Microsoft Security Advisory (2719662)
Vulnerabilities in Gadgets Could Allow Remote Code Execution
Published: Tuesday, July 10, 2012
Version: 1.0
General Information
Executive Summary
Microsoft is announcing the availability of an automated Microsoft Fix it
solution that disables the Windows Sidebar and Gadgets on supported editions
of Windows Vista and Windows 7. Disabling the Windows Sidebar and Gadgets can
help protect customers from vulnerabilities that involve the execution of
arbitrary code by the Windows Sidebar when running insecure Gadgets. In
addition, Gadgets installed from untrusted sources can harm your computer and
can access your computer's files, show you objectionable content, or change
their behavior at any time.
An attacker who successfully exploited a Gadget vulnerability could run
arbitrary code in the context of the current user. If the current 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.
Applying the automated Microsoft Fix It solution described in Microsoft
Knowledge Base Article 2719662 disables the Windows Sidebar experience and all
Gadget functionality.
Recommendation. Customers who are concerned about vulnerable or malicious
Gadgets should apply the automated Fix It solution as soon as possible. For
more information, see the Suggested Actions section of this advisory.
