Review the Release Notes and the Installation Guide for instructions on how to install these updates. All documentation is available at https://docs.mcafee.com . Migration See the Migration Guide for instructions to get to a protected version. IMPORTANT: When upgrading to the appropriate ATD version with the fix, you must use the migration package. Failure to use the correct migration package causes installation failures and requires a reimage of the appliance. Acknowledgments McAfee credits hoangcuongflp for responsibly reporting these flaws. Frequently Asked Questions (FAQs) How do I know if my McAfee product is vulnerable or not For Appliances: Use the following instructions for Appliance-based products: 1. Open the Administrator's User Interface (UI). 2. Click the About link. The product version displays. Is ATD 4.12.2 deployable to all ATD appliance models ATD Update 4.12.2 is applicable to all ATD models - both physical and virtual.

This reimage minimizes the number of upgrade steps and avoids potential upgrade failures. See Migration Criteria . o Installation could take a minimum of 30 minutes and up to two hours. The time depends on the number of virtual machines and the database size in the deployment.

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. What are the CVSS scoring metrics 1.

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 . To report an issue, click Report a Security Vulnerability . How does McAfee respond to this and any other reported security flaws Our key priority is the security of our customers. If a vulnerability is found within any McAfee 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.
