-8ppf-4f7h-5ppj): Fixed quadratic time complexity in the OBJECT IDENTIFIER and RELATIVE-OID decoders. A small crafted substrate encoding many arcs could consume excessive CPU.
• CVE-2026-59884 (GHSA-m4p7-r5rc-7g4j): Limited BER long-form tag IDs to 20 octets (140 bits). Unbounded tag IDs allowed a crafted substrate to consume excessive CPU and memory.
• CVE-2026-59886 (GHSA-hm4w-wwcw-mr6r): Fixed excessive memory and CPU consumption in Real.__float__() for values with large base-10 exponents.
• Pinned PyPI publish GitHub Action to an immutable commit.

All changes are noted in the CHANGELOG.

Revision 0.6.4, released 08-07-2026

• CVE-2026-59885 (GHSA-8ppf-4f7h-5ppj): Fixed quadratic time complexity in the OBJECT IDENTIFIER and RELATIVE-OID decoders. A small crafted substrate encoding many arcs could consume excessive CPU. Arcs are now accumulated in linear time; decoded values are unchanged (thanks for reporting, tynus2)
• CVE-2026-59884 (GHSA-m4p7-r5rc-7g4j): Limited BER long-form tag IDs to 20 octets (140 bits), matching the OID arc limit introduced in 0.6.2. Unbounded tag IDs allowed a crafted substrate to consume excessive CPU and memory; longer tag IDs are now rejected with PyAsn1Error. Also fixed Tag and TagSet repr() failing on huge tag (thanks for reporting, mikeappsec) IDs due to the integer-to-string conversion limit (Python 3.11+)
• CVE-2026-59886 (GHSA-hm4w-wwcw-mr6r): Fixed excessive memory and CPU consumption in Real.float() for values with large base-10 exponents. Conversion no longer materializes huge intermediate integers; values too large to represent as a Python float raise OverflowError promptly, and prettyPrint() renders them as '' as before. Also fixed base-10 mantissa normalization to use exact integer arithmetic; mantissas larger than 2**53 could previously lose precision through float division (thanks for reporting, gvozdila)
• Pinned PyPI publish GitHub Action to an immutable commit [pr #113](pyasn1/pyasn1#113)
