Windows Security Feature Bypass Vulnerability - CVE-2019-0732

oval:org.cisecurity:def:6477

A security feature bypass vulnerability exists in Windows which could allow an attacker to bypass Device Guard when Windows improperly handles calls to the LUAFV driver (luafv.sys). An attacker who successfully exploited this vulnerability could circumvent a User Mode Code Integrity (UMCI) policy on the machine. To exploit the vulnerability an attacker would first have to access the local machine and then run a malicious program. The update addresses the vulnerability by correcting how Windows validates User Mode Code Integrity policies.
