Wireshark 2.6.x < 2.6.16 / 3.0.x < 3.0.10 / 3.2.x < 3.2.3 BACapp Dissector DoS (macOS)

high Nessus Plugin ID 135856

Language:

Synopsis

An application installed on the remote macOS / Mac OS X host is affected by a DoS vulnerability.

Description

The version of Wireshark installed on the remote macOS / Mac OS X host is 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.

Solution

Upgrade to Wireshark version 2.6.16 / 3.0.10 / 3.2.2 or later.
