Descriptions

Microsoft Windows 7 SP1, Windows Server 2008 SP2 and R2 SP1, Windows 8.1 and Windows RT 8.1, Windows Server 2012 and R2, Windows 10 Gold, 1511, 1607, 1703, and Windows Server 2016 allows an elevation of privilege vulnerability due to the way that the Windows Common Log File System (CLFS) driver handles objects in memory, aka "Windows CLFS Elevation of Privilege Vulnerability".

Microsoft Windows 7 SP1, Windows Server 2008 SP2 y R2 SP1, Windows 8.1 y Windows RT 8.1, Windows Server 2012 y R2, Windows 10 Gold, 1511, 1607, 1703 y Windows Server 2016 permiten una vulnerabilidad de elevación de privilegios debido a la forma en la que el controlador Common Log File System (CLFS) de Windows gestiona los objetos en la memoria. Esto también se conoce como "Windows CLFS Elevation of Privilege Vulnerability".

This vulnerability allows local attackers to escalate privileges on vulnerable 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 Common Log File System (CLFS) driver. A crafted call to this driver can trigger access to memory prior to initialization. An attacker can leverage this vulnerability to escalate privilege to the level of SYSTEM.
