Announcement:



Packaging status

Dear all,

I am pleased to announce the new bugfix release, version 1.4.2 of getdns The two major bugfixes are:

  • DNSSEC Denial of Existence validation at NSEC wildcards, which was broken since 1.4.0.

  • Null termination of strings in configuration dictionaries. This in particular affected Stubby configurations with settings for trust_anchors_url, trust_anchors_verify_CA, trust_anchors_verify_email, appdata_dir, resolvconf, hosts, tls_ca_path, tls_ca_file, tls_cipher_list and tls_curves_list. If you use Stubby and had one of these configured, but they did not affect Stubby operation as expected, retry with this release candidate to see if it resolves the issue.

DNSSEC validation in stub mode has been improved and should be possible more often now (also with badly behaving authoritatives), because it is now partly traced from the root up.

A few more issues are resolved with this release. For a complete overview see the ChangeLog below.

This release has Stubby release 0.2.3 included, with:

  • An updated stubby.yml file (Watch out! The entries for securedns.eu have changed!)
  • Better recommendations for running Stubby with systemd
  • No pass through of ENDS0 options that were handled by underlying getdns
