Summary
Microsoft Windows is affected, specifically the Win32k kernel-mode driver that handles objects in memory. A local attacker who has logged on could run a specially crafted application to execute arbitrary code with kernel privileges, allowing them to take full control of the system, including installing programs, accessing or deleting data, and creating accounts with full user rights.

Read the original description
An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. 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 system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. The update addresses this vulnerability by correcting how the Windows kernel-mode driver handles objects in memory.
