+  <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.

+  <background>
+    <p>
+    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).
+    </p>
+  </description>
+  <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 "&gt;=net-dns/pdns-2.9.21.2"</code>
