In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset advancement.

Weakness

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