How do I report a product vulnerability to McAfee If you have information about a security issue or vulnerability with a McAfee product, visit the McAfee PSIRT website for instructions at http:// www.mcafee.com/us/threat-center/product-security-bulletins.aspx > Report a Security Vulnerability. How does McAfee respond to this and any other reported security flaws McAfee's key priority is the security of our customers. If a vulnerability is found within any of McAfee's software or services, we work closely with the relevant security software development team to ensure the rapid and effective development of a fix and communication plan. McAfee only publishes Security Bulletins if they include something actionable such as a workaround, mitigation, version update, or hotfix; otherwise we would simply be informing the hacker community that our products are a target, putting our customers at greater risk. For products that are updated automatically, a non-actionable Security Bulletin might be published to acknowledge the discoverer.
