"The version of McAfee Agent, formerly McAfee ePolicy Orchestrator (ePO) Agent, installed on the remote host is 5.6.x
prior to 5.7.1. It is, therefore, affected by a missing authorization vulnerability that allows local users to block
McAfee product updates by manipulating a directory used by MA for temporary files. The product would continue to
function with out-of-date detection files.

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