(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
    (CVE-2008-3337).
  
Impact :

    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.
  
Workaround :

    There is no known workaround at this time."
