"The version of Wireshark installed on the remote macOS / Mac OS X host is prior to 3.2.1. 
It is, therefore, affected by a denial of service (DoS) vulnerability in its WASSP dissector 
component due to insufficient packet processing logic. An unauthenticated, remote attacker 
can exploit this issue, by sending specially crafted packets to an affected host, to cause a DoS 
condition to occur in the component. 

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