--
When a TCP segment contains the end of two or more SSL PDUs, the TCP reassembly
code passes that segment up to the SSL dissector multiple times--one for each
SSL PDU. The SSL dissector queues the packet for SSL tap listeners each time it
is invoked. Therefore a single packet can be processed by SSL tap listeners
multiple times. But the tap data that the SSL dissector sends to its tap
listeners is a linked list of all PDUs in the packet.
The SSL tap listener responsible for populating the Follow SSL Stream dialog
did not account for the possibility of seeing a packet multiple times. As a
result, it would process the entire linked list of PDUs each time it received a
packet, and that would result in some SSL PDUs showing up two or more times in
the dialog.
