<title>PowerDNS: Multiple vulnerabilities</title>
|
|
<synopsis>
|
|
Two vulnerabilities have been discovered in PowerDNS, possibly leading to a
|
|
Denial of Service and easing cache poisoning attacks.

The PowerDNS Nameserver is an authoritative-only nameserver which uses
|

a flexible backend architecture.

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 type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All PowerDNS users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-dns/pdns-2.9.21.2"</code>
|
|
</resolution>
