TITLE

PowerDNS Recursor Input validation vulnerability

Trust: 1.4

sources: JVNDB: JVNDB-2018-014050 // CNNVD: CNNVD-201811-249

DESCRIPTION

An issue has been found in PowerDNS Recursor from 4.0.0 up to and including 4.1.4. A remote attacker sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached as failing DNSSEC validation. It only arises if the parent zone is signed, and all the authoritative servers for that parent zone answer with FORMERR to a query for at least one of the meta-types. As a result, subsequent queries from clients requesting DNSSEC validation will be answered with a ServFail. PowerDNS Recursor Contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. PowerDNSRecursor (aka pdns_recursor) is a domain name resolution server from the Dutch PowerDNS company. There are security vulnerabilities in PowerDNSRecursor version 4.0.0 to 4.1.4
