Bump dnspython from 2.3.0 to 2.8.0

[dependabot]

Bumps dnspython from 2.3.0 to 2.8.0.

Release notes

Sourced from dnspython's releases.

dnspython 2.7.0

See What's New for details.

The minimum supported version of Python is 3.9.

My thanks to the many people who have contributed to this release. Also thanks to my co-maintainers: Tomáš Křížek, Petr Špaček, and Brian Wellington.

dnspython 2.6.1

See What's New for details.

This is a bug fix release for 2.6.0 where the "TuDoor" fix erroneously suppressed legitimate Truncated exceptions. This caused the stub resolver to timeout instead of failing over to TCP when a legitimate truncated response was received over UDP.

This release addresses the potential DoS issue discussed in the "TuDoor" paper (CVE-2023-29483). The dnspython stub resolver is vulnerable to a potential DoS if a bad-in-some-way response from the right address and port forged by an attacker arrives before a legitimate one on the UDP port dnspython is using for that query. In this situation, dnspython might switch to querying another resolver or give up entirely, possibly denying service for that resolution. This release addresses the issue by adopting the recommended mitigation, which is ignoring the bad packets and continuing to listen for a legitimate response until the timeout for the query has expired.

Thank you to all the contributors to this release, and, as usual, thanks to my co-maintainers: Tomáš Křížek, Petr Špaček, and Brian Wellington.

Changelog

Sourced from dnspython's changelog.

2.8.0

• dns/btreezone.py provides another zone versioned implementation built on top of a B-tree. It maintains DNSSEC sort order, labels nodes as delegation points or glue, and can find the "bounds" of a name (useful for DNSSEC responses).

• dns/query.py now provides make_socket(), make_ssl_socket(), and make_ssl_context() to make using persistent connections with the query code easier.

• dns/win32util.py now supports explicitly setting the configuration method used to get system dns info, using the set_config_method() function. There is a new configuration method that uses the Win32 API, which can be set using set_config_method(ConfigMethod.Win32). We are considering making the Win32 API the default in the future as we believe it to be the most accurate. Any feedback on it compared to the other methods is welcome.

• The DSYNC record is now supported. This type is still in draft stage at the IETF and is subject to change.

• The minimum supported Python version is now 3.10.

2.7.0

• dns.query.https() and dns.asyncquery.https() now support HTTP/3 and the http_version parameter may be used to specify which version to use.

• If the cryptography module is installed, then dnspython will now create deterministic ECDSA signatures by default. Cryptography, if installed, must be at least version 43. Thanks to Jakob Schlyter for adding the feature.

• The RESINFO and WALLET RdataTypes are now supported.

• The COOKIE and Report-Channel EDNS0 options are now supported.

• All supported RdataTypes can now be imported at a single time rather than lazily on first use by calling dns.rdata.load_all_types().

• The SVCB and HTTPS records now support the ohttp parameter.

• xfr() and inbound_xfr() now share a common implementation.

• Tokens are now supported for QUIC and HTTP/3.

• dns.message.from_wire() now saves the input wire format in the Message's "wire" attribute. Likewise, dns.message.Message.to_wire() now records the generated wire format in that attribute.

• The dns.message.Message object now has a get_options() helper to retrieve EDNS0
