Executive Summary

This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if used in conjunction with another vulnerability that allows arbitrary code to be run. Once the other vulnerability has been exploited, an attacker could then exploit the vulnerabilities addressed in this bulletin to cause arbitrary code to run at a medium integrity level.

This security update is rated Important for all supported releases of Microsoft Windows. For more information, see the Affected Software section.

The security update addresses the vulnerabilities by correcting how user input is validated. For more information about the vulnerability, see the Vulnerability Information section.

For more information about this update, see Microsoft Knowledge Base Article 3072633.

Vulnerability Information

Multiple OLE Elevation of Privilege Vulnerabilities

Elevation of privilege vulnerabilities exists in Microsoft Windows OLE when it fails to properly validate user input. The vulnerabilities by themselves do not allow arbitrary code to be run. The vulnerabilities would have to be used in conjunction with another vulnerability that allows remote code execution. An attacker who successfully exploited the vulnerabilities could allow a user with limited privileges on an affected system to execute code at a medium integrity level.

An attacker could exploit another vulnerability to run arbitrary code. An attacker could then, in turn, exploit these vulnerabilities to cause arbitrary code to run at a medium integrity level (permissions of the current user).

The security update addresses the vulnerabilities by correcting how user input is validated.
