designed to cope with unreachable DNS servers.

<description>
<p>
The pdnsd team has discovered an unspecified buffer overflow
vulnerability. The PROTOS DNS Test Suite, by the Oulu University Secure
Programming Group (OUSPG), has also revealed a memory leak error within
the handling of the QTYPE and QCLASS DNS queries, leading to
consumption of large amounts of memory.
</p>
</description>
<impact type="high">
<p>
An attacker can craft malicious DNS queries leading to a Denial of
Service, and potentially the execution of arbitrary code.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All pdnsd users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-dns/pdnsd-1.2.4-r1&quot;</code>
</resolution>
