Description
CVE-2017-4028 – Craft a Maliciously Misconfigured Registry vulnerability in Microsoft Windows such that McAfee Total Protection (MTP), McAfee Internet Security (MIS), or McAfee AntiVirus Plus (AVP) allows an administrator to inject arbitrary code into a debugged McAfee process via manipulation of Registry parameters.
The issue was reported against Consumer Windows System security software – AVP, MIS, and MTP. This vulnerability allows an attacker with Windows Administrative privileges to change a registry value to allow malicious code to be injected into a process.
NOTE: A successful exploit is possible only after an attacker gains Administrative privileges on the system.
McAfee reminds users that individuals with Windows administrative privileges can control processes and change system settings. McAfee products provide a layered set of defenses against an attacker gaining entry to a Windows system. But, users should always log in with the least set of privileges required for the tasks to be accomplished. McAfee recommends that users log in with administrator privileges only when they must.
This fix resolves the issue with:

Frequently Asked Questions (FAQs)
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, please 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 successful exploitation of the issue being scored.
What are the CVSS scoring metrics that have been used?
