Multiple Windows Library Loading Remote Code Execution Vulnerabilities

Multiple remote code execution vulnerabilities exist when Windows improperly validates input before loading libraries. An attacker who successfully exploited the vulnerabilities could take complete control of an 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.

To exploit the vulnerabilities, an attacker would need access to the local system and the ability to execute a specially crafted application on the system. The security update addresses the vulnerabilities by correcting how Windows validates input before loading libraries.

The following tables contain links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:
