Dnspython 2.6.1 is now available on PyPI<\/a>.<\/p>\n

See What’s New<\/a> for details.<\/p>\n

This is a bug fix release for 2.6.0 where the “TuDoor” fix erroneously\nsuppressed legitimate Truncated exceptions. This caused the stub\nresolver to timeout instead of failing over to TCP when a legitimate\ntruncated response was received over UDP.<\/p>\n

This release addresses the potential DoS issue discussed in the\n“TuDoor” paper (CVE-2023-29483). The dnspython stub resolver is\nvulnerable to a potential DoS if a bad-in-some-way response from the\nright address and port forged by an attacker arrives before a\nlegitimate one on the UDP port dnspython is using for that query. In\nthis situation, dnspython might switch to querying another resolver or\ngive up entirely, possibly denying service for that resolution. This\nrelease addresses the issue by adopting the recommended mitigation,\nwhich is ignoring the bad packets and continuing to listen for a\nlegitimate response until the timeout for the query has expired.<\/p>"},{"title":"2.6.0","link":"https:\/\/www.dnspython.org\/news\/2.6.0\/","pubDate":"Fri, 16 Feb 2024 12:15:00 -0800","guid":"https:\/\/www.dnspython.org\/news\/2.6.0\/","description":"

Dnspython is a DNS toolkit for Python. It can be used for queries,\nzone transfers, dynamic updates, nameserver testing, and many other\nthings.<\/p>\n

Dnspython provides both high and low level access to the DNS. The high\nlevel classes perform queries for data of a given name, type, and\nclass, and return an answer set. The low level classes allow direct\nmanipulation of DNS zones, messages, names, and records. Almost all\nRR types are supported.<\/p>"},{"title":"2.5.0","link":"https:\/\/www.dnspython.org\/news\/2.5.0\/","pubDate":"Sat, 20 Jan 2024 05:00:00 -0800","guid":"https:\/\/www.dnspython.org\/news\/2.5.0\/","description":"
