Microsoft Office OLE DLL Side Loading Vulnerability – CVE-2016-3235
A remote code execution vulnerability exists when Windows improperly validates input before loading libraries. An attacker who successfully exploited the vulnerability could take 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 vulnerability, 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 vulnerability by correcting how Windows validates input before loading libraries.
The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:
