In Wireshark 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the Bazaar dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-bzr.c by ensuring that backwards parsing cannot occur.
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
