In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an RTMPT dissector infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-rtmpt.c by properly incrementing a certain sequence value.
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
