An elevation of privilege vulnerability exists when the Windows Delivery Optimization service improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system 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 have to log on to an affected system and run a specially crafted script or application.

The update addresses the vulnerability by correcting how the Windows Delivery Optimization service handles objects in memory.
