GLSA-200812-19 : PowerDNS: Multiple vulnerabilities
medium Nessus Plugin ID 35244
Synopsis
The remote Gentoo host is missing one or more security-related patches.Description
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 (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.
Solution
All PowerDNS users should upgrade to the latest version:# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/pdns-2.9.21.2'
