In Wireshark 3.0.0 to 3.0.3 and 2.6.0 to 2.6.10, the Gryphon dissector could go into an infinite loop. This was addressed in plugins/epan/gryphon/packet-gryphon.c by checking for a message length of zero.
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
