the number of overflowed bytes sent to the heap-based buffer "res[]" in
dns.cpp.
</p>
</description>
<impact type="high">
<p>A remote attacker could send specially crafted DNS responses, possibly
resulting in execution of arbitrary code with the privileges of the
process or a Denial of Service condition.

</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>

<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-irc/inspircd-2.0.5-r1"
</code>
