McAfee’s key priority is the security of our customers. In the event that a vulnerability is found within any of McAfee’s software, we work closely with the relevant security research group to ensure rapid and effective development of a fix and communication plan.

McAfee only publishes product vulnerability bulletins together with an actionable workaround, hotfix, patch, or version update; otherwise we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. 

McAfee may publish lists of known vulnerable and not vulnerable products if the product vulnerability is already generally known publicly, but no actionable workaround is ready yet.
