Detail

Synopsis

Two vulnerabilities have been discovered in PowerDNS, possibly leading to a Denial of Service and easing cache poisoning attacks.

Background

The PowerDNS Nameserver is an authoritative-only nameserver which uses a flexible backend architecture.

Description

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.

Resolution

All PowerDNS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/pdns-2.9.21.2"

Description: Brian Dowling discovered that the PowerDNS authoritative name server does not respond to DNS queries which contain certain characters, increasing the risk of successful DNS spoofing (<a href="http://security-tracker.debian.org/tracker/CVE-2008-3337">CVE-2008-3337</a>). This update changes PowerDNS to respond with SERVFAIL responses instead.
