Overview

Affected versions of this package are vulnerable to Improper Input Validation. In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the PacketBB dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-packetbb.c by restricting additions to the protocol tree.
