<description>
|
|
<p>A vulnerability in InspIRCd allows DNS compression features to control
|
|
the number of overflowed bytes sent to the heap-based buffer "res[]" in
|
|
dns.cpp.

|
<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.

</p>

</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All InspIRCd users should upgrade to the latest version:</p>

# emerge --sync
