Microsoft Text-To-Speech Remote Code Execution Vulnerability

A remote code execution vulnerability exists in Windows where Microsoft text-to-speech fails to properly handle objects in the memory. An attacker who successfully exploited this vulnerability could take 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.

The security update addresses the vulnerability by correcting how the Microsoft text-to-speech handles objects in the memory.
