integer overflow.
</p>
</description>
<impact type="high">
<p>
A remote attacker could send specially crafted BGP packets on a network
being monitored with tcpdump, possibly resulting in the execution of
arbitrary code with the privileges of the user running tcpdump, which
is usually root.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All tcpdump users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/tcpdump-3.9.5-r3&quot;</code>
