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.
