+ integer overflow.

+ <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 "&gt;=net-analyzer/tcpdump-3.9.5-r3"</code>
