NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

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.
