The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200812-19
(PowerDNS: Multiple vulnerabilities)
Daniel Drown reported an error when receiving a HINFO CH query
(CVE-2008-5277). Brian J. Dowling of Simplicity Communications
discovered a previously unknown security implication of the PowerDNS
behavior to not respond to certain queries it considers malformed
A remote attacker could send specially crafted queries to cause a
Denial of Service. The second vulnerability in itself does not pose a
security risk to PowerDNS Nameserver. However, not answering a query
for an invalid DNS record within a valid domain allows for a larger
spoofing window on third-party nameservers for domains being hosted by
PowerDNS Nameserver itself.
There is no known workaround at this time.
