In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the DMP dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-dmp.c by correctly supporting a bounded number of Security Categories for a DMP Security Classification.

Weakness

The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
