2.6.x prior to 2.6.16, 3.0.x prior to 3.0.10, or 3.2.x prior to 3.2.3.
It is, therefore, affected by a vulnerability in the BACapp dissector
where injecting a malformed packet onto the wire or by convincing
someone to read a malformed packet trace file can crash Wireshark.

Note that Nessus has not tested for this issue but has instead
relied only on the application's self-reported version number.");
