What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council's effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, visit the CVSS website at: http://www.first.org/cvss/.
 
When calculating CVSS scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by the successful exploitation of the issue being scored.

Where can I find a list of all Security Bulletins?
All Security Bulletins are published on our external PSIRT website at http://www.mcafee.com/us/threat-center/product-security-bulletins.aspx > Security Bulletins. Security Bulletins are retired (removed) once a product is both End of Sale and End of Support (End of Life).
 
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.
