Microsoft Object Linking and Embedding (OLE) Automation is an inter-process communication mechanism used by languages that run on Windows. It provides an infrastructure for automation controllers to access and manipulate (i.e. set properties of or call methods on) shared automation objects that are exported by other applications.

Successful exploitation of this vulnerability could allow the attacker to could gain the same user rights as the current user. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

We recommend the following actions be taken:
- Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing.
- Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
- Remind users not to visit un-trusted websites, follow links, or open files provided by unknown or un-trusted sources.
