high Nessus Plugin ID 135857

Language:

Synopsis

An application installed on the remote Windows host is affected by a DoS vulnerability.

Description

The version of Wireshark installed on the remote Windows 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.
