Dear Knot Resolver users, Knot Resolver 6.4.1 has been released! Security: - DNS-over-QUIC (DoQ) had severe issues, allowing even RCE Many people reported (some of) these issues to us. - DNSSEC correctness issues, acting mainly through the aggressive cache: * dealing with Labels field in RRSIGs being smaller than the signer's * dealing with NSEC's next-name pointing outside of the zone Special thanks to Qifan Zhang from Palo Alto Networks. Improvements: - docker: upgrade to Debian 13 (!1856) - update IANA's certificate for root trust anchor bootstrapping (!1845) Bugfixes: - /local-data/addresses*: make multiple addresses work (#808, #954) - views: fix protocol-based matching for DoQ Full changelog: https://gitlab.nic.cz/knot/knot-resolver/raw/v6.4.1/NEWS Sources: https://knot-resolver.nic.cz/release/knot-resolver-6.4.1.tar.xz GPG signature: https://knot-resolver.nic.cz/release/knot-resolver-6.4.1.tar.xz.asc Documentation: https://www.knot-resolver.cz/documentation/v6.4.1/ -- Ales Mrazek PGP: 3057 EE9A 448F 362D 7420 5A77 9AB1 20DA 0A76 F6DE

by Aleš Mrázek

Dear Knot Resolver users, Knot Resolver 5.7.7 has been released! Security: - DNSSEC correctness issues, acting mainly through the aggressive cache: * dealing with Labels field in RRSIGs being smaller than the signer's * dealing with NSEC's next-name pointing outside of the zone Special thanks to Qifan Zhang from Palo Alto Networks. Improvements: - support cmocka 2.0.0 - avoid AD=1 in reply if ANSWER+AUTHORITY are empty (#914) - packaging: rpm: require python3-setuptools (!1831) - packaging: rpm: provide user/group (!1838) This should also resolve the issue with user and group configuration during installation (GH#130). - make DoH cache-control header respect our cache's TTL limits (!1832) - support libdnssec merged into libknot, as planned for knot >= 3.6 (!1833) - update IANA's certificate for root trust anchor bootstrapping (!1862) Bugfixes: - respect disablement of QNAME case randomization even after TCP issues - cache: fix wrong TTL in some cases, typically 32768 - reduce excessive caching of some uncommon failed answers (!1832) - dns64: fix CNAME problems again (#797, !1862) Full changelog: https://gitlab.nic.cz/knot/knot-resolver/raw/v5.7.7/NEWS Sources: https://knot-resolver.nic.cz/release/knot-resolver-5.7.7.tar.xz GPG signature: https://knot-resolver.nic.cz/release/knot-resolver-5.7.7.tar.xz.asc Documentation: https://www.knot-resolver.cz/documentation/v5.7.7/ -- Ales Mrazek PGP: 3057 EE9A 448F 362D 7420 5A77 9AB1 20DA 0A76 F6DE
