-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-3223ded15e 2026-06-02 01:10:43.197439+00:00 -------------------------------------------------------------------------------- Name : unbound Product : Fedora 43 Version : 1.25.1 Release : 1.fc43 URL : https://nlnetlabs.nl/projects/unbound/ Summary : Validating, recursive, and caching DNS(SEC) resolver Description : 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. -------------------------------------------------------------------------------- Update Information: Update to 1.25.1 (rhbz#2480119) Fix CVE-2026-33278, Possible remote code execution during DNSSEC validation.
