An attacker could attempt to exploit this vulnerability when a user interacts with a malformed embedded OLE object within a Rich Text Format (RTF) file or a Rich Text e-mail message.
If a user is logged on with administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system.
