Hi,

With 3.1B I have found that if an invalid source parameter is passed to
pcap_open then there is an access violation. e.g. pass "foo" as the source.
The problem appears to be in PacketOpenAdapterDAG where the result of
strstr() is used without checking that it is NULL.

I am suprised that other people haven't reported this problem. I can cause
the problem in Ethereal 0.10.3 by type in garbage for the adapter name.

Regards,

Chris Waters
