The vulnerability could allow elevation of privilege if an authenticated attacker logs on to the target system using RDP and sends specially crafted data over the connection. By default, RDP is not enabled on any Windows operating system. Systems that do not have RDP enabled are not at risk. This security update is rated Important for all supported editions of Windows 7, Windows Server 2012, Window 8.1, Windows Server 2012 R2, and Windows 10. Affected Software Windows 7 for 32-bit Systems Service Pack 1 [1] Windows 7 for x64-based Systems Service Pack 1 [1] Windows 8.1 for 32-bit Systems Windows 8.1 for x64-based Systems Windows Server 2012 Windows Server 2012 R2 Windows 10 for 32-bit Systems[2] Windows 10 for x64-based Systems[2] Windows Server 2012 (Server Core installation) Windows Server 2012 R2 (Server Core installation) [1]Enterprise and Ultimate editions of Windows 7 are affected.

Vulnerability Information Remote Desktop Protocol (RDP) Elevation of Privilege Vulnerability - CVE-2016-0036 An elevation of privilege vulnerability exists in Remote Desktop Protocol (RDP) when an attacker logs on to the target system using RDP and sends specially crafted data over the authenticated connection. An attacker who successfully exploited this vulnerability could execute code with elevated privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. To exploit this vulnerability, an attacker would first have to log on to the target system by using the Remote Desktop Protocol (RDP). An attacker could then run a specially crafted application that is designed to create the crash condition that leads to elevated privileges. The update addresses the vulnerability by correcting how RDP handles objects in memory.
