Thanks for this report, Vladimír! Out of curiosity, are there any test suites available that exercise this particular attack? I'm trying to sort out a backported fix for the version of knot-resolver in debian stable (1.2.0) and enough of the codebase has changed that it's not as simple as just cherry-picking patches f90d27de49c9d3be0424d5d5457fb18df7d5c3f3 and d296e36eb554148f3d6f1f86e8f86ddec81de962, so i want to be sure that any attempted change actually fixes the problem. --dkg
