NULL dereference #767

Closed Bugcheckers closed 6 years ago

Bugcheckers commented 6 years ago

It seems if strchr returns NULL here, it can lead to a NULL dereference:

https://github.com/the-tcpdump-group/libpcap/blob/master/rpcapd/fileconf.c#L80

ptr = strchr(ptr, '=') + 1;

Thanks!

The configuration file reader code was a bit sloppy; I rewrote it. That should eliminate this (and other) issues.
