BIND 9.20.11 ------------ Security Fixes ~~~~~~~~~~~~~~ - [CVE-2025-40777] Fix a possible assertion failure when using the 'stale-answer-client-timeout 0' option. ``055a592fd97`` In specific circumstances the :iscman:`named` resolver process could terminate unexpectedly when stale answers were enabled and the ``stale-answer-client-timeout 0`` configuration option was used. This has been fixed. :gl:`#5372` New Features ~~~~~~~~~~~~ - Add support for the CO flag to dig. ``47108af9f2e`` Add support to display the CO (Compact Answers OK flag) when displaying messages. Add support to set the CO flag when making queries in dig (+coflag). :gl:`#5319` :gl:`!10578` Bug Fixes ~~~~~~~~~ - Fix the default interface-interval from 60s to 60m. ``e8ffe3a15ca`` When the interface-interval parser was changed from uint32 parser to duration parser, the default value stayed at plain number `60` which now means 60 seconds instead of 60 minutes. The documentation also incorrectly states that the value is in minutes. That has been fixed. :gl:`#5246` :gl:`!10679` - Fix purge-keys bug when using views. ``35efa742b03`` Previously, when a DNSSEC key was purged by one zone view, other zone views would return an error about missing key files. This has been fixed. :gl:`#5315` :gl:`!10598` - Use IPv6 queries in delv +ns. ``4916fe0c6bd`` `delv +ns` invokes the same code to perform name resolution as `named`, but it neglected to set up an IPv6 dispatch object first. Consequently, it was behaving more like `named -4`. It now sets up dispatch objects for both address families, and performs resolver queries to both v4 and v6 addresses, except when one of the address families has been suppressed by using `delv -4` or `delv -6`. :gl:`#5352` :gl:`!10573`
