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: https://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 https://
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 https://
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.
