Fix CVE-2025-11411 (possible domain hijacking attack), reported by Yuxiao Wu, Yunyi Zhang, Baojun Liu and Haixin Duan from Tsinghua University.
Summary
Unbound is a validating, recursive, and caching DNS(SEC) resolver.
The C implementation of Unbound is developed and maintained by NLnet
Labs. It is based on ideas and algorithms taken from a java prototype
developed by Verisign labs, Nominet, Kirei and ep.net.
Unbound is designed as a set of modular components, so that also
DNSSEC (secure DNS) validation and stub-resolvers (that do not run
as a server, but are linked into an application) are easily possible.
