Background

PowerDNS Recursor is a high-end, high-performance resolving name server.

Description

It was discovered that it was possible to update the DNSSEC validation state to a bogus state for a cached record via DNS ANY query.

Impact

A remote attacker could send specially crafted DNS queries to deny DNSSEC validation.

Workaround

There is no known workaround at this time.

Resolution

All PowerDNS Recursor users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-dns/pdns-recursor-4.3.5"
