Microsoft Windows CLFS Use-After-Free Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the CLFS.SYS driver. Crafted data in a binary log file can cause a pointer to be reused after it has been freed. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of SYSTEM.
