The PowerDNS nameserver is an authoritative-only nameserver which uses a flexible backend architecture.
A vulnerability has been found in PowerDNS which could cause a packet loop of DNS responses.
A remote attacker could send specially crafted DNS response packets, possibly resulting in a Denial of Service condition.
PowerDNS users can set “cache-ttl=0” in /etc/powerdns/pdns.conf and then restart the PowerDNS daemon:
# /etc/init.d/pdns restart
Please review the PowerDNS Security Advisory below for more workaround details.
All PowerDNS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/pdns-3.0.1"
