Multiple Windows Common Log File System Driver Elevation of Privilege Vulnerabilities

Elevation of privilege vulnerabilities exist when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. An attacker who successfully exploited the vulnerabilities could run processes in an elevated context.

To exploit the vulnerabilities, an attacker would first have to log on to the system, and then run a specially crafted application to take control over the affected system. The security update addresses the vulnerabilities by correcting how CLFS handles objects in memory
