Package : dnsruby Version : 1.54-2+deb8u1 Debian Bug : 908887 dnsruby is a feature-complete DNS(SEC) client for Ruby. It ships the DNS Root Key Signing Key (KSK), used as trust anchor to validate the authenticity of DNS records. This update includes the latest KSK (KSK-2017), that will be used by ICANN to sign the Root Zone today, 11 October 2018. For Debian 8 "Jessie", this problem has been fixed in version 1.54-2+deb8u1. We recommend that you upgrade your dnsruby packages.
