Microsoft Security Bulletin MS11-038 – Critical
Vulnerability in OLE Automation Could Allow Remote Code Execution (2476490)
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in Microsoft
Windows Object Linking and Embedding (OLE) Automation. The vulnerability could
allow remote code execution if a user visits a Web site containing a specially
crafted Windows Metafile (WMF) image. In all cases, however, an attacker would
have no way to force users to visit such a Web site. Instead, an attacker would
have to convince users to visit a malicious Web site, typically by getting them
to click a link in an e-mail message or Instant Messenger request.
This security update is rated Critical for all supported versions of Microsoft
Windows. For more information, see the subsection, Affected and Non-Affected
Software, in this section.

Vulnerability Information
OLE Automation Underflow Vulnerability – CVE-2011-0658
A remote code execution vulnerability exists in Object Linking and Embedding
(OLE) Automation. An attacker who successfully exploited this vulnerability
could gain the same user rights as the logged-on user. If a user is logged on
with administrative user rights, an attacker could take complete control of
the affected system. An attacker could then install programs; view, change, or
delete data; or create new accounts with full user rights. Users whose accounts
are configured to have fewer user rights on the system could be less impacted
than users who operate with administrative user rights.
