This vulnerability is fixed in versions 0.30.3 and 1.13.5.1dCVE-2026-59467.5 HIG76.2%
——23Multiple flaws have been identified in `named` related to the handling of DNS messages whose CLASS is not Internet (`IN`) — for example, `CHAOS` or `HESIOD`, or DNS messages that specify meta-classes (`ANY` or `NONE`) in the question section.
