In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the WBXML dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wbxml.c by adding length validation.

Weakness

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