Description Martin Beran 2008-04-08 15:10:00 UTC 
Library net/libnet10 defines structures for contents of network packets.
Fields of the packets have fixed size according to the respective protocol
definitions, but the library uses type u_long for some of the 32bit fields.
This is a problem on amd64 architecture, where type long has 64 bits. On
amd64, libnet creates packets with bad contents.

How-To-Repeat: Try to send network packets created by net/libnet10. For example, Snort in
inline mode uses libnet to send TCP reset if a packet matches a reject rule.
The packets are invalid, which can be easily seen by tcpdump.
