Hello,
i've just tested a new PPPoE attack of my tool (Hyenae) and discovered the
following bug:
When Wireshark captures a PPPoE packet with set PADI code, ID=0 and an Empty
Service-Name tag it completely hides the Service-Name tag within the packet
comparison. If the Service-Name tag is not empty, it is diplayed properly in
the comparison.
According to the RFC for PPPoE, an empty Service-Name tag on PADI packets is
valid and can be used to accept any service offer.
