+
+ +

+ 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). +

+
+ +

+ 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. +

+
+ +

+ All PowerDNS users should upgrade to the latest version: +
